Abstract: The global atmospheric heating sources/ sinks <Q₁> are calculated from the NCEP / NCAR reanalysis data for 61 a from 1948 to 2008 by the thermodynamic equation, and the basic climatic characteristics and annual variations of <Q₁> in the East Asian region are examined. The results are as follows: ( 1) The average season, month, and annual variations of the East Asia region. from the graphs we can see The <Q₁> in the East Asian monsoon region varies greatly from season to season. ( 2) the average monthly time-longitude profile in change pictures are drawn. The annual variations of <Q1> are remarkably different in the six Latitude zones of Tibetan Plateau, the East Asian continent and western Pacific, and have a descriptive analysis of the graphs.
