Simulation and Test of Sea Fog Numerical Prediction System for Yellow Sea and Bohai Sea

Huang Bin Chen Tao Chen Jiong Deng Liantang(National Meteorological Center,Beijing 100081)  
Based on the PSU/NCAR mesoscale model version WRF 2.2,the Sea-Fog Numerical Prediction System for the Yellow Sea and Bohai Sea is constructed by choosing optimally optional microphysical processes and boundary layer schemes,with the sea fog diagnostic equation coupled into the WRF model.Continuous operational sea-fog prediction experiments and verifications are made from 30 June to 1 August of 2007.Several testing schemes are devised according to the characteristics of the data from coastal conventional stations and satellite monitoring data.The results show that the numerical prediction system is able to predict sea fog with a satisfactory precision,especially heavy fog,which can provide helpful guidance for operational heavy fog prediction.The testing schemes are useful attempts for solving the problems for the scarcity of meteorological data on the sea areas,which is helpful to the quality control and application of numerical predictions.
