TEMPORAL AND SPATIAL FLUCTUATIONS OF WARMING IN ANTARCTICA AND THE ATMOSPHERIC CIRCULATION
An abrupt and extreme warming was observed in the mid-winter season, in June 1994. The air temperature increased from -72℃ to -36℃ in two days. This warming caused reduced cooling of air temperature in the winter and hence resulted in increase of the temperature throughout a month. The area of warmi...
