A Simplified Explicit Scheme of Phase-mixed Cloud and Precipitation
-
摘要: 该文提出一个新的混合相云降水显式方案，它预报2个云物理量，即云水（冷区为过冷云水）和降水（冷区为冰雪，暖区为雨），考虑了7种云物理过程。文中给出了详细的方程组，可以作为一个子程序供大、中尺度天气模式使用。该方案还与详细微物理显式方案和暖云方案作了实例模拟比较。Abstract: A simplified explicit scheme of phase mixed cloud and precipitation for weather forecast model is described, in which two variables, cloud water content and precipitation content (rain in warm region and ice in cold region) are calculated, respectively, and 7 kinds of microphysical processes are considered. The detailed system of equations is give, which can be used as a subroutine for macro and mesoscale weather model. The case studies of the new explicit scheme are made for comparison with warm cloud scheme and comprehensive phase mixed cloud scheme
