The Brickfielder is a hot and dry wind in Southern Australia that develops in the country's deserts in late spring and summer, which heavily raises temperatures in the southeast coast.
[5] The dry northwesterly desert air from the interior of Australia transports dusty clouds alongside sudden hot spells that usually surpass 38 °C (100 °F) to places that feature a relatively mild climate.
These systems frequently extend inland as a narrow V-shaped depression (the apex northward), bringing the winds from the north on their eastern sides and from the south on their western.
Hence as the narrow system passes eastward the wind suddenly changes from north to south, and the thermometer has been known to fall 8.5 °C (15 °F) in twenty minutes.
[7] On the coastal plains of New South Wales, such as in Western Sydney, the Brickfielder may be exacerbated by the southeast Australian foehn.
