Using NCEP/NCAR spring daily reanalyzed data from 1948 to 2010 with the inverted arithmetic,the atmospheric heat sources in the Tibetan Plateau are computed.Then the characteristics of climate 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.
