摘　　要：使用具有较高分辨率的NCEP格点数据对2008年7月8-11日和2010年2月22-25日发生在黄海海区的两次海雾过程的环流形势和特征参量进行了对比研究,以探讨黄海海区冬季雾与夏季雾产生机制的异同。结果表明,这两次海雾过程都是发生在稳定层结下的低压前部、高压后部型的平流冷却雾。海雾发生时表面行星边界层有抬升,海雾消散时表面行星边界层降低。冬季雾逆温层先减弱消失,然后海雾消散,与冬季雾相反,夏季雾是海雾先消散,然后逆温层消失,逆温层演变特征为该海域海雾的监测和定量预报提供参考。Using the NCEP grid data with higher resolution, the circulation situation and characteristic parameters of the two sea fog processes that occurred in the Yellow Sea from July 8 to 11, 2008 and February 22 to 25, 2010 were compared to explore the similarities and differences of the generation mechanism of winter fog and summer fog in the Yellow Sea area. The results showed that the two sea fog processes were advective cooling fogs of low-pressure front and high-pressure rear under stable stratification. When the sea fog occurred, the surface planetary boundary layer rose;when the sea fog dissipated, the surface planetary boundary layer decreased.In winter, the fog inversion layer weakened and disappeared first, and then the sea fog dissipated. In contrast to the winter fog, the summer fog dissipated first, and then the inversion layer disappeared. The evolution characteristics of inversion layer provide a reference for the monitoring and quantitative prediction of sea fog in this sea area.
