結果表明： （ 1 ）華北夏季降水異常與同期印度低壓、西太平洋副高、中緯度西風槽脊、南亞高壓、副熱帶季風環流和冷空氣活動的異常都密切相關。華北夏季降水異常年春季的環流特徵與夏季類似。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。The results show that the heavy storm was caused by the interaction between a tropical cyclone trough that landed in guangdong province and a weak cool front in the westerlies

3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。( 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。Concentrations of total suspended matter ( ctsm ) is unanimous with observational data and other scholars " researching results. the distribution of ctsm is higher along coast than other areas there is a tongue - like zone with high ctsm from north to southeast. the transport simulation result reveals that sm can spread to the okinawa trough for enough sea water mixing in winter. but in summer. sm can not traverse the big water barrier of kushino for different circulation character. this difference is probably related to the shifting n - s monsoon
懸浮體輸送表明，在冬季，懸浮體除了在陸架上發生擴散外，由於海水的強烈混合作用和環流的季節性變化，部分中、底層懸浮體可擴散至沖繩海槽甚至西太平洋;在夏季，由於海水層化及夏季環流特徵，懸浮體基本不能穿越黑潮這一水障，這一差異可能是由於季風和不同環流特徵所引起的。( 4 ) flood season precipitation anomalies has a good correlations with southwest and southeast summer monsoon, polar vortex, west wind trough and west pacific high ( 5 ) the ssta anomalies of west pacific key regions combine with south atlantic key regions has a good predict to the flood season precipitation anomalies in liaoning areas
遼寧夏季多雨水汽來源於西南夏季風和我國東部海域，汛期降水異常與西南、東南夏季風，極渦，西風槽以及西太平洋副高活動關系密切。西太平洋和南大西洋海溫關鍵區冷暖水年結合對遼寧汛期多少雨年有很好的指示作用。While the precipitation of southeast of inner - mogolio is attributed as the strong convective precipitation, the rainfall of liaoning and northeast of heilongjiang is induced by subtropical high and westerly trough, and that of west of heilongjiang is influenced directly by vortex in upper air
各區域產生極端降水的天氣背景也不相同：內蒙古東南部的降水是前傾槽引起的強對流降水天氣，遼寧和黑龍江東北部的降水是由於副熱帶高壓和西風槽的共同作用引起的。黑龍江西部的降水是由於高空渦的直接作用引起的。The rsults are as follows : ( 1 ) precipitation shows the decreasing trend and remarkable interannual and interdecadal variations in flood season in the last 44 years. ( 2 ) precipitation anomalies in flood season have a good correlations with southwest and southeast summer monsoon, polar vortex, west wind trough, the subtropical high over west pacific and south asia high
（ 2 ）遼寧汛期水汽來源於西南夏季風和我國東部海域，汛期降水異常與低空的西南、東南夏季風、中空的極渦、西風槽、西太平洋副熱帶高壓活動及高空的南亞高壓關系密切。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。The famous local snacks of xining style include yin liangfen ( bean jelly ), mazhong rangpi, yang lurou, kang zhurou ( pork ), li yangtou, xinsuan chao, wang mianpian ( flat noodle ), meng dadou, wangkewa daoba, song jingdui, liu zongzi ( glutinous rice dumpling ), yangchang zhijia etc., most are very economical

當秋季黑潮區域海溫異常偏高，東亞地區的海陸氣壓差異進一步加大，東亞大槽北部減弱、南部加深、位置東移，東亞地區的偏北風加強，亞洲地區西風環流減弱，即東亞冬季風加強；反之亦然。分享友人
