Record high temperature in Antarctica

UNITED STATES (OBSERVATORY NEWS) — New record temperatures of 18.3 degrees Celsius have been recorded in Antarctic Gaidishli, breaking the previous record of 2015 by 17.5 degrees Celsius in the same country, Argentina’s national meteorological service reported.

The Argentine Esperanza research base thermometer, collecting data from 1961, read the historical temperature at noon on Thursday.

The temperature was 0.8 degrees higher than the previous record temperature in the country, but it was not the highest in the wider Antarctic region, including the continent, islands and adjacent waters.

On January 30, 1982, Britain’s research station on Signy Island recorded a temperature of 19.8 degrees Celsius.

A committee of the World Meteorology Organization (WMO) will now check whether this is indeed a new record for Antarctica, which is known as the largest continental land.

According to Randall Cerveny, WMO’s weather and climate rapporteur, Esperanza’s thermometer data shows a possible legitimate record, but a formal assessment of the record as well as the meteorological conditions is needed.

“The record seems to relate (in the short term) to what we call a regional ‘foehn’ event over the area: a rapid warming of air coming down a slope / mountain,” Cerveny said.
