@roohairy I made a test and it seems to work correctly [image: 1726557958049-5869af19-87d0-4c03-9b5f-fd14834a5273-resized.jpeg] Here the wind layer is here dated Sat 21 - 19h

Setting to North up seems to have cured this, stupidly I didn't look at what it had been set to but guessing it was something else. Hadn't noticed this option, thanks.
