【 摘 要 】

An inverse calculation method of a simple serial RC circuit model (RSRC model) has been implemented to construct a more appropriate model in order to explain the process of warming (cooling) of the atmosphere and the surface in a period of day and night, as well as to determine the relaxation time related to it. Testing of the model involving only radiation mechanisms lead to the conclusion that the better values of relaxation time can only be obtained when the interaction between the atmosphere and the surface are taken into account. Meanwhile, with a few flaws that still encountered, the results of the study recommends the need for the development of a model with a mechanism involving convection and phase transformation, while also increase a physical dimension of the depth of the surface layer.
