摘要
本文建立了一种适应POM模型特点的干湿点数值处理方法,将其镶嵌于二维POM模型中用以模拟泉州湾的潮汐潮流,两个站点上的模拟结果与实测数据吻合较好。计算结果还显示:泉州湾的潮汐潮流均以半日潮为主;除在湾口中部呈现出较强的旋转流外,湾内大部海域以往复流为主;另外,计算得到的泉州湾内平均潮差约为4m,如此大的潮差是导致湾内浅滩和暗礁在落潮时干出、涨潮时重新被漫过的根本原因。
A wetting and drying scheme fit to POM is designed and incorporated into the two dimensional model to simuolate tides and tidal currents, and the modeled results agree well with the data observed on two moored ship stations. Our modeled results also show that the semi-diurnal tides and currents are dominant in Quanzhou Bay; except in the center of open boundary of the researched area where rotary currents are marked, most sea areas are characterized by rectilinear to and-fro current ; besides, the large tidal range with a mean value of 4 m is responsible for the alternate wetting and drying of shoals and submerged rocks during the flood and ebb, respectively.
