Study on the transport of energy and matter in the atmosphere

该项目的核心是从辐射、动力学、云物理等多个角度对能量和物质在大气中的传输过程进行反演，以获得对地球气候及其变化的一些基本认识。结果表明：(1)利用一个简单的模式，考虑了由CISK引起的局地强迫，发现所谓的季节内振荡可以看作是局地的不稳定现象，而不是赤道附近的波动。(2)在二维气候模式的基础上，研究了CO_2的源、汇和分布，得出如下结论：(3)雷达观测表明，积云云团是由空间和时间尺度上不同的两种运动组成的。(4)基于两个不同的FGGE数据集，对全球水分收支进行了分析，发现了一些差异，有待于进一步的研究。

The puropse of this project is to invertigate the transport processes of enrgy and matter in the atmosphere from various vienpoints such sa radiation, dynamics, cloud physics and so on, in order to obtain some basic insights to the earth's climate and its change. In what follows, some reults will be mentioned.(1) By using a simple model including the local forcing due to CISK, it is revealed that the so-called intra-seasonal oscillation could be taken as an instability phenomenon localized, but not as a wave surrounding the equator.(2) On the basis of 2-dimensional model for climate, the source, sink and distribution of CO_2 are studied, to conclude, for example, that the opinion insisting that the deforestation coulde be a source of CO_2 shoulde be denied.(3) It is revealed by radar observations that the cluster of cumuli-clouds is consits of two types of motion different in space and time scales.(4) Global water budget is analyzed, based on two different data set of FGGE, and some discrepancies are found, which should be resolved by future studies.
