摘　　要：利用青藏高原冬季异常积雪资料对比分析了 1 985年冬季异常少雪和 1 986年冬季异常多雪时期大气环流及热带海洋特征。分析结果表明 ,高原冬季多雪与少雪时中高纬度大气环流显著不同。与此同时 ,低纬热带环流及海洋特征也有明显的差异。探讨了造成这种差异的可能原因。By using accurate snow cover data on Tibetan Plateau, the atmospheric circulation at mid high latitudes and tropical ocean features are analyzed in the abnormal less snow year 1985 and the abnormal more snow year 1986, and the pronounced differences are ravealed between the two years. And the tropical circulation and ocean features are also quit different. Finally, the cause of all these differences is discussed.
