摘要

摘要在之前的一项研究中，我们通过沿海漂流者的轨迹分析了秋冬季节中国大陆沿海的地表流特征（Yang et al.，2021）。本文是对春季地表电流特性的后续研究。通过2019年4-5月沿海漂流者的轨迹，我们继续分析表面洋流的特征。结果表明：（1）2019年4月，浙江、福建沿海海流总体呈西南向，近海海流总体呈东北向。（2） 2019年5月，28°N以北海域的表层洋流在近岸没有固定方向的情况下速度较小，但在近海速度较大。（3） 2019年4月至5月，浙江沿海的地表洋流变化较大，主要与风场的变化相对应。（4）海岸漂流器是一种有用的仪器，可以更准确地观察近海而非深海的环流系统。

Surface Currents Along the Coast of the Chinese Mainland Observed by Coastal Drifters During April‐May 2019

Abstract We have analyzed the surface current characteristics along the coast of the Chinese mainland in autumn and winter by the trajectories of coastal drifters in a previous study (Yang et al., 2021). This paper is a follow-up study focusing on the surface current characteristics in spring. By the trajectories of coastal drifters in April‐May 2019, we continue to analyze the characteristics of surface currents. It is indicated that: (1) the surface currents were generally southwestward along the coasts of Zhejiang and Fujian, while they flowed northeastward in the offshore area in April 2019. (2) In May 2019, the surface current in the sea area north of 28°N had a small speed without a fixed direction nearshore, but had larger speed offshore. (3) The surface currents along the Zhejiang coast were variable in April‐May 2019, mainly corresponding to the change of wind field. (4) The coastal drifter is a useful instrument to observe circulation systems more precisely in nearshore but not deep ocean.
