外文摘要：Fog is a common and hazardous weather phenomenon, so it is an urgent problem to predict the development of foggy weather accurately and timely in daily forecasting. In this paper, the ERA5 reanalysis data is used as the background field, and the initial field of the WRF mesoscale model forecast is combined with different physical parameterisation schemes to carry out numerical simulations for an individual case of foggy weather from 22 to 23 January 2021. ? The WRF model can better simulate the generation and extinction of fog. ? When the relative humidity is greater than 80%, the wind is low, the atmospheric structure is more stable and the subtropical high pressure moves northward, it is easy to produce foggy weather. ? This fog is due to the transport of warm and humid air from the sea surface to the coastal area of a certain place by air currents, which meets the cold air mass of the mainland at the coastal junction. ? 2022 SPIE.
