Flooding in Australia

Queensland Australia has been receiving enormous amounts of rainfall since Christmas time due to cyclone Tasha and La Nina. Before Queensland received over 30 inches of rain in the month of December (2010) they were suffering from a decade long drought. During La Nina trade winds in the Western Pacific strengthened, resulting in warmer water build-up and warmer sea surface temperatures. Thus, above average rainfall is experienced where warm water is found affecting the western pacific part of Australia. Cyclone Tasha came from warmer than average sea surface temperatures and further increased the amount of rainfall. So, overall warmer temperatures leads to warmer ocean temperatures, which increases rainfall. La Nina began in late 2010 and is still occurring in Queensland.
