or low level fog was created by the presence of the aircraft's rotorwash
Just a quick query having followed the thread from day one, and being a Qualified Met observer, how would the above occur? Is it the low cloud in effect being blown down to the surface, or more technical than that? Interesting to me as I've never heard of the phenomena, though I am aware of the problems of heli's disturbing snow when landing.
Ta in advance ...
