Abstract:
Based on the historical data of MICAPS, the circulation patterns of 12 hailstorms in Nanning since 2000 are classified into 3 types: the elevated (6), plateau trough (3), and SouthWest cyclone (3). The weather background, the physical factor field, and the radar product output of the three hailstorms taking place on 4 April 2009, 18 March 2017, and 7 May 2018 are analyzed by using the data from the radiosonde observation, the MICAPS data, and the Doppler radar products in Nanning. The conclusions are as follows: (1) The existence of the SouthWest cyclone plays an important role in the occurrence of hailstorms in Nanning. (2) The unstable atmospheric stratification, strong vertical wind shear, and suitable heights of 0 ℃ and 20 ℃ isotherms are the necessary conditions for hail weather in Nanning. (3) The jump of vertical liquid water content is an important means to judge whether a hail occurs or not in Nanning.
