Returning back to Norman, Oklahoma
after several days of chasing in Northern Texas, I spotted this
huge grassfire burning off towards the west. The heat from the
fire created a strong updraft of rising hot air and there was
just enough wind shear at the surface to create a dramatic Smokedevil.
It is similar to the dustdevils that are commonly seen forming
in the desert on hot, dry summer days but this was caused by
the grassfire. It formed a well defined, tight vortex of smoke
before dissipating a few minutes later. |
