Back in January, I wrote about the importance of getting children interested in science and I talked about the Alpha 1 Ballistic Missile that was given to me by my parents. My friends and I would spend hours shooting it off in the front yard. Did I learn things? Yes! For example, I learned that baking soda and vinegar could be used as rocket 'fuel' (as an alternative to the manufacturer's fuel) and what was the best proportion of each. I also learned a number of combinations didn't work as fuel. Learning, in this case, was actually FUN. (what a novel idea)
So, it is dismay that I read that today's children's science kits may take a hit because of the Consumer Product Safety Commission. To quote the article...
Caught up in the debate are the classroom science kits and some of the items they contain, such as paper clips to show kids how magnets work.
I think it goes without saying that the Alpha 1 would never be approved today even though we had hours and hours of fun with it and no one ever got hurt. Somethings I think there are too many people who want to take all of the fun out of being a kid.

1000th Post on Meteorological Musings
This is the 1000th posting on the blog, so here is a three-in-one post.
Al Gore Heading for the Exits?
We learn from Reuters that Al Gore's firm is selling 100% of its stock in a carbon trading company. Details are here.
We Are A Force of Nature!
David Suzuki, an environmental activist, says...
“We have become a force of nature … Not long ago, hurricanes, tornadoes, floods, drought, forest fires, even earthquakes and volcanic explosions were accepted as “natural disasters or “acts of God.” But now, we have joined God, powerful enough to influence these events.”
David is Canadian and there are some parts of that great nation where tornadoes are rare, so I'm hoping he doesn't mean the above literally. Otherwise, if he stands in the path of a tornado hoping to 'influence' the storm, he will literally find himself "joining God."
Hat tip: Anthony Watts.
Thank you for the two thank you notes.
Authors love it when people like their books. I would like to thank the Kansas and Washington, D.C. readers of Warnings: The True Story of How Science Tamed the Weather for the nice cards I have received this week.
If you haven't checked out the book, go to the link above. It is terrific story of courage and overcoming the odds to save peoples' lives.
Kim and I appreciate all of our blog readers and hope you enjoy reading our blog!

The Promise of Solar Energy
While this press release is a bit technical, it demonstrates the incredible potential of solar energy.
Nanotechnology is the ability to manipulate and engineer chemicals at the level of the atom or molecule. When they speak of a billionth of a meter, a human air is 40 millionths of a meter. The size of the solar "panel" layers the release discusses are more than a thousand times thinner than a human hair!
It is quite an amazing world we are living in!

East Coast Travel Troubles
Sea Ice and Walruses
Blog Follower Steph asked me to comment on this story from NBC regarding walruses and lack of ice in the Arctic.
The contention is that lack of ice is causing them to crowd together.
There is at least one misstatement of fact in the story and that is that the tundra in Point Lay, AK is completely frozen over in September. This is not true (believe it or not, I have been to Point Lay in September). It is not true father north at Barrow, either.
If we look at sea ice extent for 2010, we see that it was low but not as low as 2008 or 2007. The reporter says that something similar happened to the walruses last year, but ice was quite a bit higher then than in 2010. So, that causes me to question whether ice extent is truly the problem.
Temperatures were colder than normal in the Arctic melt season this year as indicated on the chart below (the red line is below the green line, the latter being the long term average temperature).
So, at least to me, the problem is not immediately obvious. Yes, it might be lack of ice because 2010 was certainly below normal. But, the lack of ice was not caused by colder than normal temperature and the ice extent in 2010 was greater than 2007 or 2008.
Sorry I don't have a more definitive answer.

Today's Silly Global Warming Article
Four posts down I congratulate the Los Angeles Times for not mentioning 'global warming' in its story about the hottest temperature ever recorded there. After all, the 2010 summer as a whole in L.A. was quite a bit cooler than normal!
Unfortunately, today's Wichita Eagle couldn't resist and has an article "New York Tornadoes Just a Sign of Things to Come." The article mentions the "triple-digit heat in Los Angeles" as well as the tornadoes in NYC on September 16 as signs of 'global warming.'
See the photo below?
It is obviously a New York tornado as the Statue of Liberty is at left. The only problem is this photo wasn't taken earlier this month, it was taken July 7, 1976.
Below is a graph of world temperatures from 1976 (at left), the year of the Statue of Liberty Tornado, to present (at right).
World temperatures were much cooler in 1976 than they are now -- yet NYC had a tornado in both the cooler temperatures of the mid-70's as well as the warmer temperatures we are currently enjoying.
What does this prove? That a tornado occurring in NYC has nothing to do with global warming!
And, assuming the quote in the article is correct, I'm disappointed that NOAA would assert otherwise.

