【摘要】：利用海洋動(dòng)力模式FVCOM(finite volume coast and ocean model)模式建立了高分辨率的海州灣及其外海域潮汐數(shù)值模型,提取了整個(gè)場(chǎng)內(nèi)各個(gè)網(wǎng)格點(diǎn)上天文潮位值的時(shí)間序列。利用該區(qū)域內(nèi)分布的5個(gè)驗(yàn)潮站資料提取水位修正模型,對(duì)場(chǎng)內(nèi)的網(wǎng)格點(diǎn)進(jìn)行水位修正,得到高精度的格點(diǎn)水位時(shí)間序列,然后對(duì)修正前后的水位值進(jìn)行比較。結(jié)果表明,基于水位修正后的潮位數(shù)值模擬結(jié)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.
