Extratropical Cyclone Trends In Current And Future Climate And Associations With Southern Australia Rainfall
Grant number: DP0450831
A sophisticated cyclone locating and tracking scheme will be applied to the NCEP-2 global atmospheric reanalysis (1979-2003) to derive new and comprehensive compilations of Southern Hemisphere synoptic activity at all tropospheric levels up to 300 hPa. Trends in cyclone behaviour will be identified and related to changes in precipitation over southern Australia. The approach will be extended to results from a simulation of future climate under enhanced greenhouse conditions. The extent to which extreme cyclone and precipitation events become more numerous in a warmer world will be determined and the links between them established.
