摘要
Abstract
In this paper, we have investigated a dense fog event occurred around the coastal region of the Jia-odong peninsula during the summer of 2009. The detailed synoptic situation are examined and physical mechanism are discussed. As shown in the result, the sea fog occurrence depends on air temperature and sea surface temperature (SST). The frequency of sea fog increases greatly when the air-sea temperature difference is in the range of 2-4°C; and the sea surface relative humidity is more than 90%; and the lower layer prevailing wind force is in 3-4 grade. The sea fog event is simulated by WRF model and the area of lower horizontal visibility is calculated based upon the model outputs. The modeled sea fog region agree well with the observational data, indicating that the model can reproduce the evolutionary process of a real sea fog event well. The model presented is capable of simulating the three-dimensional structure of sea fog.关键词
