Rainfall and the Southern Alps

Rainfall and the Southern Alps

When the humid westerly airstreams from the Tasman Sea reach the West Coast, they rise over the mountains and cool. Water vapour condenses as rain, which drops on the coast and the Southern Alps. Once over the mountains, the air descends and warms up, and the moisture evaporates. The winds then cross to Canterbury, on the east coast, bringing much drier weather.
