Tip vortices caused by low pressure making water vapour in the air condense. Nice pics!

Yeah, it comes off anything where the pressure is low enough. I've seen them on a C-130 at Farnborough a few years ago. Always cool to see. Nice shot also :o)

Yep, lots of prop aircraft can generate that, and I think it's cool.

Here's a shot I got of an Osprey with something similar:

No single drop of rain feels it is responsible for the flood.

I think just humidity in the air, me living on the East Coast most of my shows are pretty close to the ocean so you'll get the moisture just from the ocean. It's a cool effect that's for sure.
