In this paper, we have in detail computed the budgets of radiation and heat of whole air column over the tropical and its surrounding sea areas of the west?and middle-Pacific using expedition data in the west Pacific and the monthly climatic data for the world in October-December 1986. The main results are as follows: (l)The whole air column over the equator and tropical sea areas of the west- and midddle-Pacific in October-December 1986 is a strong and abroad heat source area; but over the subtropical sea areas at both south and north sides of the above area, stronger heat sink areas; over south China sea, also independent centres of source and sink of heat. (2)The formations of above heat source areas are mainly due to the very large latent heat of precipitation, and the formations of heat sink areas, large loss of radiation. (3)The inter-monthly variations of heat source areas are evident.
