Researchers uncover the cause of sudden heatwave in the Antarctic

Australian Antarctic Division Senior Researcher Dana Bergstrom has revealed that a heatwave in Antarctica in 2022 was a result of a joining up of tropical cyclones. In 2022, Antarctica experienced an exceptional heat event which broke records when the region recorded a new all-time high temperature of minus 9.4 degrees on March 18 near Concordia Station. “What we found was that heat poured in from the tropics into the Indian Ocean area,” Ms Bergstrom told Sky News Australia. “During the February – March time, there were 12 tropical storms, and five of them turned into tropical cyclones. “Few of them joined together and then got picked up by a jet stream and took this hot, warm, moist air from the tropics ... all the way to Antarctica.”
