We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful
綜合分析認為： （ 1 ） 、這次冷渦在其發生發展過程中，其移動路徑是沿經圈直線南壓，攜帶的冷空氣勢力較強，形成槽后較強的垂直運動； （ 2 ） 、西太平洋副熱帶高壓偏北位置與東北冷渦南壓形成的急流軸，把源源不斷的西南暖濕氣流輸送到遼西地區，也就是急流軸的左前方位置，為這次暴雨的產生提供了充足的水汽來源； （ 3 ） 、低空急流不但為暴雨輸送水汽，其造成的較強的垂直環流也是產生強降水的一個主要原因； （ 4 ） 、 mm5模式以四維同化資料作為初始場，最大限度地避免了觀測誤差可能造成的積分不穩定，提高了模擬結果的參考價值。 -
