  • 黑潮是北太平洋的西方邊界流,屬於北赤道洋流碰到西邊界陸地後向北的分支,途中經過菲律賓東岸、呂宋海峽後,再沿著東台灣通道繼續往東北流。在流經呂宋海峽時,有時會發生入侵至南海的情形。透過分析AVISO衛星資料發現,黑潮在呂宋海峽的入侵現象,存在著季節變化,當冬季東北季風強盛時,黑潮較常被發現到會入侵至南海內部,而西南季風盛行的夏季期間,並未發現有入侵的情況。
      本研究透過模式試驗,發現黑潮入侵南海的現象與臺灣西南邊的風應力旋度有關。冬季時,臺灣西南邊負的風應力旋度轉為強烈,黑潮會明顯偏向西側,進而入侵至南海。反之,夏季時,臺灣西南邊的風應力旋度微弱甚至消散,黑潮則會沿著呂宋海峽東側一路向北前進,並未入侵至南海。
      進一步將臺灣西南邊(119.5。E~121。E、21。N~22。N)的風應力旋度,與黑潮入侵至南海所流經區域(120。E~122。E、21。N~20.5。N)之動能計算其相關性,得到的相關係數達0.67,呈現顯著正相關,再次證實,臺灣西南邊的風應力旋度與黑潮入侵南海存在著密不可分的關係。
