太平洋海溫異常對北半球大氣環流異常有重要影響,而enso循環是太平洋海氣耦合系統中典型的異常演變過程,不僅描述了熱帶地區大氣和海洋異常現象,而且與中高緯度的氣候異常變化相聯系。It also explain that the correlation between ssta of kuroshio and the change of wind field in equaroral mid - pacific is results of air - sea interaction ; however, when time comes into summer, the instance status of ocean is different from the last winter to next early springtime, the sea surface temperature turn into the definitive factor, so the increase of heat flux in may to jun month which is realized by absorbing more heat from the sun radiation results in the decrease of sst in kuroshio in the season of jun - jul. finally, during the aug to dec season of next year, the sst of kuroshio is increasing again
最後分析了黑潮海溫與夏季東亞大氣環流及我國降水的時滯關系,發現:當前冬黑潮區域海溫異常偏高時,後期夏季亞洲低壓的強度減弱,西北太平洋副熱帶高壓強度加強,而且位置西伸、偏北,梅雨鋒位置偏南,長江中下游地區降水偏多,北太平洋冬季海域的海溫分佈呈+ 、 - 、 +趨勢(順序為赤道中東太平洋、西北太平洋、我國近海) ;反之亦然。When the wpi - soi correlation is weak and the west pacific sst warmer ( colder ), a anomalous anticyclonic ( cyclonic ) circulation is found in the lower troposphere over northern equatorial western pacific. this anomalous circulation is not in favor of maintaining a significant correlation between the west pacific sst and enso
Wpi - soi相關關系微弱時,在西太平洋赤道北側的對流層低層存在高(低)海溫?反氣旋(氣旋)異常環流系統,不利於維持enso與西太平洋海溫變化間的緊密聯系。Based on the epwp and wpwp in conjunction with abnormal north and west wind, a new possible iii mechanism is provided for the evolution of the 1997 / 1998 el nino. to be specific, the warm kelvin wave propagating to east excited by the abnormal west wind can suppress the cold upwelling flow in the eastern pacific, which, in turn, is favorable to the eastern pacific sst increase ; abnormal west wind can make the warm water of the wpwp east edge extend to east, which is conductive directly to eastern pacific sst increase ; the abnormal west wind propagating to east can make the sea surface warm water near two equatorial laterals converge to the equator by ekman drifting, which, in rum, strengthens the downwelling flow near the equator, leading to eastern pacific sst increase
將東、西太平洋暖池及異常北風、西風一併結合起來考慮,提出1997 1998elnino事件發生、發展的一種新的可能機制:異常西風激發東傳的暖kelvin波對東太平洋的冷上翻流有抑制作用,從而有利於東太平洋海表溫度增加;異常西風驅動西太平洋暖池東端暖水向東伸展直接有利於東太平洋海表溫度增加;東傳的異常西風可以通過埃克曼漂流效應將赤道兩側的海表暖水向赤道輻合從而加強了赤道附近的下沉流,也有利於東太平洋赤道附近海表溫度增加。Further, correlation analysis is used to the summer rainfall and four seasonal north pacific ssta, the results suggest north pacific ssta which notability cause the summer rainfall anomaly over eastern china are prophase winter ssta of kuroshio region of northwestern pacific, prophase spring ssta of middle and eastern equatorial pacific and summer ssta of west wind drift region

其區域性形成的原因主要可能是因為各海區對冬季風異常的響應方式不同,強冬季風使得黑潮與我國近海海洋過多散熱,海溫降低;在西北太平洋暖池北部,強冬季風引起西風異常,從而引發異常氣旋性環流,海水輻合下沉加熱其表層以下海水,同時異常環流使得更多東側異常暖水向西加熱其表層水;在黑潮與親潮交匯處的升溫也主要是由於強冬季風導致的流場異常,海水輻合下沉升溫。( 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
