Numerical Simulation of Tides and Tidal Currents in Jiangsu Offshore Areas, China

摘要

A numerical model suitable for tides and tidal currents forecast in Jiangsu offshore areas, China, which includes M2, S2, K1, and O1 tidal constituents, is developed based on the Estuarine and Coastal Ocean Model with semi-implicit scheme (ECOM-si). Comparing the computed values with those of 6 tidal observatories and 12 current stations, the results also show a good agreement.Based on these results, the isoamplitude and the cotidal lines of the main constituents M2 and K1 are given. It is found that semi-diurnal tide constituents M2 has tide-free point and diurnal tide constituents K1 has no tide-free point in this area.
