How do the geography and geographical features of your area affect the precipitation?

Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.

So, it mostly matters how tall the piece of land is and what grows on it...
