The East China Sea accommodates intense shipping activity but the ocean transport is frequently influenced by fog events in late winter and spring. Few studies have addressed the modeling capability of fog simulation over this area. In this study, fog events in past few years were simulated using different two-moment cloud microphysical schemes in the Weather Research and Forecast model (WRF) to understand the model performance of sea fog simulation. The results are evaluated by visibility observation from the coastal meteorological stations and effective radius and cloud optical depth from satellites. The presentation will also address the effects of aerosol-cloud interactions and air-sea interactions.
