The Australian High, also known as the Australian subtropical ridge, [1] is a large, semi-permanent high pressure area or subtropical anticyclone that seasonally vacillates between the Great Australian Bight in the south to the Northern Territory in the north. [2] It is generally located between 25 and 40 degrees of south latitude, depending on ...

Satellite image showing a high-pressure area south of Australia, evidenced by the clearing in the clouds [1]. A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions.
A southerly buster is the colloquial name [1] of an abrupt southerly wind change in the southern regions of New South Wales and Victoria, Australia, which approaches from the southeast, mainly on a hot day, bringing in cool, usually severe weather and a dramatic temperature drop, thus ultimately replacing and relieving the prior hot conditions.
During the austral summer, high-pressure systems over the Great Australian Bight cause southeasterly winds to blow over the coasts of Victoria and South Australia. When winds blow parallel to the shoreline, Ekman transport pushes water to the left of the wind direction (in the southern hemisphere), which in this case is westward and offshore.
High-pressure systems are alternatively referred to as anticyclones. Their circulation is sometimes referred to as cum sole. Subtropical high-pressure zones form under the descending portion of the Hadley cell circulation. Upper-level high-pressure areas lie over tropical cyclones due to their warm core nature.
Australia sits south of the equator and under a strong, migrating zone of high-pressure called the subtropical ridge; this can lead to some interesting cloud cover. Using an advanced supercomputer climate model called GEOS-5, NASA scientists recreated 19 days of changing cloud cover over Australia. Watch the visualisation to explore the ...
The exceptional heat wave was caused by a slow-moving high-pressure system that settled over the Tasman Sea, with a combination of an intense tropical low located off the North West Australian coast and a monsoon trough over Northern Australia, which produced ideal conditions for hot tropical air to be directed down over southeastern Australia ...
