Rain Shadow Effect

The presence of mountain ranges in Hawaii gives rise to the rain shadow effect, causing distinct differences in rainfall patterns. As the trade winds blow across the islands, they are forced to rise over the mountains. As the air rises, it cools down, leading to condensation and the formation of clouds. This results in higher amounts of rainfall on the windward side of the mountains. The leeward side, however, experiences significantly less rainfall due to the rain shadow effect, creating drier conditions.

Kauai’s Tropical Rainforest
