The result shows that : the sand - dust storm occured in favorable climate background that is drought and rainless, the tilted trough and mongolia cyclone are the important weather systems that caused the severe sand - dust storm, tilted trough and strong frontal zone caused the mongolia cyclone developed and the clod front strengthened at surface, high jet and ferrel circulation are the main reason that momentum spreaded downward from higher level and frontal zone strengthened on lower level
結果表明:沙塵暴是在乾旱少雨的有利的氣候背景下產生的。斜壓槽和蒙古氣旋是觸發這次強沙塵暴天氣過程的重要的天氣系統,高空斜壓槽和強鋒區促使了地面蒙古氣旋的發展和冷鋒的加強,誘發沙塵暴天氣。高空急流及其下方的ferrel環流起到了高層動量下傳和加強低層鋒區的重要作用。( 4 ) there exist close relation between the floods season precipitation in northeast china and the anomalies of subtropical summer monsoon, the anomalies of cold air, sub - tropical anticyclone, polar front jet, north hemisphere general circulation anomalies in winter
( 4 )東北汛期降水與西南夏季風、北方冷空氣、副熱帶高壓、極鋒急流、前期冬季環流異常密切相關。Is a cold pool necessary for the maintenance of a squall line produced by a cold front aloft
冷空氣堆(冷池)對于高空冷鋒產生的的雹線維持是否是必要的?Based on t213 and other observational datasets, a severe heavy rain occurred in changjiang - huaihe basins during 4 - 5 july 2003 is studied. the primary diagnostic analyses show that double or single block is the characteristics of the macroscale circulation in this rainfall process. the strong conflict of warm and cold mass, mesoscale convergence on meiyu front, shear line, and stably maintaining of high and low jets make for the rainfall
本文採用地面高空常規資料,每6h一次的降水資料,以及t213數值預報資料,對2003年7月4 - 5日發生在江淮地區的一次梅雨鋒暴雨過程的影響系統及其可能機制進行了初步的診斷分析,發現,高緯雙阻、單阻形勢是這次暴雨過程發生的大尺度環流特徵;冷暖空氣的激烈交鋒、梅雨鋒上的中尺度輻合線、 700hpa 、 850hpa上的低渦、切變線以及穩定維持的高低空急流是導致這場暴雨的直接影響系統;該地區維持一個高能、飽和、潛在不穩定的環境,有利於特大暴雨的產生和維持。The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸;西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強,位置東西擺動預示高原地區將有降水產生,中心強度減弱,降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。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。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
