| 1. | 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
本文采用地面高空常规资料，每6h一次的降水资料，以及t213数值预报资料，对2003年7月4 - 5日发生在江淮地区的一次梅雨锋暴雨过程的影响系统及其可能机制进行了初步的诊断分析，发现，高纬双阻、单阻形势是这次暴雨过程发生的大尺度环流特征；冷暖空气的激烈交锋、梅雨锋上的中尺度辐合线、 700hpa 、 850hpa上的低涡、切变线以及稳定维持的高低空急流是导致这场暴雨的直接影响系统；该地区维持一个高能、饱和、潜在不稳定的环境，有利于特大暴雨的产生和维持。 | | 2. | The result indicates that , in the course of the rainstorm in huoshan , there are obvious low - level jet of great intensity , infection of mesoscale shear line , enhancement of plus vorticity which increases intensity of convergence , improves ascending velocity and brings on precipitation , and quick enhancement of helicity which provides the basis to forecast , in addition , convergence of moisture flux and analyzed potential vorticity which reflects baroclinic convective instability sufficiently indicate the characteristics of the rainstorm
结果表明：此次霍山暴雨发生前后，存在明显的大强度低空急流，并受到中尺度切变线的影响，而且正涡度的加强引起了辐合加剧，提高了上升速度从而引起降水，同时暴雨发生前螺旋度的迅速增强，也为预报提供了根据，另外水汽通量的辐合以及分析位涡反映出的斜压对流不稳定都充分体现了这次降水的特点。 | | 3. | 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、南亚高压、低纬系统、高空急流、低空大风速轴；西风槽和高原槽、低涡、冷锋、青海湖锢囚锋以及中尺度低压、青海热低压、切变线与辐合线、中尺度云团等系统是高原东北部地区大到暴雨的主要相关系统。 100hpa上的南亚高压中心强度加强，位置东西摆动预示高原地区将有降水产生，中心强度减弱，降水过程结束。南亚高压西部副型是高原东北部地区大到暴雨的主要流型。 | | 4. | The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th , june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa , subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average , this is the rainy season for the south of china , but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability , but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain
作为对比，本文还对2002年6月24 - 25日发生在北京地区的强地形雨进行了分析，并讨论陕南、北京地区两地暴雨的异同点以及地形作用的共性和个性，为两地暴雨预报提供有益的参考，得出了一些很有意义的结果： 1大尺度环流背景分析表明： ( 1 ) “ 02 . 6 ”强降水与6月上旬越赤道气流和季风爆发密切相关，携带大量水汽的偏南气流与冷空气于6月8日交汇在西北地区东部，导致了这次强降水的发生； ( 2 ) 200hpa的副热带西风急流、 500hpa副高以及850hpa的低空急流的配置非常有利于本文分析之陕西强降水的发展与维持。大尺度形势分析表明，东高西低形势场、低空急流的建立和高低空形势的配置决定了这场降雨出现在西北地区东部。与暴雨区相联系，存在一支横越低空急流的经向垂直环流，暴雨区处于该垂直环流的上升支； ( 3 )偏南和偏东气流水汽通道在西北地区东部交汇，水汽的辐合积聚主要在对流层低层和行星边界层内完成； ( 4 )整层的视热源< q _ 1 >高值区在暴雨区附近呈东北-西南向分布，与切变线走向非常一致，降水产生的凝结潜热释放是强降水区大气的主要热源。 | | 5. | The first diagnostic analyses show that the heavy rainfalls are produced together by vortex , shear line and upper and lower jets , meiyu front . the condition of high energy , saturation , potential instability is propitious to the form and maintenance of heavy rainfall . the result of numerical simulation by mm5 model shows that heavy . rainfall has close relation with meso - scale vortex pole and strong convection
采用ncep全球谱模式和常规观测资料对“ 03 . 7 ”江淮地区的两次暴雨过程的影响系统及其可能机制进行了初步诊断分析，发现梅雨暴雨是受低槽、低涡、切变线、高、低空急流和梅雨锋区共同影响造成的，该地区维持高能、饱和、潜在不稳定的环境，有利于暴雨的产生中尺度数值模式( mm5 )模拟结果表明梅雨暴雨与中尺度涡柱、强对流运动密切相关。 |
