摘要

摘要: 根据NOAA卫星红外影像和水文、化学、生物的观测资料,分析了黑潮锋面涡旋中的黑潮水向陆架一侧倒卷,陆架混合水被卷入黑潮,以及深层富营养盐水被泵吸到上层海洋的基本形态。分析表明黑潮锋面涡旋在陆架水与黑潮水的交换中起十分重要的作用。本文对3个锋面涡中的水交换量进行计算得到:卷入到黑潮中的陆架混合水平均为0.44×10⁵m³/s,而进入陆架的倒卷黑潮暖水仅为0.04×10⁶m³/s.对于整个东海陆架边缘,锋面涡作用可使1.8×10⁶m³/s的陆架混合水卷入黑潮。在锋面涡存在情况下,被泵吸到真光层并向陆架方向输运的NO₃-N,其单宽输运量为974μmol/(m·s),而无锋面涡存在时仅为79μmol/(m·s).锋面涡造成的陆架方向的NO₃-N输运量为1.7×10⁵t/a.
