摘要: 利用海洋动力模式FVCOM(finite volume coast and ocean model)模式建立了高分辨率的海州湾及其外海域潮汐数值模型,提取了整个场内各个网格点上天文潮位值的时间序列。利用该区域内分布的5个验潮站资料提取水位修正模型,对场内的网格点进行水位修正,得到高精度的格点水位时间序列,然后对修正前后的水位值进行比较。结果表明,基于水位修正后的潮位数值模拟结果水位精度提高了10 cm左右。

Abstract: The finite volume coastal ocean model (FVCOM) has been applied to establish a high-resolution numerical model of tide in Haizhou Bay. The time series of astronomical tidal values at each grid point are extracted. The water level correction model is used to extract the water level correction data from the five tide station data in this area, and the water level of the grid site is corrected. The water level time series of the grid is obtained with high precision, then the modified water level value is interpolated. The instantaneous sea surface height is obtained at a certain time. The results show that the water level accuracy is improved by about 10 cm based on the numerical simulation of water level correction and the sea surface height model has been improved obviously.

Key words: FVCOM, tidal numerical simulation, residual water level