The UN to appoint an astrophysicist to be the first contact for any aliens
Apparently the United Nations believes that earth has run out of problems to solve because they are now setting up a system to handle aliens visiting from outer space. My question: Are they going to erect signs on Mars and the Moon with directions so the aliens can find this individual?

Hottest Temperature EVER in downtown Los Angeles
113°, 12:45pm Pacific time today.
The previous record? From Jan Null: The previous record was 112 degrees on June 26, 1990.
More on the hottest day from The Los Angeles Times. I congratulate them for getting through the article without once mentioning 'global warming.'

Silly Science
Part of the reason I wrote Warnings was to take the fascinating stories of the meteorologists of the last 50 years and use them as the basis for inspiration for the next generation of scientists. Scientists like Ted Fujita practiced science at its best: Open to new ideas, testing concepts to see if they worked, and they produced real results that benefit society by saving lives and saving hundreds of millions of dollars.
Today, we have a couple of examples of silly science.
Researchers at the University of Texas have learned that men prefer curvy women. Really?! Who would have ever guessed?
The second study, from England, shows that men do not notice women's shoes.
My friends in the social sciences will tell me that this research is important and the funding -- from the taxpayers -- is justified. I disagree. The social sciences have a lot to contribute, including to meteorology by helping understand how to better communicate storm warnings, for example.
But studies like these, that state the obvious, have no business being funded by taxpayers.
UPDATE: 9/30 Here is another.

"The global elite is perfectly well aware that global cooling represents a far more serious and imminent threat to the world than global warming, but is so far unwilling to admit it except behind closed doors."
More chilling information here.
At cocktail receptions at scientific dinners, I have pulled the pro-GW people aside and asked the question, "which would be worse for humanity, global warming or global cooling?" Almost most all will answer, "global cooling" but they will hasten to add, "but there is no chance of cooling."
I agree: Warmer temperatures worldwide since the 1970's, along with the Green Revolution, have allowed adequate food to be grown for the growing world population. If we cool significantly (with shorter growing seasons), all bets are off.

More Hot Air About Global Warming
Several have sent me the link to this overheated article proclaiming that hot summers are here to stay. The author, who is not a scientist, has a book coming out about global warming. I'm sure he is sincere but his faith in our ability to forecast the weather years in advance is misplaced. We simply do not have the skill or techniques required.
As I have written a number of times recently, there is good reason to believe world temperatures will be cooling in the next 3-5 years and perhaps longer.
So, lets cool the overheated and overwrought rhetoric and enjoy autumn.

The 105 mph Fast Ball
The fastest pitch ever recorded was pitched yesterday, 105 mph.
Lets look at the math for a moment: 1 mile = 5,280 feet.
105 mph = 554,400 feet per hour velocity of the ball. There are 3600 seconds in an hour. So, at 105 mph, the pitch traveled 154 ft. in one second.
It is 90 feet from the rubber on the pitcher's mound to home plate. So, the ball took 0.58 seconds to go from the pitcher's hand to home plate. It is said that the batter must decide within 0.35 seconds to decide whether to swing.
If that is the case, then the ball would have been 42 ft. from the plate when the decision had to be made. It would then take the ball 0.22 seconds to get to the plate -- much less than the blink of an eye. In that tiny slice of time, the bat must leave the shoulder and the swing must align with the ball in order to be successful.
Amazing.

