摘要: 使用嵊泗站所布设的地波雷达观测获取的径向流数据, 以及嵊泗、芦潮港、岱山3个潮汐观测站水位资料, 采用两点近似投影方法反演流场全矢量流速, 并用T-Tide程序计算调和常数, 分别计算O1、K1、M2、S2各分潮流速场及迟角场, 并计算各点上的潮能通量及潮能耗散, 得到嵊泗岛以西杭州湾口区域潮能耗散同地形存在良好对应关系, 充分证明了采用地波雷达观测数据进行潮能耗散计算这一方法的可行性, 供相关工作者作进一步研究和讨论.

关键词: 地波雷达, 特征值, 潮汐类型, 潮能通量, 潮能耗散

Abstract: Using the single-point ground wave radar data at Station Shensi and the water level data at three stations at Shengsi, Luchaogang and Daishan, the authors obtain flow vectors from the radial flow velocity of ground wave radar observation, and calculate four sub-tidal harmonic constants (O1, K1, M2 and S2).The tidal characteristics derived from the ground wave radar dataset are well agree with that from the tidal gague data. The authors also calculate the tidal energy flux and tidal dissipation rate. There is a good relationship between the tidal dissipation rate and topography. The study shows a good way to calculate tidal dissipation rate using ground wave radar data.

Key words: ground wave radar, characteristic value, tide type, tidal energy flux, tidal dissipation
