Abstract

Abstract

Based on dynamic and thermodynamic research of sea ice and the ice conditions in the Bohai Sea,a particle-in-cell (PIC) sea ice model has been applied to the Bohai Sea,China.The PIC method is introduced into the sea ice model to efficiently reduce the numeric diffusion inherent in conventional models.The ice thickness distribution function is introduced in the model,as well,and the multi-category ice thickness distribution is used,instead of the three-level ice thickness distribution of level ice,rubble ice and open water in the Bohai Sea ice model Numeric experiments of the ideal ice fields are carried out for simulating the dynamic process of ice thickness variation.And comparison experiments of forecasts for different cases of the real ice conditions in the Bohai Sea are made by using the PIC model with the operational ice model.It is found that the PIC model has some advant age in improving ice edge forecast accuracy.
