| 摘 要： | 本文根据1989年4月10～21日在东海东北部的海洋调查资料以及1989年4月10日和16日的卫星红外影象分析了黑潮锋面涡、暖丝和暖环的特征.结果表明,出现在这里的锋面涡约以30cm/s 的速度随黑潮主干移动,在锋面涡的冷中心区陆架混合水插入同时,下层的高营养水上升,从而造成高生产力区.黑潮暖丝携带约4×10~6m~3/s 的输运量以50 cm/s 的速度逆黑潮西行,然后暖丝可能沿陆架坡转向北,或可能顺时针旋转形成暖环.

| Abstract: | Characteristics of the Kuroshio frontal eddy,warm filament and warm ring are analysed ac- cording to the oceanic investigation data obtained in the northcast East China Sea during 10 to 21 April,1989 and the satellite infrared images on 10 and 16 April,1989.The results show that the frontal eddy occurring in the area moves at a phase speed of about 30cm/s with the Kuroshio mainstream.The intruding of the shelf mixing water and the upwelling high nutrient water of the low layer in the cold core region of the frontal eddy result in a high productivity area.The warm filament moves westward opposite to the Kuroshio at a speed of 50 cm/s and then it moves probably northward along the continental slope or rotate clockwise to form a warm ring. |
