Fans making a turn

by plydk
Just wander if anybody else have found these special fans that seems to make a turn to the right or left. Do anybody have an explanation for this like have the wind suddenly changed direction?

Hi there plydk. Yes, you have it right. The wind does sometimes change direction so you will find these sorts of images turning up quite often. Here's a couple from my collection:

Good hunting. Kitharode.

The nature of these fans, as seen in Kitharodes examples, indicates that the emission of the dust can be a shortlived phenomenon repeated at intervals. If it was continuous we'd see a broad fans (as can be seen in places) created as the wind changed direction while the dust was erupting.

Thanks for confirming.
I'm new to all this classifying but I find it very interresting and I am amazed how many structures and patterns I see 😃

Wassock's 'Bendy Winds' is worth a look if you haven't already seen it:
