I've been playing around with the mission editor. I set the wind direction to 180.
The rain now goes from the SSW to NNE.
The wave foam still goes from NE to SW
The spray goes from SW to NE still.
My conclusion is the spray is not affected by the wind direction.
I had the same problem with funnel smoke on ship's.

I tried to get the smoke to go in a direction from the ship which was a combination of the ships speed/direction and wind speed/direction (apparent wind speed/direction) by changing Local wind and Global wind parameters. Seemed to work for the combination of ship's speed and wind speed, but not direction - ie: if the wind speed was say 25 knots and the ship speed 25 knots in opposite direction smoke went straight up. However when the ship was stopped, the smoke went in the direction set by the local and global wind parameters and not the direction of the wind set in the campaign/mission ie: the rain and smoke were never in the same direction.
Perhaps rain parameters would give a clue as to how things are done? Any idea where that is set - scene.dat, but not sure that parameters there set the rain to follow wind direction.........?
