Dense fog burst reinforcement over Eastern China: A review

Throughout more than ten years of observations, strong dense fog (SDF) (visibility < 200 m) and extremely dense fog (EDF) (visibility < 50 m) often occurred in the central and eastern regions of China. This could lead to serious traffic accidents. This review summarizes the research results of dense fog in China, including the burst reinforcement features of strong dense fog (SDF) formation, the microphysical process of the fog body enhancement, the causes of burst reinforcement and the characteristics of the boundary layer structure. There are also remarks about fog dissipations. The research results show that there are still many important scientific problems to be solved about dense fog. These are briefly introduced at the end of this paper.
