At it simplest, topography forces air to move in ways it would nott over flat terrain. When air enavers a mountain, it is lifted, cooled, and often squezed of it is jughure - a process called orographic lifting.

Thee Rain Shadow Effect: Contrasts in a Single Range

Perhaps thee most dramatic illustration of topographic influence is the rain shadow effect. As moist air ascends thee windward side of a mountain range, it loses most of it s juallure them raighgh pretripitation. By the time thee air crosses thee crest and begins desceding thee leeward side, it is dry and warm. This descoverding air is compressed andd heatid adiabatically, cating a rain shaw - a region of markedy wer rainfall, often leading tdirid.
