摘　　要：对数值模拟的研究现状进行了总结梳理,分析了已有研究的不足,并根据研究目标在已有研究结论基础上有针对性地设计了敏感性实验方案。经过与实地观测的结果对比来看,与海雾模拟密切相关的边界层参数化方案中的YSU方案对我国黄渤海海区的不同强度海雾均具有良好的适用性,而长波辐射方案中的Fu-Liou-Gu方案则具有更好的普适性,在这种核心方案配置下的模拟结果均可满足一般科学研究与预报业务的需求。In order to study the optimal parameterization scheme of WRF V3.9 in simulating sea fog in the Yellow Sea and Bohai Sea, this paper summarizes the current status of research on numerical simulation and its shortcomings, and designs sensitive tests according to the research objectives based on the present conclusions. By comparing with field observations, we find that the boundary layer parameterization scheme YSU shows good applicability in the Yellow Sea and Bohai Sea with different sea fog intensity., and long-wave radiation scheme Fu-Liou-Gu shows better universality. The simulation results using those core scheme configurations can meet the needs of general scientific research and forecasting services.