Picturesque End to a Busy Weather Day
Between the shelf cloud (see below), a tornado in Comanche County, some minor wind damage, and a couple of reports of large hail, it has been a busy weather day in Kansas. It is ending on a very pretty note. The Smith House had 0.43" of rain.
The Shelf Cloud
Courtesy: Fox Sports, photographed from my TV screen
The shelf cloud that passed across Bill Snyder Family Stadium in Manhattan was time-lapsed by Fox Sports photographers as well as various still photographers (see below). The storm contained dangerous lightning and heavy rain.
Courtesy: "Wall Street Journal" online
While the cloud was unusually dramatic, highly visible shelf clouds are not uncommon in Kansas.Shelf clouds can contain very high winds, but Doppler radar correctly showed the winds with this particular storm were not particularly high. There was only minor wind damage and it was to the east of the stadium.
The game was interrupted for over an hour due to lightning. The Wildcats "won ugly," 17-13.
UPDATE: Via Jim Reed, we learn the WSJ picture was an Associated Press photograph taken by Charlie Reidel. Thanks, Jim.
From the Back Yard; Mammatus on the Move
The official name of these clouds is cumulonimbus mammatus, pouch-shaped clouds on the underside of the thunderstorm's anvil. The storms are getting closer. Stay tuned!
Severe Thunderstorm Watch
A severe thunderstorm watch is in effect from around Emporia, KS southwest to near Amarillo, TX. This includes Wichita, Hutchinson, and Woodward.
From the backyard, the top of the thunderstorms -- 50 miles to our northwest -- approach. I'll keep an eye on the weather and post anything I think might be of interest.
Ice from Sonic: Is There Anything It Can't Do?
Those of us with rain gauges know how hard it can be to keep them from getting "gunky." Kathleen read that crushed ice, swirled in the gauge, will knock off the gunk and allow it to be cleaned without scratching the interior of the gauge.
Those of us who are fans of Sonic Drive-In's know they have great crushed ice. Kathleen said, "save your ice, I want to try something" as I finished a Diet Coke with lime. She used the Sonic ice and it worked like a charm!

The Annoying Emergency Alert System Tests
Ever watched television or listened to radio and, just as the critical point in the program or a favorite musical passage comes on, it is interrupted by the annoying tones of the F.C.C. and Department of Homeland Security's "Emergency Alert System" (EAS)?
When I was a child in the 1950's, there was a system called CONELRAD that was to alert us in case of nuclear attack. And, perhaps in the 1950's, it made sense to have that system. But today? CONELRAD has morphed into a giant white elephant called EAS.
The EAS says it is designed to allow the President access to the airwaves within ten minutes in case of emergency. Fine. But, why do we need EAS? Can't the President just call up the networks?
Think back to September 11, 2001. President Bush was in Florida. As the airplanes struck, all of the networks began covering the story without any help from the President or government. They did it because it was news. No EAS notification was made. Cuban Missile Crisis? No. Oklahoma City bombing? Nope! Assassination attempt on President Reagan? Nada.
The EAS system has never been used.
Lets ask a practical question: Since we got through the Cuban Missile Crisis and September 11 with the regular news media covering the stories, do you believe the media will fail to cover a bigger crisis? Of course they will! And, just like President Bush addressed the nation from a remote location on September 11 via the regular media, he will be able to do so in a future crisis.
So, why do we need the EAS tests, infrastructure, and people to run it?
Answer: We don't.
EAS is a perfect example of a government program whose time, if it had ever come, has passed. It is time to get rid of EAS and those annoying weekly tests.

FANTASTIC book. It reads well, has just the right amount of suspense, education, and hope.
Thanks, Joel!
Some Welcome Sanity from Airport Security
Italy has decided to stop using use the "nude machines."
Say the Italians,
It said that is because they are slow and have not worked as well as had been hoped in checking for weapons and explosives.
Now, will the U.S. wise up?

Thank You, D.C.!
Am waiting at Reagan Airport for the flight back to Wichita. Had a super evening with the members of the Washington, D.C. chapter of the American Meteorological Society yesterday and very much enjoyed my presentation to the leadership of the National Weather Service this morning.
I'll have more on this topic when I get back. Sorry for the light blogging the last few days. We'll be back on track in another day or two.

Catching Up
Some unexpected personal business prevented me from posting with regard to the NYC storm. As expected, there were two tornadoes in addition to one large downburst ("macroburst").
It is interesting that NBC's Today show reported, "there was little warning." However, this report says that is not true. The first NYC tornado warning was issued at 5:20pm.
But the first tornado didn't touch down until 5:33pm -- that is 13 minutes' of warning which is the national average. For a small, line-type tornado (see the tornado types posting below), that is a good performance by the NWS. Warnings for additional boroughs came out during the next few minutes. The path length was a combined 14 miles.
Now, the point I would like to make: I have been in NYC on several occasions when severe thunderstorms have caused significant damage. But the quality of severe weather coverage is usually inferior to that in a small- to medium-sized market in the Great Plains. A quality of coverage in, say, Wichita, Oklahoma City, or Kansas City smokes anything one sees in NYC.
My point is that the warning was there. Thirteen minutes is a lot of time for the public to take shelter. WeatherData provided even more warning for its business clients! Given the type of storm, the meteorological profession performed well.
Nonsensical stories like these complaining that the warning was out only a few minutes due Reuters and its readers a disservice. The they were fast-moving storms and the NWS, correctly, issued the warnings for only a minutes duration. Does Reuters want people cowering in shelter after the sky has cleared?
Given the extensive damage, the very low death toll is likely due, at least in part, to the timely and accurate warnings.
If any of our readers in the NYC area would like to comment, I'd like to hear from you.

