New record of explosive warmings in East Antarctica

Antarctica is considered as an important component of the glo-bal climate system,not only because of its ability to drive global sea-level rise through ice melting[1],but also because of its stabi-lizing effect on global atmospheric energy balance/circulation[2].In recent years,Antarctica has experienced rapid climatic changes and frequent climate extremes,such as a rapid decrease in summer sea ice extent since 2016[3]and the highest air temperature recorded at Esperanza station in the Antarctic Peninsula on 9 February 2020[4].In this context,climate extremes in Antarctica have received increasing attention recently[4-7].
