| 摘 要： | 充分考虑贵州低纬、高原山区特色,建立了复杂地形下的三维动力学数值模式,模拟了由于下垫面的热力和动力不均匀造成的对流云的初始扰动,并将此模式与完全弹性的三维冰雹云催化数值模式结合,对高原山区冰雹进行数值预报,使贵州威宁地区冰雹预报的空报率由42.9%减少到22.6%,预报概括率由80.2%增加到92.3%。

| 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%. |