Tornado Types
According to the dictionary, a tornado is:
a violent destructive whirling wind accompanied by a funnel-shaped cloud that progresses in a narrow path over the land
1. Associated with supercell thunderstorms. The Greensburg Tornado would be an example. The rain-wrapped tornado below was produced by a supercell thunderstorm.
2. Associated with strong lines of thunderstorms, sometimes known as squall lines.
3. “Landspouts” which are associated with a low pressure system in the upper atmosphere (and includes the remains of huiricanes and tropical storms)
4. Gustnados which occur when dense cold air rapidly flows out of a thunderstorm into warm air flowing the opposite direction. Think of a pencil placed between your right hand moving away from your body and your left hand moving toward your body. The spinning pencil would be a gustnado. It is the weakest form of tornado. Because of their brief existence (often tens of seconds), they are the most difficult to photograph.
My good friend Jim Reed caught several gustnadoes to the southeast of Wichita Wednesday evening. In this instance, there is no visible funnel at cloud base.
This gustnado photo does show a funnel but it is questionable whether the funnel at cloud base is directly connected to the gustnado.
sWhile gustnadoes are not in the same league as a Greensburg tornado, they are still dangerous. They can overturn a tractor-trailer or a non-tied down mobile home and, as such, post a threat to life and limb. Because their duration is so short, they can be difficult to warn of. The Wichita meteorologists did a great job Wednesday evening in a tricky and violent situation.
More About Tornado Warnings
Earlier this week, I wrote about tornado warnings based solely on radar. I am asked, surprisingly often, why we cannot always visually confirm that a tornado exists before issuing a warning. Courtesy of storm chaser and photographer Jim Saueressig (web site here), we have two views of the same storm, moments apart, where the tornado is visible and when it is not.
The first photo, below, is a rain-wrapped tornado that was briefly visible in the near darkness. It was produced by a supercell in the Flint Hills near Severy, Kansas, at 7:23pm.
Even though it is still on the ground, the tornado is invisible in this view just moments later.
Even discounting tornadoes in the middle of the night, it is just too risky to hope that we can get visual confirmation of every tornado before we warn on it.
More on tornadoes later today.

The Two Most Interesting Storms of the Week...
...Were the storms in New York City yesterday and in Wichita Wednesday.
With regard to the former, the question has been, "Was New York hit by a tornado?" The question will be definitely answered by the NWS today, but I believe the answer is yes. From a quick look at the radar data, there was a small but strong low pressure system embedded in a line of thunderstorms. These sometimes produce tornadoes. Assuming the NWS confirms this, I'll have more later today.
With regard to the Wichita storm, it was unique in the way it transitioned from one producing near-record giant-sized hail to one producing small tornadoes and straight winds with gusts up to 90 mph. I'll be writing more about that one today, as well. Still waiting for some data and images to come in.
So, stay tuned!

