The DOW documented the largest-ever-observed core flow circulation with a distance of 1,600 m (5,200 ft) between peak velocities on either side of the tornado, and a roughly 7 km (4.3 mi) width of peak wind gusts exceeding 43 m/s (96 mph), making the Mulhall tornado the largest tornado ever measured quantitatively.

A fire whirl is a vortex-shaped formation of burning gases being released from the combustible material. The genesis of the vortex is probably similar to a dust ...
In late July in the midst of the record-breaking wildfire, a powerful spinning vortex emerged that rose 18,000 feet in the air, with wind speeds exceeding 143 mph, and lasted for an hour and a half.
