【Abstract】 The weather satellite has more advantages on detecting fog dissipation than that of other general techniques, such as human observation from the surface. In this paper, the main theory of fog dissipation is set forth in short and the characters of fog dissipation are discussed. And some examples are introduced to illustrate these characters and rules from series of GMS\|5 satellite images. The results given in this paper includes that the dissipation rate of fog in a certain site is correlated closely with the thickness of fog there, the relative site in the fog area, weather conditions and other impacts of human. Though this study is preparatory and the conclusion is limited, these results will be helpful to the future research and supply references for monitoring fog dissipation by using images from GMS\|5 weather satellite.更多还原
