And if anybody has any questions feel free to jump in, you know, you can ask or whatever the case is. Okay, so, um, tornadoes sort of fall into two atmospheric families, uh, and they're basically super cellular tornadoes and non-super cellular tornadoes. And super cell tornadoes are basically, they have a top-down formation mechanism, uh, and they're associated with a rotating mesocyclone, right? So the core of the storm or the main updraft is spinning around, and then a number of other things happen near the surface. You have various down-traps, a four-flank down-drop, but the one that's important is what we call the RFD, the rear-flank down-traps, and then the way that interacts with the air at the surface, um, and the inflow, and you'll have an occlusion of the curve sort of behind the mesocyclone, and then a tornado-oform, right? And some computer modeling has shown recently that, um, as the column of air stretch, you get these upward vertical velocities.
