Application of Generalized Moist Potential Vorticity to Analysis and Forecast of the Torrential Rain over the Changjiang-Huaihe River Basin
广义湿位涡在江淮流域暴雨分析和预报中的应用

The generalized moist potential vorticity (GMPV), adopted by Gao et al.(2004b), is studied in this paper. It is found that GMPV, which contains information of interactions among wind, temperature and moisture, can be used in dynamic identification of heavy rain systems. Utilizing the retrieved horizontal wind from the observation data of China new generation weather radar (CINRAD-SA radar) with 1h interval, the sounding with 12 h interval and the surface observational data with 3 h interval, and the Nationa...
