Australian monsoon

Monsoonal troughs in northern Australia in February 2023, with some developing into tropical cyclones. When the deep lows are significant, they can affect the south as well.[1]

The Australian monsoon (AUM), also known as the Australian summer monsoon (ASM),[2] and the Australian-Indonesian monsoon (AIM),[3] is a monsoon system that increases thunderstorms and rainfall over many areas of Indonesia and northern Australia, from the far northern tropics of the region to the semi-arid zone of Australia, typically between November and mid-March, which is the wet season of many parts of northern Australia and Indonesia.[4][5]

The origin of the Australian monsoon (AUM) is comparable the North African monsoon, since both develop from the seasonal motion of the Intertropical Convergence Zone (ITCZ) and the connected meridional shift in the overturning Hadley circulation, which lead to a pronounced rainfall seasonality.[5] From the end of the 19th century, the force of the Australian monsoon has been measured by the summer precipitation at Darwin.[6]
