Why does precipitation fall mainly on the windward side of a mountain? When humid winds blow from the oceans toward mountains they must rise up to pass over the mountains. The rising warm air cools when it rises and its water vapor condenses, forming clouds rain or snow falls on the windward side of the mountain. microclimate Climate within a small area that differs significantly from the climate of the surrounding area
Precipitation takes place when water condensation becomes sufficient that water droplets are heavy enough to fall back to the surface of the Earth. Precipitation is a very common phenomena in the atmosphere of our Earth.This precipitation always comes from clouds. Yet most clouds do not form precipitation.his is because the water droplets and ice crystals found in most clouds are too small, and thus not heavy enough to fall to the surface of the Earth.
