Monsoon Trough Continues to Drench Northeastern Australia

TRMM image of Monsoon in Australia
Low pressure centers associated with a summer monsoon trough have repeatedly drenched Australia from central Queensland to northern New South Wales. The clockwise rotation of these low pressure centers have continued to pump warm moist air from the Coral Sea over these areas resulting in severe flooding. Thousands of Australians have been displaced by this flooding. The current La Nina conditions are predicted to continue causing heavy rainfall over northeastern Australia. Data from the TRMM satellite are used to calibrate rainfall data merged from various satellite sources. This TRMM-based

Iggy Rainfall Hits Australia

TRMM image of tropical cyclone Iggy
On 2 February 2012 at 1044 UTC the TRMM satellite again saw weakening tropical storm IGGY as it was approaching the coast of southwestern Australia. Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that bands of heavy rainfall measuring over 50mm/hr (~2 inches) were hitting coastal areas northwest of Perth, Australia. A red tropical storm symbol shows where Iggy's center was located.
