Study on the transport of energy and matter in the atmosphere

本项目的主要目的是从辐射、动力学、云物理等多个角度研究大气中能量和物质的输送过程，以期获得对地球气候及其变化的一些基本认识。在下文中，将提到一些结果。(1)通过一个包含CISK局地强迫的简单模式，揭示了所谓的季节内振荡可以看作是一种局部的不稳定现象，而不是赤道附近的波动。(2)本文在二维气候模式的基础上，对CO_2的源、汇和分布进行了研究，从而否定了森林砍伐是CO_2源的观点。(3)雷达观测表明，积云团由两种在空间和时间尺度上不同的运动组成。(4)利用FGGE的两个不同数据集对全球水收支进行了分析，发现了一些差异，需要进一步研究解决。

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.
