A monsoon-like Southwest Australian circulation and its relation with rainfall in Southwest Western Australia
Using the NCEP/NCAR,ERA-40 reanalysis,and precipitation data from CMAP and Australian Bureau of Meteorology,the variability and circulation features influencing southwest Western Australia (SWWA) winter rainfall are investigated.It is found that the climate of southwest Australia bears a strong seasonality in the annual cycle and exhibits a monsoon-like atmospheric circulation,which is termed as the southwest Australian circulation (SWAC) for its several distinct features characterizing a monsoonal circulation:the seasonal reversal of winds,alternate wet and dry seasons,and an evident land-sea thermal contrast.The seasonal march of the SWAC in extended winter (May to October) is demonstrated by pentad data.
