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。The occurrence of cirrocumulus clouds indicates the distant presence of a convergent zone such as a pressure tough or a cyclone in lower levels ; or a frontal zone where cold air meets moist warm air. vigorous convection and lifting motion bring water vapour up in the sky where the water vapour sublimes into ice crystals, forming the high clouds
卷積雲的出現顯示遠處地方低層有一強輻合帶如低壓槽或氣旋或鋒面即暖濕空氣碰到冷氣團,向上爬升的交界面形成,強烈的對流和抬升運動將水汽帶到高空,在那裡水汽直接升華變為冰晶而形成高層雲。Frontal thunderstorm over the field, up and down drafts up to 40 knots
鋒面雷雨過境,上升下降氣流達40海里每秒。Frontal thunderstorm over the field , up and down drafts up to 40 knots
鋒面雷雨過境,上升下降氣流達40海里每秒。Stratiform clouds are layered clouds formed mainly by uplifting of air on a large scale, commonly seen near a front, which signifies the interface of warm, moist air climbing up cold air on encountering the latter
烏雲接日頭,半夜雨稠稠的層狀雲天氣:層狀雲主要由大范圍的氣流上升運動形成,常見于鋒面附近,即暖濕空氣碰到冷氣團,向上爬升的交界面上。A transverse secondary circulation is produced by the coupling of high and low jets, while the sinking branch of the secondary circulation providing the dynamic conditions for the dry intrusion air. during the period of the heavy rain process, dry intrusion descends southward along the intense constant potential temperature lines, which promotes the lower cyclone. in addition, the pouring of upper - level dry air not only decreases ground temperature behind the front but also increases surface pressure and velocity
由於高、低空急流耦合,在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流,次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件;進一步研究發現,干侵入沿相當位溫密集帶向南向下伸展,引起對流層低層氣旋性渦度的發展;此外,高層乾冷空氣向下注入,導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大,從而促進了新的對流運動,引起降水增強。分享友人
