   視熱源、視水汽匯的變化和暴雨的演變之間存在較強(qiáng)的耦合，兩者的極值出現(xiàn)的時間十分一致；垂直平流項是視熱源、視水汽匯三個分量中的主要貢獻(xiàn)者。
2. 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
   作為對比，本文還對2002年6月24 - 25日發(fā)生在北京地區(qū)的強(qiáng)地形雨進(jìn)行了分析，并討論陜南、北京地區(qū)兩地暴雨的異同點以及地形作用的共性和個性，為兩地暴雨預(yù)報提供有益的參考，得出了一些很有意義的結(jié)果： 1大尺度環(huán)流背景分析表明： ( 1 ) “ 02 . 6 ”強(qiáng)降水與6月上旬越赤道氣流和季風(fēng)爆發(fā)密切相關(guān)，攜帶大量水汽的偏南氣流與冷空氣于6月8日交匯在西北地區(qū)東部，導(dǎo)致了這次強(qiáng)降水的發(fā)生； ( 2 ) 200hpa的副熱帶西風(fēng)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陜西強(qiáng)降水的發(fā)展與維持。大尺度形勢分析表明，東高西低形勢場、低空急流的建立和高低空形勢的配置決定了這場降雨出現(xiàn)在西北地區(qū)東部。與暴雨區(qū)相聯(lián)系，存在一支橫越低空急流的經(jīng)向垂直環(huán)流，暴雨區(qū)處于該垂直環(huán)流的上升支； ( 3 )偏南和偏東氣流水汽通道在西北地區(qū)東部交匯，水汽的輻合積聚主要在對流層低層和行星邊界層內(nèi)完成； ( 4 )整層的視熱源< q _ 1 >高值區(qū)在暴雨區(qū)附近呈東北-西南向分布，與切變線走向非常一致，降水產(chǎn)生的凝結(jié)潛熱釋放是強(qiáng)降水區(qū)大氣的主要熱源。