Unique Way of Displaying Huge Hail
Via Facebook, 5 1/2" hail stones displayed next to young Carson Bieberle. Posted by Justin and Crystal Bieberle. Much of the southwest half of the city of Wichita experienced large hail.
UPDATE 2PM Thursday: As if these hail stones were not big enough, we had a 7.5" stone in southwest Wichita. Here is more from a Stormtrack posting by Mike Guekes:
The hail stone below that is pictured at 7.5 inches may have broken a new record for Kansas hailstones. The hail stone may have broken the record Diameter of any hailstone at 7.5 Inches, other stats include 15.5 Inches in circumference and 1.1 lbs. This hailstone fell near Pawnee and 119th Street in West Wichita around 6pm on September 15th, 2010. The measured circumference and weight were measured 15 hours after the event. The previous record was 5.7 Inches in Diameter, 17.6 Inches in circumference, and 1.65 lbs and fell in Coffeyville, Kansas on September 3rd, 1970.
UPDATE: 5PM Thursday. KAKE TV reports Wichita's Auburn Hills golf course was closed today due to thousands of holes pitting the course. They expect a week for things to get back to normal.
Responding to Readers' Requests...
The following is a brief, simplified explanation of where we are with global warming science:
Carbon dioxide traps outgoing radiation and increased CO2 concentration (other factors equal) should trap more heat causing a warming effect, especially at night. However, we do not fully understand the extent (i.e., linear, logarithmic*?) of that process and we do not understand its net interaction with clouds and with particles in the atmosphere (called aerosols by atmospheric scientists) to get a complete picture of its effect on the atmosphere.
There is no reliable evidence – none – that storms are getting worse because of ‘global warming.’ Increases in the dollar amounts of damage are a result of inflation and putting more and more valuable development (i.e., mansions in Miami near the coast) in harm’s way.
The United Nation’s Intergovernmental Panel on Climate Change (IPCC) has been severely compromised by a number individuals’ dishonest and anti-science behavior (“Climategate”). It is hoped the recommendations made by an independent review panel two weeks ago will result in a more scientific and trustworthy product in the future.
Current solar and ocean conditions indicate to me that the atmosphere will cool significantly in the next 3 to 5 years. The IPCC forecast is for warming. This divergence of forecasts and the data relating to them will likely give us a far better understanding of the threat posed by increasing carbon dioxide no later than 2015.
If temperatures warm in spite of cooling oceans and weak solar activity, the IPCC’s case (at least for this atmospheric scientist) would be greatly strengthened (that CO2 is the primary driver of changes in climate). Given this opportunity and based on the currently available science, there is no reason that major decisions to restructure world economies need to be made before that time.
A note for clarity: With the above said, I believe we do need to move away from traditional energy sources if for no other reason than to preserve coal, oil and natural gas as valuable chemical feedstocks. New generation nuclear (especially thorium) technology may make energy much more widely available at less cost than current energy sources.
Solar looks very promising to me.
* A linear relationship treats every extra cubic foot of CO2 the same. With a logarithmic relationship, there is a diminishing effect for each additional cubic foot. To illustrate, think of a hot tub without a cover. The first inch-thick piece of insulating styrofoam will have a much greater effect trapping heat than, say, the 20th sheet.

From the Back Yard -- A Tornadic Thunderstorm
"What Does A 'Radar Indicated' Tornado Situation Look Like"?
Radar usually cannot sense whether a tornado is on the ground or not. So, we have to look for signatures of tornado development. Below is a very nice hook echo just to the west of the I-35 symbol.
The velocity data shows rotation as well. You can see the deep red color next to the green color
And, sure enough, storm chaser Steve Worthington captured a funnel in that location. It is between the wiper and the "S" in Severe.
Out the Back Door - Severe Thunderstorms
UPDATE: 6:23PM. Tornado sirens going off as radar shows rotation near Haysville, a suburb of Wichita. Hailstones as large as softballas have been falling in west Wichita.
A tornado watch continues for the area until 10pm.
Interesting Hurricane Facts
While they were slow in coming, intense hurricanes are in progress. From the National Hurricane Center,
With both hurricane Igor and Julia reaching Category 4 strength, NOAA's National Hurricane Center reports these interesting facts:
With both hurricane Igor and Julia reaching Category 4 strength, NOAA's National Hurricane Center reports these interesting facts:
- Two category four hurricanes existing simultaneously in the Atlantic basin has occurred only one other time since 1900: September 16, 1926 (Hurricane #4 and the Great Miami Hurricane).
- There are only three other incidents of two major hurricanes (Category 3 or higher) at the same time: 1950 (Dog & Easy), 1958 (Helene & Ilsa), and 1999 (Floyd & Gert).
- Hurricane Julia is the most intense hurricane to be located so far in the Eastern North Atlantic.
A Non-Partisan Plan to Improve America – Part II
The problem is that once your representative moves to Washington from Oregon, Alabama, or wherever, they “go native” once they are inside the Beltway. That is, they start worrying much more about what the Washington Post says rather than how well they are representing their districts and states.
So, here is my suggestion that would minimize this problem once and for all:
Disperse the government! Two hundred years ago, in the horse-and-buggy era, it made sense to have everything in the District of Columbia. Now, having everything in D.C. is a hindrance rather than a help. The people manning government departments and Congress increasingly tend to be out of touch.
So, move them outside the Beltway.
Some suggestions: Move the Department of Agriculture to Wichita or Kansas City.
Move the Department of Transportation to Chicago.
The Patent and Trademark Office should go to Silicon Valley.
The Department of the Interior should go to Denver.
Health and Human Services should be in Atlanta.
The Department of Homeland Security (which includes the Border Patrol) should move to Tucson.
Get the idea?
Move everything except Congress, Supreme Court, the White House, Defense, Justice, State, and CIA outside the Beltway. This has several beneficial effects: Their employees would be more in touch with the average person and would care less about the Washington Post. Government employees (except in an emergency) should fly commercial. Make them deal with the TSA for their monthly cabinet meeting in Washington!
Taking the Transportation Department as an example, Chicago is the transportation hub of the U.S. There are many people with a high level of expertise that already live there. It would be possible to have a smaller department with a higher level of expertise in Chicago than it is in Washington.
There is an added advantage: In an age of terrorism, it would make it harder to deal a major blow to the government…too many geographic areas to hit at once.
Finally, it would dilute the effect of lobbyists: After all, Trent Lott can only be in one city at a time.
It is time for outside-the-box thinking to solve America’s problems. Feel free to pass these on to whomever you wish. I don’t seek credit – I just want to leave an America for my children and grandchildren that is as great and full of opportunity as the one I’ve enjoyed.

