Video of rotating convection column

Most large convection columns of smoke rising over large or intense wildfires rotate to some degree. In the video below filmed near Melbourne, Australia, the speed of the playback has been increased, making it easier to notice the rotation. To confirm this, check out the car driving by at what appears to be over 250 miles per hour.

Thanks Mike. Very interesting!

As a bonus, here is another recent convection column in Australia — a very large one with condensation on top, referred to as a pyrocumulus cloud.
