Impact of ocean currents on mean sea level transfer across seas and its correction
摘要
Abstract
This study investigates the effects of time-varying ocean currents on mean sea level(MSL)transfer and develops a corresponding correction method.The asynchronous effects and error sources associated with the synchronous correction method are analyzed,and a sea-surface-height correction method accounting for time-varying ocean currents is proposed.Using cross-sea tide-gauge stations in the Gulf of Mexico and the North Sea as case studies,the asynchronous effects on sea surface height caused by long-period tidal constituents are examined,and the magnitudes of synchronous MSL transfer errors attributable to the inverse barometer effect and time-varying ocean currents are quantified.The results show that correcting MSL for ocean-current variations based on geostrophic balance improves MSL transfer accuracy by 21.8%to 27.6%.This improvement is comparable to that achieved using a multi-year mean correction for the asynchronous effects induced by long-period tidal constituents.The proposed method provides a feasible approach to improving MSL transfer in regions affected by ocean currents.关键词
