摘　　要：根据海洋调查历史资料 ,对台湾东北海域冷水块的时空分布、结构、特点进行分析 ,主要结果如下 :(1 )首次利用卫星跟踪漂流浮标的轨迹 ,佐证冬季该冷水块的存在。 (2 )鉴于该冷水的重要性 ,建议对它给予称谓 ,暂定名为“彭花棉”冷水块。 (3 )该冷水块是黑潮次表层水涌升的结果 ,是黑潮对我国近海海洋环境影响的典型实例之一。 (4)该冷水块具有低温、高盐、高密、低氧、高磷。Based on the historical marine observational data, the characteristics, structure and space-time distributions of the cold water body in the sea area northeast of Taiwan are analysed, and the main results are as follows. (1) The existence of the cold water body in winter was first verified by using the satellite tracked drifter trajectories. (2) In view of the importance of the cold water body, it is suggested to name the cold water body 'Penghuamian' cold water body. (3) The cold water body results from the upwelling of subsurface Kuroshio water, which shows the influence of the Kuroshio on the Chinese marine environment. (4) The cold water body is characterized by low temperature, high salinity, high density, low dissolved oxygen, high phosphate, high silicate and high nitrate.
