Nova: "Rain Bombs"

By -
This episode of Nova where they, for reasons unknown, rename wet downbursts "rain bombs" is a mis-mash. They attempt to take things weather science has known for 50 years (discovered by the late Dr. Ted Fujita) and make them new discoveries. The producers also imply we cannot forecast them. None of that is true. 

And, as you would expect, they try to tie downbursts to global warming -- in spite of a lack of evidence. 
They do have some terrific video of downbursts. The one right after Dr. Marshall Shepherd's first appearance (above) is great. If you watch, notice the curl at the lower left side of the screen as the downburst spreads out. That is the fingerprint of a downburst.

The problem is that this science, including the curl, has been known since 1978 -- there's nothing new about it. It is found in Fujita's book on downbursts. 

It feels like the producers ran out of ideas and Rain Bombs is the result. I wish it had been better.

It is imperative residents of the central Great Plains use the forecast to prepare for damaging winds and, perhaps, a tornado or two.  Tornado Risk The brown area has been moved south into northern Oklahoma and now includes Bartlesville, Ponca City, Enid, and Stillwater, in addition to the cities shown. In Missouri, it includes Joplin and Nevada.  Destructive Thunderstorm Winds Here is the color code: Pink and hatched: High  risk of destructive winds of 75 mph or stronger.  Red and hatched: Enhanced risk of wind gusts of 75 mph or stronger.  Yellow: Significant risk of winds 60 mph or stronger.  If you live in the red or pink areas, I urge  you to prepare for the potential for power outages, some could last a day or more. Bring in lawn furniture or trampolines which could blow about and crash into other objects -- increasing damage. Put your car in the garage or carport.
