As a result, we find that in winter when the kuroshio is cooler than the normal, at following summer, the continental cyclone deepen and the east asia monsoon strengthen, that the mid - latitude blocking high weaken and zonal circulation develop, the east asia teleconnection of " - + - " is stired up, so that subtropical high weaken and diminish, and tend to east north, tropical monsoon trough strengthen and mei - yu front weaken, and tend to north, meanwhile south asia high weaken and diminish, and tend to eastvnorth, is easy to form eastern region type
結果發現當黑潮海溫冷異常時，後期夏季大陸熱低壓加深，東亞夏季風偏強。中緯度阻塞高壓減弱，東亞地區緯向環流發展，在東亞-西太平洋地區激發「 - + - 」的東亞遙相關型，從而西太平洋副高強度偏弱，面積偏小，位置偏東、偏北，東亞梅雨鋒也偏弱，季風槽則變強，位置偏北。同時南亞高壓偏弱，位置偏北、偏東，易形成東部型。 -
To the large - scale atmosphere, we separate the terms of the horizontal vorticity converting into the vertical vorticity, which considered as the baroclinic terms, from the terms that not including horizontal vorticity by the rules of the p coordinate transforming to the z coordinate in the traditional vorticity equation, and carry out the scale analysis, and then conclude that the baroclinic terms are able to reach the same magnitude grade as the partial derivative of the vertical vorticity to time when it takes place the large scale precipitation in the summer monsoon period in china. by analyzing the game reanalysis data from april to august in 1998 in the region of chinese continent, we found that the baroclinic terms is important to the large - scale cyclone developing above the 600hpa, and the magnitude changing of the baroclinic terms is nearly in - phase as the monsoon movement, so which imply exactly that the magnitude changing of the baroclinic terms is the one of the natural characters of the summer monsoon evolution and equivalent to the movement rule of the subtropical high of the western pacific
在p坐標垂直渦度方程中，利用p坐標向z坐標轉換的公式將水平渦度向垂直渦度轉化的所有項分離出來，這些項具有明顯的斜壓特徵，對其進行尺度分析后，得出在可以忽略潛熱釋放對渦度影響的對流層中、高層，此轉化項是大尺度斜壓渦度發展的重要項。通過對1998年48月的game再分析資料進行實際計算也發現，轉化項在東亞夏季風上升支的600hpa及以上層次對垂直渦度的局地變化貢獻很大，不能忽略。同時發現水平渦度向垂直渦度的轉化在南海季風爆發時和江淮梅雨入梅及發展過程中均有指示性意義，在南海季風爆發以後，在中國東南部地區，轉化項的大小與夏季風的活躍和中斷等活動有著幾乎一致的變化規律，這從側面也指出了，此轉化項的變化是夏季風演變所具有的本質特徵，並且它反映出了西太平洋副高在中國大陸的活動情況。 -
( 4 ) in summer, tropic west pacific ssta decadal change infect precipitation decadal change in south and north of changjiang river maybe by : positive ssta in tropic west pacific weaken the summer monsoon circulation, lead more precipitation in south of changjiang river and less precipitation in north of it, vice versa ; middle north pacific ssta decadal change infect precipitation decadal change in mid - down valley of changjiang river maybe by : when ssta is negative in middle north pacific, the height field in tropic rises obviously, the subtropical high strengthens and extends westward, the northern limit retreats southward, leads upper trough retreats northward and move eastward, meiyu front moves northward, then leads more precipitation in mid - down valley of changjiang river, vice versa ; middle northwest pacific - low latitude mid - east pacific infects precipitation in north china possibly by change the activity of northeast china cyclone
（ 4 ）熱帶西太平洋ssta年代際變化影響夏季中國長江南北降水年代際變化的可能機制是熱帶西太平洋海表溫度正（負）異常減弱（加強）東亞夏季風環流，從而使江南降水增加（減少） ，江北降水減少（增加） ；夏季中部北太平洋ssta年代際變化影響中國長江中下游地區夏季降水年代際變化的可能機制是中部北太平洋海表溫度負異常，將導致熱帶地區高度場普遍增高，副高加強西伸，副高北界南退，致使高空槽北縮東移，梅雨鋒西移北進，中國長江游中游、中卜游降水增多，反之亦反；夏季中高緯西北太平洋一低緯中東太平洋反向距平分佈結構影響中國東北降水的可能機制是低緯中東太平洋海表溫為負異常。 -
Firstly, subtropical high center lay to the north than usual, and forms a blocking high in combination with land high in eastern asia. secondly, on account of the strong southwest current which occurred at the west side of the subtropical high and dynamic effect of the typhoon itself, the landing northward tropical cyclone ( 9711 ) landed in liaoning again. thirdly, a trough with some weak air from ural mountain and the northeast cold air entering into the tropical cyclone showed that the systems in different latitudes had some effects each other
模擬結果表明：此次熱帶風暴造成遼寧全省大暴雨的天氣背景是：副熱帶高壓偏北並與大陸高壓疊加，構成了穩定的東亞阻塞形勢； 9711臺風減弱的熱帶風暴，在其自身內力和副高西側的強盛偏南氣流引導下，持續北上並在遼寧營口至盤錦之間登陸；從烏拉爾山冷堆分裂南下出的弱冷空氣不斷南下，與熱帶風暴在遼寧產生了相互作用，增強了上升運動，致使大暴雨出現。
