film of a tornado emerging from the wall cloud of a supercell in south dakota. a supercell is a severe thunderstorm with a deep rotating updraft. most tornados are associated with supercell thunderstorms, the largest, most severe class of single cell thunderstorms.
a tornado is created when the cooler downdraft of rear midlevel winds combine with the updraft of warm, moist and horizontally spinning surface level winds, which condense into a funnel as they’re drawn upward into what is called the mesocyclone. (video)
Thanks to a scheduled (but forgotten) power outage in Crossfield I managed to sneak away and chase this beautiful beast from cochrane to just south of indus. she didn’t end up throwing a tornado, but it had a lot of the makings. Lots of cloud lowering and so much aqua green bubbling in her. It was beautiful in the fullest sense of the word.
I was nearly killed by two deer darting in front of me while i raced down a gravel road–and managed one frame of it on the dash mounted time-lapse i was making. it was quite a day.
People don’t think of geography as being a science or geographers as being scientists. They think of science as being people wearing pretty white lab coats doing ‘stuff’ in labs. Well, I got news for you. If we could get or create tornadoes and study them inside of a lab, then you bet we’d doing it! In the meantime, we just chase storms and try not to die.
the other night i experienced the most magical two hours of my life. a beautiful super cell moved it’s way across the prairie right at sunset and broke up in the unimaginable pinks and reds. I’m still trying to collect myself and deal with the images and video.
