| 摘 要： | 利用1948-2010年NCEP／NCAR春季逐日再分析资料，采用倒算法计算了青藏高原地区大气热量源汇的值，分析了春季青藏高原地区大气热源的气候变化特征及春季高原热力异常与前冬大气环流的关系。结果表明：春季青藏高原东部和西部为大气热源变化的活跃区域；春季青藏高原东部和西部大气热源变化表现出反相关的关系；东亚冬季风的强弱对春季青藏高原热源的异常有一定的影响。

| Abstract: | Using NCEP/NCAR spring daily reanalyzed data from 1948 to 2010 with the inverted arith- metic, the atmospheric heat sources in the Tibetan Plateau are computed. Then the characteristics of cli-mate change of the heat sources and the relationship of their anomalies with the previous winter general circulation are analyzed. The results are summarized as follows：in spring, the eastern and western parts of the Tibetan Plateau are the active variation zones of heat source. And it is found that the distributions of the spring heat source over the western and eastern parts of the plateau are opposite to each other. The spring heat anomaly over the plateau is influenced by the East Asian winter monsoon. |
