On the way home from my regular Tuesday bush walk I spotted this feathery cloud
Which was the result of a bush fire in the Conondale ranges:(
I thought it was worth posting:D

Nice one Ron.
yep, they're burning off left right and centre out my way.
With luck they'll have all finished by next week so we'll have clear skies for Astrofest.

High level moisture and winds are spreading that cloud out into the shape you see. If the mid level troposphere (15-25000 feet), where that cloud is, was cold and dry, you wouldn't see it. The smoke particles act as condensation nucleii for water vapour up high and that's what forms the cloud. The wind is probably low to moderate, just enough to feather the cloud out as it moves.

Thanks everyone :thumbsup:
Clouds are very hard to resolve as to what the human eye sees:(
The feathery details where quite spectacular to the eye:eyepop:
Thanks Carl for the info:thumbsup:

Interesting pic Ron, thanks for posting it. I really enjoy clouds.

This smoke induced condensation cloud certainly does look like a twirly swirly vortex of cloud (where have Dorothy and Toto gotten to?), amlost as though someone has hade horizontal strokes with a paintbrush.
