Abstract:
Using the conventional meteorological data, the NCEP reanalyzed data, in combination with Huangshan Doppler radar observational data, the hailstorm occurred in February 2009 in the Huangshan Mountain area is studied. The results indicate: (1) The hailstorm, having the feature of multiple convective cells, was induced by an upperlevel jet and a merging process of cumulus clouds. (2) The hailstorms occurring in early in spring have common features of hailstorms, and also have obvious seasonal feature: the combination emissivity is also very high, but because the column temperature is relatively low, compared with early summer hailstorms, the vertical liquid water content is smaller, and the height of -20 ℃ was 1 to 2 kilometers lower.
