By using ncep / ncar reanalysis data of height and wind, the inter - monthly lpac map, the climate lapc map, inter - annual anomaly map and mean variance map of monthly wind field of 850 and 500hpa and monthly height field of 850, 500, 150, 30hpa are calculated in a globe - belt area, which situates between 30 s and 75 n, from december 1957 to december 1997, according them we analysis the rule of the season transfer and anomaly of nh mean circulation. the results show that the climate map of lapc can describe the seasonal transfer process of large scale circulation better. the advance process of summer circulation establish is form south to north at the middle and lower level of the troposphere, that is reflected primly in the inter - monthly wind and pressure map of lapc ; at lower lever of stratosphere, the establish process is simulate to that of troposphere, and reflect of process of that the south asia high toward plateau ; at middle stratosphere the summer circulation establish begins at middle and high latitude initially, and then transmits to low latitude gradually, while the seasonal variability in mid - stratosphere is stronger than it in troposphere and low - stratosphere
利用ncep ncar再分析高度場和風場資料，計算了30 s 75 n球帶區域1957年12月至1997年12月逐月850 、 500hpa風場及850 、 500 、 150 、 30hpa高度場月際局地型相似系數圖、多年平均圖（即氣候lpac圖） 、年際異常圖及均方差圖，在此基礎上，分析了北半球平均環流季節轉換及其異常的規律。分析表明，氣候局地型相似系數圖較好地給出了大尺度環流季節轉換發生的過程：在對流層中、下部，風、壓場月際局地型相似系數圖清楚地反映了夏季型環流建立由南向北的推進過程；低平流層夏季型環流的建立與對流層接近，其中，南亞高壓上高原過程有明顯反映：中平流層，夏季型環流的建立明顯表現為從中、高緯度開始，逐步向低緯傳播的特徵，且變化較對流層和低平流層明顯。 -
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日發生在北京地區的強地形雨進行了分析，並討論陜南、北京地區兩地暴雨的異同點以及地形作用的共性和個性，為兩地暴雨預報提供有益的參考，得出了一些很有意義的結果： 1大尺度環流背景分析表明： （ 1 ） 「 02 . 6 」強降水與6月上旬越赤道氣流和季風爆發密切相關，攜帶大量水汽的偏南氣流與冷空氣於6月8日交匯在西北地區東部，導致了這次強降水的發生； （ 2 ） 200hpa的副熱帶西風急流、 500hpa副高以及850hpa的低空急流的配置非常有利於本文分析之陜西強降水的發展與維持。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在西北地區東部。與暴雨區相聯系，存在一支橫越低空急流的經向垂直環流，暴雨區處于該垂直環流的上升支； （ 3 ）偏南和偏東氣流水汽通道在西北地區東部交匯，水汽的輻合積聚主要在對流層低層和行星邊界層內完成； （ 4 ）整層的視熱源< q _ 1 >高值區在暴雨區附近呈東北-西南向分佈，與切變線走向非常一致，降水產生的凝結潛熱釋放是強降水區大氣的主要熱源。 -
