mid-latitude cyclone
解釋
鋒面氣旋-
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。 -
( 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。
