Abstract:

By using the regular meteorological data and the CINRAD data, an analysis on a classical and persistent hailstorm process was made, which happened in Baise region from 12-14, March, 2013. The result shows that: 1) Circulation that was in favor of the hailstorm occurring in Baise region was as follows: the surface temperature soared as the southwest warm low controlled the region; the southwest jet stream existed at low level over the Baise region, accumulating enough unstable energy. Turbulent of the shear line and the south-branch trough at middle high triggered the releasing of unstable energy. 2) The characteristics of the physical field that lead to happening of hail weather were as follows: the Showalter Index (SI) ＜-2℃; CAPE＞500 J/Kg; unstable potential existed in middle high, as well as Δθse 850-500＞10℃; moisture condition was “dry at high level and wet at low level”; vertical velocity in the circumstance reached (-30~-10)×10-3 hPa/s；wind shear between 0~6 km was bigger than 20 m/s; 3) Characteristics of echo for the hailstorm were: in the PPI display, reflectivity of the core was bigger than 60 dBz, with the TBSS and hook shape echo nearby the core; in the RHI display, echo top exceeded the level of -20℃, with the occurrence of WER or vault. Some properties of the echo would also help to estimate the hailstorm weather, such as: the VIL soared rapidly when the hailstorm was coming. 4）For the hailstorm prediction and identification, the nowcast technics of CINRAD should be applied, based on the traditional mid-scale synoptic analysis, as to improve the service level.
