Record heat in Australia: Dome of heat explained

The video explains the development of high pressure systems at altitudes between 3000 to 7600 meters. These systems can persist over regions for days to weeks, causing the air below to sink and compress, heating the lower atmosphere. This creates a heat dome effect, trapping heat and leading to extreme temperatures, such as those experienced in Australia, reaching up to 50 degrees Celsius.

How long can strong high pressure systems remain over a region?

What extreme temperature has the Australian continent experienced due to heat domes?
