Prime time for dust devils in Saskatchewan

Saskatchewan is mostly flat, mostly dry and with temperatures heading into the 20s, conditions are ideal for the formation of 'dust devils'.

The short-lived,whirling vorticesofwind occur on sunny days when warm air rises into a pocketof cooler air above.

A Saskatchewan farmer who uses the Twitter handle @skjdfarmerrecently captured video of one in the west-central part of the province.

By the way, not everybody calls them dust devils. In Australia, they're willy-willies, in Iran, they're roundwinds, and in Death Valley, Calif., they'resometimes calledsand augers.
