基于中尺度数值大气模式的海雾特征参数研究

In order to study the echo characteristics of sea-skimming laser weapons in the sea fog aerosol environment, it is necessary to further obtain the parameters of sea fog aerosols. Based on the mesoscale numerical atmospheric model WRF, a more intensive η layering was set in the vertical space for the spatial region where the sea fog exists, and the formation process of sea fog was numerically simulated from April 28 to April 29, 2015. The data of the sea fog characteristic parameters, such as the cloud-water mixing ratio and the fog top height, are calculated, and the horizontal visibility data affecting the laser echo is calculated. The results show that the η layer number can be further refined according to the spatial region where the sea fog exists (up to 400 m above sea level), and the characteristic parameters of sea fog can be further refined to improve the accuracy of the acquired data. The visibility parameter can be calculated from the sea fog characteristic parameters, such as cloud-water mixing ratio. The calculating accuracy is affected by the accuracy of the sea fog parameters.
