WHAT IT'S LIKE TO JUST GET BY...

By now, everyone must have heard about the devastation in Enterprise, Alabama, and other surrounding areas on the March 1, 2007 tornado outbreak. 8 people were killed inside the high school as the tornado-- rated EF 3 on the Enhanced Fujita Scale-- ripped through.

I scouted out this video of some roommates emerging from their home near Ft. Rucker...



What seemed to be the random and fickle nature of a tornado (why the videographer's house was spared and his neighbor's twenty feet away wasn't) is due to a complex set of conditions inside the tornado circulation. Some of the pictures and videos I've seen of the Enterprise tornado seem to show a multiple vortex funnel, where smaller, more intense suction vortices form, circulate around the main center and dissipate. These account for why a house will be destroyed and why the one next to it won't.
