Tropical Cyclones over Australia
TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA), data were used in the analysis above to show rainfall contributed by tropical cyclones that have affected Australia in 2011. The tracks of tropical cyclones are shown with thin black lines. The largest tropical cyclone rainfall contribution was over the coast of northwestern Australia with estimated totals of over 600 Millimeters (~23.6 inches). Cyclones Bianca, Carlos, Twenty, Errol and their remnants were close enough to the northwestern coast of Australia to add to these rainfall totals. Cyclones Zelia, Anthony and Yasi compounded flooding from record breaking heavy rainfall over northeastern Australia. This analysis shows that the remnants of Yasi dropped heavy rainfall over the center of Australia after devastating Queensland's northern coast. Size, rainfall intensity and speed of movement are some of the factors that affect the amount of rainfall from tropical cyclones. Deadly tropical cyclone Yasi affected a very large area of Australia while Errol was relatively small and added little rain to seasonal totals as it recently brushed northwestern Australia.
