A vigorous cyclone associated with the Jet stream enhanced vorticity levels in the atmosphere, and provided ideal conditons for tornadogenesis.The cyclone caused a substantial temperature gradient over the mid-western United States, providing good air aloft. The combination of these two factors...

Kick ass day! BIG thunderstorms across Colorado this afternoon. I have maintained that few storms are driven purely by thermal updrafts but by a charged vertical current gradient. We see that the bottom layer of these storms is held firmly in place in a resonate wave pattern while the top of...

What you see is not a true tornado. Its actually a fire whirl, colloquially fire devil or fire tornado, is a phenomenon in which a fire, under certain conditions (depending on air temperature and currents), acquires a vertical vorticity and forms a whirl, or a tornado-like effect of a vertically...
