Climate In Australia

This affects rainfall in southern and central Australia. A positive IOD (warmer water in the western Indian Ocean) tends to suppress winter rain over Australia, worsening drought, while a negative IOD brings wetter conditions.

Australia is an island, but its surrounding oceans act differently. The warm waters of the Coral and Timor Seas fuel tropical cyclones (called "cyclones," not hurricanes) that batter the northwest coast between November and April. The cold, northward-flowing current off the west coast of Tasmania helps keep that island cool. climate in australia
