Abstract

To take adequately account of the mountain feature in low latitude and plateau of Guizhou province,a three-dimensional dynamical numerical model over complex terrain is designed to simulate initial disturbance resulting from the thermodynamic and dynamic nonuniformity of underlying surface.On the basis of the initial disturbance,a completely elastic three-dimensional hail cloud catalyst numerical model is used to forecast the hail weather.The rate of empty forcasting decreases from 42.9% to 22.6%.The summary rate of forecast increases from 80.2% to 92.3%.
