Numerical Simulation of Regional Circulation in Complex Terrain
复杂地形局地环流的数值模拟研究

A three dimensional dynamics model based on hydrostatic equilibrium is used to practically simulate meteorological field in Chongqing area; the dynamic and thermal effect of complex terrain and underlying surfaces on wind field are investigated, the basic characteristic and variation rules of mesoscale local circulation (such as mountain-valley breeze, river-land breeze) are obtained; there are good agreement between the results simulated by dynamics model and experimental data; comparing with other objective analysis methods, the dynamic model can simulate regional circulation successfully
