How Does a Tornado Sound?

I saw some new-to-me video a few days ago and thought you would like viewing the tornado and, in this case, hearing the tornado. To me, most tornadoes sound like a waterfall with perhaps a slightly lowered pitch. I can only recall a single tornado that sounded like a jet engine. 

Of course, the whole idea is to let storm chasers do what they do. The general public should stay as far away as possible.
