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。

Although the knowledge of wind effects on tall buildings has significantly improved over the last decades, an understanding of the mechanism that the atmospheric flow field to various wind include effects on structures has not been developed sufficiently for formulation of functional expressions. not only is the wind approaching a building complex, but the flow pattern generated around a building is complicated by the distortion of the mean flow field, the flow separation, the vortex formation, and the wake development
在過去的幾十年裡,雖然人們對高層建築風效應的了解已有顯著提高,但對大氣流場與結構物各種風致響應的關系還不能用解析表達式加以描述。由於平均流場的奇變、流動分離、旋
渦形成以及紊流的發展,不僅使得流向建築物的風,而且使得繞建築物的流譜變得十分復雜。
They make sure the definite of the necw, the spread of the necw, the start time of the necw. above all, the study of the meso - scale system gives much help in analysis the necw. mr. shou shaowen studied the wet whorl q - vector divergence and relative whorl " in several rainstorms, which occurred in guizhou, and get some useful conclusions

Mss adopt pairs set of transmission, make two swirl form convection, increase water power shear function, and impel the wasted paper to accelerate hydrate andpulp. meanwhile the knife is adjustable, it can increase the pulp range. in can increase the pulp range. in thecourse of operating, wasted paper in high - speed is adverse current always. it makes paper and paper produce friction each other in order to reach the breaking to pieces fast of paper and raise the efficiency
