Abstract:
Rainfall over Southern Australia has been decreasing since the late 1960s. However, the contributions of natural variability and the climate change forcing are inconclusive from past studies performed with observations and climate model experiments. In this study we will examine rainfall trends on a seasonal basis and changes in atmospheric circulation that may have led to this long-lasting rainfall decrease. Variables required: rainfall, geopotential height, mean-sea level pressure, surface screen temperature, soil moisture, radiative and turbulent heat fluxes , and potential evaporation.
