| 摘 要： | 利用粤西海域高频地波雷达观测得到的表层海流资料进行潮流调和分析。结果表明: 粤西近海主要属于不正规半日分潮, 浅水分潮较强。以M2分潮为例, 潮流运动形式主要为逆时针的往复流为主, 方向沿西北—东南方向。粤西近海的潮能主要由东部陆架输送进来, 潮能自东向西传播, 在大潮期间, 粤西的潮能出现向岸方向分量, 表现为从东南向西北方向传播, 在近岸区域潮能通量传播的方向会发生一个向岸的偏转。通过潮能收支方程计算潮能耗散, 发现粤西近海潮能耗散的高值区在西部岛屿密集区域, 与琼州海峡的存在和琼州海峡东北处地形变化存在明显的相关关系。

| Abstract: | We study the characteristics of tidal current on the west coast of Guangdong Province using the surface current data observed by a High Frequency Ground Wave Radar (HF radar). Tidal harmonic analysis results show that the tide in this area mostly belongs to irregular semidiurnal tide, and the shallow water components are not negligible. The M2 tidal current is mainly counterclockwise reciprocating flow. The direction is along the northwest-southeast. In the near-shore region, tidal energy flux spreads to the shore. The tidal energy flux is from east to west in the east part of the study area. Through tidal energy budget analysis, we found that high dissipation appears in the west part of the study area, which has a lot of islands there is related to the existence of the Qiongzhou Strait and the topography on the west coast of Guangdong Province. |
