DEVELOPMENT OF THE 2-D COUPLED STRATOSPHERIC-TROPOSPHERIC DYNAMICAL-RADIATIVE-CHEMICAL MODEL—PART Ⅰ:THE DESCRIPTION OF THE MODEL AND ITS PRELIMINARY RESULTS

In this paper,a two-dimensional(2-D)coupled stratospheric-tropospheric dynamical-radiative-chemical model has been developed,and some preliminary results have been given.From these results we can see that the latitude-height distribution characteristics and the seasonal variation of the dynamical fields such as atmospheric temperature,wind field,etc.can be effectively simulated by using this model;and the modelled latitude-height distribution of trace gases gives their distribution characteristics and seasonal variation rather well.All of these are testimony to the strong ability of the model.
