The Extraordinary March 2022 East Antarctica “Heat” Wave. Part I: Observations and Meteorological Drivers
Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 308–408C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of 29.48C on 18 March...

Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 308–408C temperature anomalies across the ice sheet.

The driver for these temperature extremes was an intense atmospheric river advecting subtropical/midlatitude heat and moisture deep into the Antarctic interior.
