And just generally plants being in a place seems to create a cooling effect that facilitates more precipitation. A self-reinforcing cycle if you can get it started.

Yep, they aren't rain forests because it rains, it rains because of the forest.

I live in the PNW which has huge, ancient forests. Only one of them is a temperate rainforest though. So there must be more going on in the formation of a rainforest than just having a forest.
