Cloud on the hills

[mtbc]

Our village lies on an alluvial plain with the the river to the south and the Sidlaws to the north. As I look north to those hills I often see low cloud or mist hanging over them. One science of which I know very little is meteorology: I don't know if the hills cause the cloud or attract it or what, nor do I know if their position with respect to the river and the plain and the prevailing winds is a relevant factor.

TL;DR yes, clouds (and rain) is often related to air masses moving over hills - https://en.wikipedia.org/wiki/Orographic_lift

Aha, thank you. That will be part of the story as to how the Grampians and suchlike protect us from the rain coming in from the west to make us so sunny here.
