Rainfall over northern Australia (NA) in austral summer is the largest water source of Australia.Previous studies have suggested a strong zonal-dipole trend pattern in austral summer rainfall since 1950,with rainfall increasing in northwest Australia (NWA),but decreasing in northeast Australia (NEA).The dynamics of rainfall increase in NWA was linked to sea surface temperature (SST) in South Indian Ocean and the rainfall decrease in NEA to SST in Wharton Basin.
