| 摘 要： | 在海冰动力学和热力学的研究基础上,开发应用于渤海的质点-网格海冰模式.该模式采用质点-网格法,有效地避免了传统海冰模式的数值扩散问题.该模式采用冰厚分布函数取代传统渤海业务海冰预报模式中平整冰、堆积冰和开阔水的三类海冰分型.应用质点-网格海冰模式对2003年～2004年冬季渤海冰情进行了业务化逐日数值预报试验,并对预报结果进行统计检验和分析比较.

| Abstract: | Based on dynamic and thermodynamic research of sea ice, a Particle-In-Cell (PIC) sea ice model has been applied to sea ice forecasting in the Bohai Sea. The PIC method is introduced 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. Numerical sea ice forecasts of the whole 2003/2004 winter for the Bohai Sea were made by using the PIC model and the operational ice model separately, and the statistical analysis and comparison of sea ice forecast results were made. |
