    結果表明：此次霍山暴雨發生前後，存在明顯的大強度低空急流，並受到中尺度切變線的影響，而且正渦度的加強引起了輻合加劇，提高了上升速度從而引起降水，同時暴雨發生前螺旋度的迅速增強，也為預報提供了根據，另外水汽通量的輻合以及分析位渦反映出的斜壓對流不穩定都充分體現了這次降水的特點。
  2. The magnitude of these variables increased approximately ten times. it helped the rapid releasing of instability energy. the interaction of high - level and low - level mesoscale system leads to the rainstorm. the vertical cross section analysis of potential temperature tells us that rainstorm take place in the warm - moist and instability area. usually locate in the very stiff moist isentropes and it can lead to the development of vortex

    通過對相當位溫的垂直剖面分析，可知兩場暴雨的中低層都為暖濕不穩定區，暖濕不穩定區上部冷空氣明顯擴散，暴雨產生在暖濕對流不穩定區內，通常產生在_ e陡峭和密集區中， _ e陡峭和密集區有利於渦旋發展。
  3. The effect of bengal gulf though to the abnormal precipitation of south of jiangsu is all strong, but it is all weak to the abnormal precipitation of north of jiangsu during the 1st. - 7th

    五一、十一期間兩區連陰雨、連晴天氣與低層渦旋系統的10一20天振蕩都有著很好的對應關系。
  4. In 1999, the dipole existed in between the okhotsk high and the depression in the north of northeast china, thus the okhotsk high became active and maintained, the subh was located to an area quite further south than usual. the high persisted in the east region of nw china, the cold air flowed to the mid - lower reaches of the yangtze river along the high. in the east region of nw china, air steam under troposphere was strong sinking motion, and formatted the negative vorticity region, the vapour flux divergence was divgence. lt was apparently that the rain could n ' t occur in the eastern portin of nw china. in 2000 year, okhotsk high was very weak or did n ' t exist in, there was high in the east asia - japan, the subh is located to an area further north than usual. in the east region of nw china, the trough maintained, air stream under troposphere was strong ascending motion, the cycolonic circulation was prevailing, the vapour flux divergence was intensive convergences the rain easy happened in the east areas of northwest china

    4多梅雨1999年鄂霍茨克海阻塞高壓與我國東北北部低壓形成偶極子，使得阻塞高壓穩定少動，西太副高位置偏南，西北地區東部持續受高壓控制，冷空氣沿此高壓流經長江中下游地區上空；在西北地區東部對流層中下層氣流下沉運動較強，呈反氣旋渦度，水汽通量散度輻散，不利於西北地區東部降水。空梅雨2000年相反，鄂霍茨克海高壓減弱甚至不存在，東亞-日本為高壓，西太副高位置偏西偏北，西北地區東部處于西風槽中，對流層中下層氣流上升運動增強，盛行低壓環流，水汽通量散度強烈輻合，有利於降水生成。
  5. The analysis of dry pv shows that the high pv dominate the area of typhoon, the higher is the center value of pv, the stronger is the typhoon. lt is also shown that the most important reason resulting in rainstorm is the cold air ( high pv ) which spreads to south from the upper troposphere or lower stratosphere and transports into the warm air. the joining situation of upper and lower pv area make vortex develop. pv transpotation reduces static stability, which increases the releasing of instability energy and makes rainstorm amplify

    對干位渦的分析表明：臺風或臺風環流區為高值位渦區，臺風越強，位渦中心值越大；對流層上部或平流層下部冷空氣（高位渦）的擴散南下與暖濕氣流的交匯是造成特大暴雨的重要原因，因為上游斜壓性的發展使對流層頂發生折疊，平流層與對流層相互作用增強，上下位渦區相接的形勢使低層渦旋發展，上升運動加強，位渦的下傳有效地降低了靜力穩定度，有利於位勢不穩定能量的釋放，使得暴雨增幅。
  6. By mesoanalysis of a precipitation that occurred in the middle reaches of the changjiang river, 8th jul. in 2003, the formation and development of the event, its relation with the meso - microscale system are studied, it is emphasized that the low - level jet would cause favorable thermodynamic, moisture and dynamic conditions for the heavy rainfall in the middle reaches of the changjiang river and that the mesoscale vortex formed in the left of the low - level jet would stimulate strong convective clouds and cause the heavy rain

    摘要通過對2003年7月8日發生在長江中游的一場大暴雨進行中尺度分析，初步研究了暴雨的形成及發展過程，總結了暴雨的產生與中小尺度系統的關系，著重闡述了低空急流在暴雨形成中的作用，以及在低空急流左側強正渦度中心附近形成中尺度渦旋，激發暴雨雲團等。
  7. The hong kong observatory has recently developed a rainstorm nowcasting system called swirls ( short - range warning of intense rainstorms in localized systems ) to forecast rainfall in the territory up to 3 hours ahead

    香港天文臺近年致力開發一套預測未來一至三小時香港境內降雨情況的暴雨臨近預報系統（ swirls - short - rangewarningofintenserainstormsinlocalizedsystems ） ，簡稱小渦旋。
  8. Apart from the above weather stations, meteorologists from the three places also established over the years the exchange of real - time weather information through dedicated data lines, the networking of weather radar data from the area, and the closer consultation among forecasters in these places during the approach of severe weather. currently in progress is the expansion of swirls ( short - range warning of intense rainstorms in localised systems ), developed by the hong kong observatory, to a rainstorm forecasting system covering the pearl river estuary

    除上述氣象站外，三方的氣象人員多年來還實現了利用專用數據線路交換實時氣象資料、將三地的天氣雷達數據聯網、以及加強了三方預報員進行重要天氣評估的磋商等。目前正開展工作，以香港天文臺開發的小渦旋暴雨臨近預報系統為基礎，致力擴展成一套覆蓋整個珠江三角洲的暴雨預報系統。
