中文摘要	The development mechanism of strong dust storm, the atmospheric dynamic condition and the surface thermodynamic condition of forming strong dust storm are studied, on the basis of demand of econ omy build, and on the basis of trend of continually increasing of the dust storm in Western China and Northern China in the recent years. These simulated and observed results unveil a positive feedback process of the radiation cooling, among the dust, the radiation, the air temperature, air pressure, and strong wind, in the dust storm development process. These theoretical results validate the physic mecha nism of forming the dust storm, and reveal good foreground of predicting the strong dust storm.
英文摘要	The studies of a key project, entitled "study of interaction between underlying surface with sparse vegetation and atmosphere" supported by National Natural Science Foundation of China from 1999 to 2003 are reviewed. The mechanisms of transport processes of water, heat, and CO2 over complex underlying surface with sparse vegetation, the complex nonlinear effects caused by the heterogeneous underlying surface, the oasis stability, the development and thermal-dynamic conditions of strong dust storm, the countermeasure building the ecological environment in the arid and semi-arid area are studied using the data analyses, the numerical experiment, and the theory analyses. The main results are as follows Revealing the sensitivity of the net first productive power and the biomass to the climate, espe cially to the mean annual precipitation. These can provide a better interface to future study the interaction between the underlying surface with sparse vegetation and the atmosphere.Developing a physic former, which expresses across coupling between the water transportation and the heat transportation in the soil, and the influence of phase transition on movements of water and heat in the soil, to be applicable to the arid and semi-arid area. A physic former that express variation of the seasonal snow cover based on the conversation law of energy and the conservation law of mass is devel oped, its simulated results are very good consistent with the observation results, which is one among several international typical delaminating formers of snow cover to achieve in-phase with international ad vanced level. Developing the nonequilibrium thermodynamics. A theorem of minimum entropy production and a theorem of minimum generalized energy of the force-dissipative dynamic system are proved in thermody- namic linear and nonlinear region. These theory advances offer potential new idea and new method to deal with the kind of complex climate and environment system. The nonequilibrium linear thermodynamics reveals that the atmospheric vertical movement (namely the horizontal convergence or divergence movement) influences on the vertical turbulent transport fluxes of maroscopic quantities. This is very important for the boundary layer of heterogeneous underlying surface and the convection boundary layer. This research provides important clue to overcome difficulties in application of the atmospheric boundary layer physics toheterogeneous underlying surface, and in the parameterization of land surface process of heterogeneous un derlying surface. The oasis microclimate, the oasis critical scale and the oasis stability are studied using the theory of nonlinear thermodynamics. The oasis physic scale and the oasis wet island intensity are im portant control parameters of thermodynamic and dynamic processes of the oasis. The results of numerical simulation of the atmospheric dynamic model show that the critical scale of forming the oasis cold island effect is about 3-6 km; The oasis wet island intensity is about 2~5 g' kg-1. On the basis of the above research stockpile, we suggest countermeasure of protecting and building the ecological environment in aridarea.(4)
