| 1 | An Analysis and Modeling Study of a Sea Fog Event over the Yellow and Bohai Seas显示文摘In this study, a sea fog event which occurred on 27 March 2005 over the Yellow and Bohai Seas was investigated obser- vationally and numerically. Almost all available observational data were used, including satellite imagery of Geostationary Opera- tional Environmental Satellite (GOES)-9, three data sets from station observations at Dandong, Dalian and Qingdao, objectively reanalyzed data of final run analysis (FNL) issued by the National Center for Environmental Prediction (NCEP) and Regional At- mospheric Modeling System (RAMS) results. Synoptic conditions and fog characteristics were analyzed. The fog formed when warm, moist air was advected northwards over the cool water of the Yellow and Bohai Seas, and dissipated when a cold front brought northerly winds and cool, dry air. In order to better understand the fog formation mechanism, a high-resolution RAMS modeling with a 6 km×6 km grid, initialized and validated by FNL data, was designed. A 48 h modeling that started from 12 UTC 26 March 2005 reproduced the main characteristics of this sea fog event. The simulated lower visibility area agreed reasonably well with the sea fog region identified from the satellite imagery. Advection cooling effect seemed to play a significant role in the fog formation. | FU Gang GUO Jingtian Angeline Pendergrass LI Pengyuan | 2008 | Journal of Ocean University of China2008，7，1： | 26 |
