摘要
依据2004年在舟山灌门水道及邻近海域获取的同步潮位和潮流资料,对该海域的潮波特性进行了统计和分析,并对分析过程中发现的主要半日分潮经过灌门水道时振幅有较大幅度减小的现象进行了初步研究,认为截面积急剧变化的水道,潮波势能向动能的转换是产生主要半日分潮振幅减小的一个重要因素。这一结论或许有助于解释M2分潮波通过舟山群岛海域振幅明显减小的现象。
According to the hydrological data obtained in Guanmen channel and its neighborhood in Zhoushan in year 2004, the characteristics of tides in the zone are analysed, and the cause of semidiurnal tidal amplitude decrease during tidal transit of Guanmen channel is discussed. It is conclude that in the varying cross-section channel the exchange from potential energy to kinetic energy plays an important role in making the semidiurnal tidal amplitude decrease. This conclusion may be also helpful to explaining the reason why the amphtude of M2 constituent decreases when thansiting from Zhoushan archipelago.
