La Niña maintains its strength
La Niña continues in the tropical Pacific.It
typically increases the chance of above-average rainfall for northern and eastern Australia during spring and summer. it also increases the chance of warmer days and nights in northern Australia during spring.
The negative Indian Ocean Dipole (IOD) persists. The latest weekly ocean IOD index is neutral for the first time since June, but cloud and rainfall patterns remain typical of a negative IOD.
A negative IOD typically increases the chance of above-average spring rainfall for most of the central and eastern areas of Australia. It also increases the chance of warmer days and nights in northern Australia during spring.
The Southern Annular Mode (SAM) is positive and likely to continue into December.
During the spring and summer months, a positive SAM increases the chance of above-average rainfall for parts of eastern New South Wales, eastern Victoria, and south-eastern Queensland. It also increases the chance of below-average rainfall for western Tasmania.
Sea surface temperatures around Australia are much warmer than normal. Waters in the northern tropics and the Coral Sea set new October records. Warmer Australian waters, especially in the tropics, can cause greater evaporation, humidity, cloudiness and rainfall.
Climate change continues to influence Australian and global climate. Australia's climate has warmed by around 1.47 °C in the period 1910–2020. There has also been a trend towards a greater proportion of rainfall from high-intensity short-duration rainfall events, especially across northern Australia.
