【摘要】 本文采用σ坐标系,考虑复杂地形的中尺度数值诊断模式,模拟了云南滇中地区的两次天气过程。结果表明,地面风的辐合区域与降水区有较好的对应关系;滇中地区的特殊地形对该区域地面风的辐合散有着很大的影响。更多还原

【Abstract】 A mesoscale numerical model which includes topgraphy in coordinate has been used to assess two rainfall processes in inner area of Yunnan province. The results show that the area of surface wind convergence is avaiadle to rainfall. The typic terrain of inner Yunnan great influences the convergence and divegence zones of surface wind.更多还原
