Study on short-range numerical forecasting of ocean current in the East China Sea-Ⅲ Three-dimensional baroclinic anomaly forecasting model and its application

A three-dimensional baroclinic numerical forecasting model for anomaly current field is developed for application in the Bohai Sea and the upper layer of the Huanghai Sea and the East China Sea.All the dynamical variables,including temperature and salinity,can be calculated predictively by using the model.The results of the numerical weather prediction are used as input fields.and various dynamic and thermodynamic boundary conditions are adopted.So,the model can be used as an operational numerical forecasting model for current fields.In this paper,the structure of the model is presented in detail,various tests for the performance of the model are made,and the dependence of the model on some parameters is discussed.The results of the numerical simulation using historical data and experimental forecasting tests are also presented.
