摘要

摘要: 根据渤海冰情,在海冰动力学和热力学研究基础上,应用一种质点-网格海冰模式于渤海海域.该模式采用了质点-网格法,有效地避免了传统模式的数值扩散问题.该模式采用了冰厚分布函数,用多种类型冰代替用于渤海业务预报的平整冰、堆积冰和开阔水3-level模式.进行理想场的数值试验,模拟冰厚变化动力过程.还使用该模式和业务预报模式对于实际渤海冰情进行了不同个例的预报试验,发现该模式在提高冰外缘线预报精度方面有一定的优势.

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.
