Updraft Speed Ranges in Different Types of Storms
Just wanted to share an interesting article found at:
http://www.stormtrack.org/forum/arch...php/t-716.html Here are some key figures extracted from it: - non-severe thunderstorm: 15 to 30 MPH (1,200 - 2,500 fpm) - severe "Multicell cluster" thunderstorms: 60 MPH (5,500 fpm) - supercell: typical 70 or 80 MPH with extremes of 150 to 175 MPH (12,000 - 15,000 fpm) Cheers, - Ido |

There is a barogram I think Ben Green made while accidentally getting sucked into a supercell in a K-6 that isn't far from these numbers. His vertical speed while in a full spin (intentional) was around 90mph. Add the 45pmh sink rate of the spin and you have a 135mph updraft. If I find it I'll scan and post it along with clarifications if the ras hivemind hasn't already filled in the correct details by then -Paul |

You can get an idea of the necessary updraft if you look at the terminal velocity of hailstones of various sizes. Tennis-ball sized hail (which I have witnessed) has a terminal velocity of more than 100 mph. Mike |

This is an interesting paper about a Grunau Baby in a thunderstorm in
Australia http://adsabs.harvard.edu/full/1949AuSRA...2..550R |

And then there's the paraglider pilot who got sucked up to 32,000' and
survived. Another paraglider caught in the same storm wasn't so lucky. http://www.flightlevel350.com/forum/...howtopic=10400 |
