| 摘 要： | 采用一个三维中尺度动力学诊断模式，对重庆地区气象场进行了实例模拟，研究了复杂地形和不同下垫面型对流场的动力和热力作用，揭示了中尺度局地环流（山谷风、河陆风）的基本特征和变化规律，模拟结果与实测资料有好的一致性，表明该模式能够成功地模拟复杂地形局地环流。

| Abstract: | 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 |

| Keywords: | regional circulation mountain-valley breeze dynamic analysis model dynamic nudging |
