【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 high-resolution tidal numerical model of Haizhou Bay and its outer sea area is established by using the FVCOM (finite volume coast and ocean model) model of ocean dynamic model. The time series of astronomical tide values at all grid points in the field are extracted. The water level correction model is extracted from the data of five tidal stations distributed in this area, and the grid points in the field are modified to obtain the high precision time series of grid water level, and then the water level values before and after the correction are compared. The results show that the accuracy of tidal level numerical simulation based on water level correction is improved by about 10 cm.
