摘要:

根据2016年春、夏、秋、冬季海口湾海域实测海流全潮实测资料,分析了海口湾潮流的季节性变化特征。结果表明:① 该海域春、夏、秋季潮流特征为不正规全日潮流,冬季潮流特征为不正规半日潮流;② 靠近岬角位置的海域,由于涡旋作用更容易表现出半日潮流特征;③ 该海域潮流主要以主太阴半日分潮M2、太阴太阳赤纬全日分潮K1和主太阴全日分潮O1分潮流为主,并且3个分潮大小接近;④ 该海域冬季从东向西水体输运最强烈;⑤ 春、夏、冬季该海域有产生中底层补偿流,秋季没有出现明显的补偿流。

Abstract:

The seasonal variations of tidal currents in the Haikou Bay are analyzed based on the obtained data in 2016. The results demonstrate that: (1) the irregular diurnal tides were observed during spring, summer and autumn, while the irregular semi-diurnal tides were obtained in winter. (2) Because of the eddy influence, it is easier to obtain the irregular semidiurnal tidal currents near the cape area. (3) The tidal currents are mainly M2, K1 and O1, and their constituents are similar. (4) The strongest water transportation is from east to west in winter. (5) In this area, there are compensation currents during spring, summer and winter, while no obvious compensation currents could be obtained in autumn.

Key words: the Haikou Bay, tidal current, residual current, water transportation