Climate, Agriculture and Nutrition
This is a great, easy-to-read, article concerning how agriculture would restructure if everyone became vegans and whether it would require more or less intensive farming. The answers might surprise you (I was surprised).
An important point: If the author is correct in his analysis, more vegans would make the world more vulnerable to climate change.

A Non-Partisan Plan to Improve America, Part I
I believe that most thinking people in America today believe our government is out of touch with the cares and concerns of the average person. I agree. This is not a partisan problem. – Something seems to happen when our representatives arrive in Washington, D.C.: they start identifying with their peers inside the Beltway rather than with the people who sent them to Washington in the first place. The longer they stay, the worse this problem tends to become.
Many also believe the atmosphere in Washington is toxic and detrimental to getting things done. I also agree.
So, I am going to offer a few thoughts that I believe will improve governance that can be proposed by candidates of either party. These first two have been proposed by others:
1. Term limits. Two terms in the Senate. Four terms in the House. That’s it. And, you get twelve Congressional years, period. No four terms in the House then running for the Senate. We desperately need new blood. I do not believe the Founding Fathers intended for America to be run by a professional governing class.
2. Strict lobbying prohibitions. For three years after leaving the House, Senate, or executive-level government position (paid under the Senior Executive Service pay system), persons would be prohibited from lobbying. With this prohibition, a few of them might move back to their home district (a rarity today) rather than moving to a lobbying firm.
Part II tomorrow.

A Non-Partisan Plan to Improve America
Several reviewers of Warnings have commented that I was critical of government in several places in the book. That’s true. I’m also appreciative that they (correctly) note that the criticism is non-partisan. Don’t care whether Republicans or Democrats run our nation well – I just want it run well.
So, I am going to offer, starring tomorrow, two essays to help fix our government. Any politician, of either party, is welcome to adopt them!
A Great Compliment for Mike
Mike continues to get great feed back on his book, Warnings:The True Story of How Science Tamed the Weather. The latest comes from a fellow author:
"First of all I wanted to tell you that my husband and I loved your book. I also sent a copy to my brother for his birthday and he called a few days later to say that he read it all in one sitting and thoroughly enjoyed it. Great balance of information and entertainment. Kudos!"

Haiti in Danger..Again
At top center is the island of Hispanola, with Haiti on the west. The large weather system to the south is moving west northwest and, according to the National Hurricane Center, mudslides will result from torrential rains in Haiti. According to news reports, tens of thousands are still living in "tent cities."

More on Improving Hurricane Forecasts
From today's Houston Chronicle. I appreciate the mention of Warnings, thank you Eric Berger.
The article discusses using a B-57 bomber, manufactured in Wichita in the 1950's, and flying it at 60,000 ft. into and above hurricanes to gather data that will hopefully lead to further improvements in hurricane forecasting.

