基于有限体积法海洋数值模型（FVCOM ），构建了温州近海潮汐潮流数值模式，模式模拟区域为（120°24′00″～121°19′12″E ，27°21′00″～28°24′00″N ），模式水平分辨率由近岸河口区的50 m ，逐渐增加至开边界附近的2 km。模式模拟并分析了温州近海的M2，S2，N2，K1，O1五个主要分潮。利用温州近海实测资料对模拟结果进行了验证，模拟与实测符合良好；其中与4个验潮站资料比较，M2，S2，N2，K1，O1五个主要分潮的振幅绝均差和迟角绝均差分别为4．84 cm和5．14°，2．19cm和3．35°，5．18cm和4．38°，0．64cm和3．67°，0．59cm和4．61°；与9个海流连续观测站比较，流速绝均差为11．71 cm／s ，流向绝均差为9．66°。在模拟结果较好地反映温州近海潮汐、潮流运动状况的基础上，本文给出了各模拟分潮的潮汐同潮图和潮流椭圆分布、潮汐和潮流类型分布以及最大可能潮流分布等。%Based on the finite‐volume coastal ocean numerical model (FVCOM ) ,a tidal model is established for the Wenzhou offshore .The computational domain covers (120°24′00″~121°19′12″E ,27°21′00″~28°24′00″N) .The horizontal resolution is 50 m at the near shore and increase to 2 km gradually .Five principal tidal constituents ,M2 ,S2 ,N2 ,K1 and O1 ,are simulated and analyzed .The model results are compared with observation ,showing a satisfactory agreement .Comparing with 4 tidal gauge stations ,the mean ab‐solute difference in amplitude and phase‐lag are respectively 4 .84 cm and 5 .14° for M2 ,2 .19 cm and 3 .35° for S2 ,5 .18 cm and 4 .38° for N2 ,0 .64 cm and 3 .67° for K1 and 0 .59 cm and 4 .61° for O1 .Comparing with 9 currents observation stations ,the mean absolute difference in speed is 11 .71 cm/s and the mean ab‐solute difference in direction is 9 .66° .Based on model outputs ,the distributions of co‐tidal charts ,tidal current ellipses ,tide and tidal current types ,and the maximum possible tidal current ,are given .
