Lake Eyre
Rainfall is one of the most influential climatic processes that acts upon the Lake Eyre Basin. The Lake Eyre Basin receives more rainfall during the summer season due to the high-pressure ridge of the Handley Cell. Likewise, the basin receives less rainfall during winter. Statistics from the Australian Bureau of Meteorology show that rainfall in winter totalled 8mm whilst in summer it was 38mm. This is more profound in Lake Eyre and the basin’s South Australian territories, with an average annual rainfall of roughly 125mm, yet its average evaporation can reach over 3600mm. Consequently, this is the cause of the semi-arid and arid terrain found throughout South Australian Lake Eyre territories.
