摘　　要：利用改进后的大气环流谱模式 (简称 SF- AGCM)进行长时间积分 ,分别在青藏高原冬季感热、潜热减少 ,夏季感热、潜热增加和地形减半等三种情况下 ,求出其相应的我国温度情况。结果表明 :夏季感热、潜热增加 ,相应次年我国冬季普遍温度升高 ;冬季感热潜热减少 ,相应次年夏季青藏高原地区温度升高 ,我国中东部区温度降低 ,只有东部沿海的温度有少量增加 ,降低最多地区在黄河中游。青藏高原地形高度减半 ,冬季青藏高原地区温度增加 ,0℃线沿青藏高原穿过黄河和长江的中上游 ,我国的东部地区温度均降低 ,降低最大处是在渤海和黄海附近的地区 ;夏季我国普遍温度都降低 ,青藏高原的西部温度降低最为显著。此外 。In this paper,an improved spectral general circulation model is used to simulate the sensible heat,latent heat and height varations of Qinghai Xizang Plateau.The air temperature is studied and the results show that when the sensible heat and latent heat of Plateau in summer is increased,the air temperature becomes higher in winter;When sensible heat and latent heat in winter is decreased,the air temperature becomes lower over the areas of central and eastern part of China in summer,but higher over the eastern part adjoining ocean of China.When the Plateau height is lower than normal,the air temperature becomes higher in Plateau,but lower in eastern part of China in winter.While lower air temperature appears in summer,and in the Western part of Plateau it is more obvious.
