日潮特征海域回归潮平均高高潮位的计算方法

An Algorithm for Calculating Mean Higher High Water of Tropic Tide at Diurnal Tide Sea Waters

针对海岸线定义不适用于日潮特征海域的问题,分析了不同潮汐类型海域潮汐高潮位与月相和月赤纬间关系,提出并实现了日潮特征海域顾及日潮龄值的回归潮平均高高潮位计算。结果表明,在不规则日潮海域月赤纬极值与回归潮高高潮位表现出强相关性。海岸线定义明确为平均大潮高潮面或回归潮平均高高潮位与海岸的交接线更科学。

Aimed at the problem that the definition of the coastline currently does not apply to diurnal tide sea waters, the relationship between the tide high water and the phase of the moon as well as the declination of the moon are analyzed at different tide type areas.The calculation of the mean higher high water of the tropic tide considering the diurnal tide age at diumal tide sea waters is proposed and realized.The result shows that there is a strong correlativity between the extremum of the declination of the moon and the higher high water of the tropic tide at the irregular diumal tide waters.The definition of the coastline should be modified as the connection line between the coast and the mean high water spring or the mean higher high water of the tropic tide.
