南极半岛地区气温与南极海冰涛动、ENSO的联系

THE RELATIONSHIP BETWEEN AIR TEMPERATURE OF ANTARCTIC PENINSULAR, ANTARCTIC SEA ICE OSCILLATION AND ENSO

使用南极半岛Orcadas等台站的气温多年观测资料 ,分析了南极半岛气温和周围海冰以及ENSO的初步联系。结果表明 ,南极半岛地区的气温变化可以反映南极海冰涛动的变化特征 :气温距平和南极半岛附近海冰距平存在密切的负相关 ,和罗斯海外围区域的海冰距平存在正相关关系 ,能够较好地反映出南极半岛气温与南极海冰涛动以及ENSO之间的紧密联系。当南极半岛地区气温偏低 (高 )时 ,南极半岛周围海冰偏多 (少 ) ,罗斯海外围海冰偏少 (多 ) ,赤道中东太平洋海温偏高 (低 ) ,可能出现ElNino(LaNina)。另外 ,南极半岛当年 1 0月的气温距平对预测次年

The Relationship between air temperature at Antarctic Peninsular, Antarctic sea ice oscillation and ENSO is analysed by using the 6 weather stations observation data on Antarctic Peninsular. The result shows that air temperature variation at the peninsular can be a good reflection of the Antarctic sea ice oscillations, which means a negative correlation between air temperature and sea ice anomaly near Antarctic Peninsular; a positive correlation between air temperature of Antarctic Peninsular and the sea ice anomaly at Ross Sea. When air temperature at peninsular is in its lower (higher) stage, the sea ice near peninsular is normally more heavy (less), air temperature in middle and East Pacific sea surface temperature(SST) is higher(lower), which is connected with ElNino (LaNina). In addition, the air temperature in October has an important reference for predict SST at Nino3 region in next January.
