【摘要】 利用ＥＲＢＥ资料分析了１９８５～１９８８年期间青藏高原地气系统辐射收支场的分布特征与几次重大天气气候事件的关系。结果表明，ＥｌＮｉｎｏ期间，高原东南部地区（Ⅲ区即９０°Ｅ以东，３５°Ｎ以南）加热场强度比高原西部地区（Ⅰ区即９０°Ｅ以西）及高原东北部地区（Ⅱ区即９０°Ｅ以东，３５°Ｎ以北）要大；ＬａＮｉｎａ期间，高原Ⅰ区的热源强度比Ⅱ、Ⅲ区大。高原热源强度大，西南季风弱，反之，西南季风强。更多还原

【Abstract】 In this paper,using the ERBE data,the distribution characteristics of energy field and their relation with several important events of weather and climate are analysed during February,1985 to December 1988 over the Qinghai-Xizang Plateau. The results show that the net radiation field in south-east of the Plateau (or Ⅲ area) is larger than that in west Plateau (or Ⅰarea ) and north-east of the Plateau (or Ⅱ area)during El Nio, but the annual means values of net radiation anomaly in Ⅰ area is larger than that in Ⅱ and Ⅲ in La Nia. The results also show that the greater (less) net radiation field is corresponding to the weaker (stronger) south-west monsoon.更多还原
