Rainfall across the Southern Alps

Rainfall across the Southern Alps

This cross-section shows the wide variation in annual rainfall within a few tens of kilometres on the western side of the Southern Alps. The highest rainfall – over 10 metres – occurs in a narrow band where the prevailing westerly winds force moist air from the Tasman Sea over the mountains. As the air rises and cools, it drops much of the moisture as rain.
