通过对1961-2006年青藏高原原始测站资料的筛选、剔除和插补等处理,得到了一套具有51站连续的、长序列的积雪观测资料。利用国家气候中心整理的1951-2006年中国160站月降水和月平均气温资料,分析了青藏高原冬、春季积雪年代际变化特征与中国夏季降水和气温的关系,并研究了全球变暖影响下青藏高原积雪对中国大陆对流层温度、大气环流和东亚夏季风的影响。“,”A set of consecutive and long-recorded observational snow depth data with 51 observation stations are obtained through choosing,removing and interpolating original observation data in the Tibetan Plateau during 1961-2006.Using the monthly precipitation and temperature data at 160 stations in China during 1951-2006,which was collected by National Climate Center,through calculating the correlation coefficient,significance test,polynomial trend fitting,composited analysis and abrupt change test and so on,the interdecadal change of winter snow on Tibetan Plateau and its relationship to summer precipitation and temperature in China,and to tropospheric atmospheric temperature,the general circulation and the East Asian summer monsoon under the background of global warming are studied.
