Some of you probably know by now and some of you probably don't but new video of the Jarrell Texas tornado in its rope stage had surfaced a couple weeks ago. The motion of it in the rope stage is completely insane imo.
You might want to read this paper on the Jarrell event: http://www.nws.noaa.gov/om/data/pdfs/ctrltx.pdfReally cool footage - great find @L Dobson!
If this was a special effects reel for a movie, I love how many "rules" I would criticize it for breaking
- It's backlit so we are looking west, so the movement must be north to south. Dumb, tornadoes move north or east here.
- The funnel emerges from a featureless cloud base with no parent circulation overhead - lazy storm structure modeling.
- At 2:36 the ground circulation is "leading" the overhead vortex. Stupid - everyone knows the ground circulation drags behind the movement of the higher portions of the funnel and the parent circulation.
I'd forgotten how much I want to see a wide, continuous shot of the evolution from that single-suction vortex into the huge F5. Even reading a description of what it looked like from an experienced chaser during that evolution would be great.
