The above analysis showed that this heavy rainfall event took on obvious meso - scale characters and was the combination of the three flows, so we can deduce : ( 1 ) surface southeasterly wind and topography may play the main role in this event ; ( 2 ) the easterly cold air rushing into the southern shaanxi province in the lower troposphere was strongly relative to the form of surface cold - front type of occlusion ; ( 3 ) there were two reasons for the secondary circulation ' s strengthen in the evening, one was the effect of a mountain - valley wind and the other may be latent heat leading to ascending motion ; ( 4 ) the shape of potential instability stratification corresponded well with the development of the warm - moisture advection ; and ( 5 ) the vapor providing essential thermodynamics was transported by a southwesterly low - level jet from the bay of bengal and the south china sea. furthermore, with the effect of terrain, the southern shaanxi province became the center of this extremely heavy rain process
中尺度結構分析表明,本次暴雨具有明顯的中尺度特徵,是由三支氣流共同作用的結果,分析發現( 1 )地面東南風和地形在這次大暴雨過程起主要作用; ( 2 )東路冷空氣主要是通過中低層侵入陜南地區的,並與地面冷式錮囚鋒的形成密不可分; ( 3 )夜博士論文:中尺度地形對陜南暴雨的影響研究間垂直次級環流發展加強可能有兩個原因,一個是由於地形山谷風的作用,另一個是降水的潛熱釋放激發了上升運動: ( 4 )位勢不穩定層結的形成與低層暖濕平流的發展有很好的對應關系; ( 5 )本次暴雨的水汽主要靠偏南風急流將孟加拉灣和中國南海的水汽輸送至西北地區東部,為暴雨的發生提供了必要熱力條件。Because of laser ' s transient heating and fast cooling on metal surface, laser cladding ceramic reinforced composite layer on titanium alloy surface can greatly improve wear resistance of titanium alloy
