在这项工作中,地下流计数据将被同化成威德尔海潮汐流的二维和三维数值模型。逆方法将用于指导改进日涡度波和底部边界层摩擦效应的参数化。由于威德尔海靠近主要半日潮的临界纬度,分层作用弱,底层边界层厚,潮流相对正压,简化了建模任务,可以更好地利用海流表表征流。
英文摘要
9908091Padman/EgbertIn this work, sub-surface current meter data will be assimilated into two and three-dimensional numerical models of tidal flows in the Weddell Sea. Inverse methods will be used to guide improvements of parameterizations of the effects of diurnal vorticity waves and of friction in the bottom boundary layer. Since the Weddell Sea is close to the critical latitudes for the main semi-diurnal tide and has weak stratification, the bottom boundary layer is thick and the tidal flow is relatively barotropic, simplifying the modeling task and allowing a better characterization of the flow by the current meters.
