[[File:High Pressure.jpg|thumb|left|The Australian High west of Tasmania over the [[Indian Ocean]]]]
The Australian High tends to follow the seasonal variation in [[position of the sun]]; it is strongest and most persistent during the southern hemisphere summer and weakest during winter when it shifts towards the interior of Australia, as the [[westerlies|westerly]] [[frontal system]]s becomes more active in the region around the Bight, thereby allowing cold fronts and low-pressure systems to perforate the southern states.<ref name = prevention>[https://www.preventionweb.net/news/stalled-weather-how-stuck-air-pressure-systems-drive-floods-and-heatwaves STALLED WEATHER: HOW STUCK AIR PRESSURE SYSTEMS DRIVE FLOODS AND HEATWAVES] by Steve Turton from PreventionWeb.net. 3 March 2022</ref> This high-pressure block exhibits anticyclonic behaviour, circulating the air
The High can stretch thousands of kilometers across the [[Bight (geography)|Bight]], and may move eastwards towards [[Tasmania]] towards the [[South Pacific Ocean]]. This area of high pressure is part of the great subtropical belt of anticyclones called the [[subtropical ridge]]. A [[cloud hole]] with an expansion as far as 1,000 kilometers (620 miles) has been observed, with tops of 1,040 [[millibar]]s. The high may be extensive enough to interconnect with the Tasman High over in the [[Tasman Sea]], just near [[New Zealand]].<ref>[https://www.farmonlineweather.com.au/news/high-pressure-systems-everything-you-need-to-know/527959#:~:text=High%20pressure%20systems%20are%20a,weather%20across%20an%20entire%20continent.
