摘要
Abstract
Using the precipitation data of Wenchang station and global reanalysis gridded data of NCEP/NCAR from 1970 to 2010, this analyzed the dynamic and thermal characteristics of the non-typhoon rainstorm. The results showed that the physical of moist potential vorticity can express the dynamic and thermal characteristics of the non-typhoon rainstorms. When the rainstorm occurs, the barotropic term of the MPV is negative in low level and positive in middle and upper. Hain⁃an is in the area of moist convective instability. The baroclinic term of the MPV is smaller than the barotropic term. The dis⁃tribution characteristics of the different weather systems shows that the MPV is negative in middle and upper and positive in low level. Relatively moist potential vorticity is negative in low level and conducive to the occurrence of convection. The moist potential vorticity is one of the physical parameters of the dynamic and thermal characteristics. It will provide assis⁃tance to the forecast and warning of the rainstorm of the Hainan satellite launch site.关键词