Spectacular thunderstorm to our south with lightning illuminating the thunderhead. The small dots are bugs with the nearly calm wind.
Hurricane Season ISN'T Over
I was shocked to read a blog post that somehow concluded that since Earl missed the U.S. coast (as forecast) hurricane season is somehow "over."
I believe we are going to see the tropics become quite active next week and, perhaps, the week after.
The season is hardly over. Readers near the Gulf and Atlantic coasts should not let down their guard.

BULLETIN: "Jersey Boys" Original Cast Comes to Wichita!
Hoff Longoria Reichard and Spencer LIVE IN CONCERT Has Been Cancelled.
Posted on November 16, 2010 in Arena News
Due to shceduling conflicts, Hoff Longoria Reichard and Spencer Live In Concert "HOLIDAY TWIST" has been cancelled. If you purchased tickets and paid by credit card on line or over the phone, you will be automatically refunded. If you paid by cash or at an outlet please bring your tickets… Read MoreUPDATE: Event has been moved to December 17, 2010
"It's just too good to be true!"... the original cast of Jersey Boys is coming to Wichita with their four man music show.
If you have not seen "Jersey Boys" at one of its many venues (Broadway, Las Vegas, Touring, London, Sydney), you have missed a smash musical that celebrates its fifth year on Broadway in early November.
Kathleen, daughter Tiffany, and I got to see JB six days after it opened on Broadway with the original Broadway cast and -- wow. As Tiffany said when it ended, "that was amazing!"
The original cast members of Jersey Boys will be in Wichita October 15 at Hartman Arena to sing the songs from JB as well as many non-Four Seasons songs. I got to see a little of their show on television a few weeks ago and it was terrific. This is a one time event. Tickets go on sale tomorrow.
Don't miss it!!
Yes, I Wrote "Warnings"
Thanks, Kim, for posting (below) about our trip to the University of Oklahoma.
While at the book signing, a friend I had not seen in a couple of years asked me if I really wrote Warnings or whether I had a ghostwriter. He said, "It is so well written?!" The question did not offend. I never thought I would write a book and I didn't have any idea how it would come out when I started.
Answer? Yes, I wrote the book. It was a 4+ year process. I had two great editors, Jeannette Cezanne who assisted me with whittling down the 500+ page first draft and Greenleaf's Theresa Reding who helped me put the manuscript into final form. Since he liked the book so much, I'm flattered that he asked.
A story about the editing process. I wanted Jeannette to really get a feel for what the subject was all about, so she could help me figure out what to cut and what to keep. She flew to Wichita in June, 2008, to see WeatherData, to go storm chasing, and to meet me face to face. The photo below shows Jeannette posing in front of a rotating wall cloud.
And, a few minutes later, the clouds parted enough to get some sunlight while Katie Bay (chasing with us) got this photo of a tornado (note the debris cloud near the ground).
Jeannette, who had never been to Kansas before, thought seeing a tornado (the good kind -- it did no damage as it was in open country) during a chase was routine. If only.

