THE BUDGET OF THE ATMOSPHERIC RADIATION ENERGY OVER EASTERN ASIA(3) THE HEAT BUDGET OF THE EARTH-ATMOSPHERE SYSTEM IN A CLOUDY ATMOSPHERE

This paper is the third part of research concerning the budget of the atmospheric radiation energy over eastern Asia. We have discussed following problems in this part: 1. The distribution of long wave radiation and radiative balance in a cloudy atmosphere are computed. The results indicate that, except over the Tibetan Plateau for July, the features of distribution of long wave radiation in a cloudy atmosphere are similar to those in clear atmosphere both in July and January, and that the features of the distribution of radiative balance and distribution of long wave radiation are fundamentally the same. 2. The computation of the distribution of trotospheric heat source and heat sink are carried out for eastern Asia. It is found that, the whole region is a heat sink in January and a heat source in July. 3. Finally, the computation of various kinds of heat budget of the earth-atmosphere system in the various regions over eastern Asia is made. As regards to the earthatmosphere system as a whole over eastern Asia, the heat obtained in July compensates approximately the lost in January. But only for atmosphere as a whole the heat lost is larger than heat obtained. The features of different kinds of heat budgets in different regions are different.
