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.

该项目的目的是从辐射、动力学、云物理等多个角度探究大气中能量和物质的传输过程，以获得对地球气候及其变化的一些基本了解。下面将提到一些结果。(1)通过使用包含CISK局部强迫的简单模型，揭示了所谓的季节内振荡可以被视为局部的不稳定现象，而不是作为局部的不稳定现象。 (2)在二维气候模型的基础上,研究了CO_2的源、汇和分布,得出了认为森林砍伐可能是CO_2源的观点等结论。 （3）雷达观测表明，积云团是由两种不同空间和时间尺度的运动组成。（4）基于两个不同的数据集，分析了全球水收支情况。 FGGE 发现了一些差异，应通过未来的研究来解决。