The $700,000,000 Weather Forecast
Hurricane Earl at a time when it was moving directly toward Florida (upper left)
Remember last week at this time when Category 4 Hurricane Earl was threatening the East Coast of the United States?
The memory has probably already started to fade because Earl just brushed the coast at the outer banks of North Carolina and far east Massachusetts. Total coastal miles put under hurricane warnings? According to the NOAA's National Hurricane Center, 450. There were no mass evacuations, just some selective evacuations in areas most threatened by the storm. Earl was an inconvenience, not a disaster -- just as it should have been, right?
Given the similar paths north of Hispanola, why was there such a difference in preparations between Earl and Floyd? The answer is simple: The great improvement in the quality of hurricane track forecasts in the last decade.
Below is the Hurricane Center's forecast path from about the time Earl was north of Hispanola.
Why is this important? It is further evidence that meteorology has "tamed the weather."
NOAA estimates that an evacuation costs between $600,000 and $1 million per mile of evacuated coast. These costs include transportation, lost wages of the evacuees, preparations (i.e., cost of lumber to board up windows, pulling boats out of the water), lost income (tourists that cancel), etc.
Lets do a little hurricane warning math: Floyd (1500 warned miles) - Earl (450 miles) = 1050 correctly unwarned miles due to the improvement in hurricane forecasting.
OK, now take those 1,050 miles and multiply them by a conservative figure of $700,000 in savings for each mile that correctly was not warned = $735 million dollars! Given the current weak economy, that is a tremendous value to the U.S. and its people!
And, when you figure in the value-added private sector hurricane forecasts issued by companies like WeatherData and its parent company AccuWeather, the savings grow further, perhaps approaching a billion dollars in total when the correct landfall forecast for Canada is factored in. I chose to go with a more conservative number in the headline.
This is the story I tell (without math!) in Warnings: The True Story of How Science Tamed the Weather. We certainly have not "conquered" the weather, but we have tamed it -- that is, we have removed a lot of its sting through more accurate forecasts, warnings, and advice that people and businesses can use to make appropriate decisions in critical situations. The story behind this unnoticed miracle of science and technology is fascinating and I hope you will consider checking out Warnings.
In the meantime, congratulations to my fellow meteorologists in general and, in particular, the meteorologists at the National Hurricane Center and my colleagues at WeatherData and AccuWeather.
UPDATE: 10AM Friday: The American Meteorological Society has more here.
"Miracle" at OU
Mike had a great time visiting the campus of the University of Oklahoma, his alma mater, on Tuesday. He gave his presentation, Miracle at Greensburg, and did a book signing for his book, Warnings: The True Story of How Science Tamed the Weather. The Meteorology department and the National Weather Service are housed in the same beautiful building, and many were present for the presentation. Thank you OU , for the opportunity.
2010 versus 1957 Dallas Tornadoes
UPDATED FRIDAY EVENING: While shorter, the 2010 tornado was very similar to the 1957 tornado. Here is a map of the path of the '57 tornado at left and the 2010 tornado at right. Note Love Field as a point of reference in both.
Photo of 1957 Dallas tornado. Compare to WFAA's photo of yesterday's tornado below.
Yesterday's tornado in Dallas followed a path very similar to the path of the 1957 tornado, the only major tornado in the history of the city. The storm killed 10. There is more here.
Anniversary of the Galveston Hurricane
Today is the 110th anniversary of the Galveston Hurricane of 1900. The hurricane killed about 8,000 people and is the topic of the excellent book, "Isaac's Storm." Isaac was Isaac Cline of the Weather Bureau's meteorologist assigned to the Galveston office.
Eric Larson did a great job on the book -- a story about science that is gripping and engaging.
AccuWeather has more on the anniversary.

Two Tornadoes in Dallas
Dallas has been remarkably tornado-free throughout its history. However, a tornado -- spun off from the remains of Tropical Storm Hermine -- has been doing damage in the Dallas area for the past half hour. I'll have updates when there is more information.
Here is an image of the amazing hook echo just left and slightly above the "D" in Dallas. The tornado crossed I-35E near the Lowes Hotel. There is some damage.
Photo from WFAA TV. It is of the tornado crossing the Trinity River west of downtown Dallas.
From KXAS TV (NBC). The debris cloud is at bottom with the thin funnel cloud above.
There were apparently two tornadoes, one near Seagoville and a second from just west of downtown Dallas toward Love Field.
Here is the Seagoville tornado, also from KXAS.
Tornadoes often occur with the remains of tropical storms and hurricanes. The good news, if there is ever any good news when it comes to tornadoes in populated areas, is that those tornadoes are relatively weak. You don't get a Greensburg-type tornado in this type of weather situation.
Finally, this screen capture of KDAF TV's coverage. The tornado is about to lift as it crosses I-35E. But, if you view the video you see the car (bottom center) on the access road skid when the rapidly-weakening tornado hits it. I wonder if the driver knew what hit him/her?
There has also been flooding in the Dallas Metroplex. From The Dallas Morning News...
Flash floods claimed at least two lives in Texas, closed down Interstate 35 in Lewisville and led to dozens of swift-water rescues across the region. The most precarious came in Arlington, where firefighters used a lowered aerial ladder as a bridge to carry trapped residents from the Willows Apartments at Valleywood Drive and West Pioneer Parkway, where cars were covered to their roofs by the rising waters of Rush Creek.
I have been viewing a number of the Dallas TV stations live on the internet plus KSNW TV (NBC) in Wichita broadcast the Dallas tornado live during their 6pm weathercast. I marvel at how routine it is these days for tornadoes to be broadcast live. I tell the story about the first live broadcast of a tornado (1974) and the development of color weather radar in Warnings: The True Story of How Science Tamed the Weather.
