Drawn to Geoscience: Tornadoes form from…wait, the ground up?! Seriously?

At our annual meeting last week, researchers presented new findings showing that contrary to popular views, tornadoes may (might) form from the ground up versus from clouds down. Here a good summary of the work via The Washington Post. AND, we were fortunate enough to have our old friend JoAnna Wendel draw a comic describing the findings! Check it out below.

Leigh Orf has done some VERY interesting computer modeling on this subject. The computer suggests that tornadogenesis occurs near the ground as ground-level vortices are drawn aloft, bundled together, and coalesce into ‘one big one’ vortex – the tornado. Suggest you check out some of the presentations found on his YT site. https://www.youtube.com/user/Dripdrip00/videos
