Cool change

From Glossary of Meteorology

Cool change

A summertime cold frontal passage in southeast Australia where strong, hot, and dry northerly (i.e., poleward) winds from the continent are replaced with much cooler southwesterly (i.e., equatorward) winds from the Southern Ocean. The hot air with temperatures as much as 40°C can be replaced by cooler air with a 10°–15°C temperature drop in a few tens of minutes.
