Abstract From 26 January 2019 to 27 February 2019,the Meteorological Observation Centre of CMA conducted a sea fog observation experiment in Hengsha island,Chongming district of Shanghai.This paper analyzes the microphysical form of sea fog,the observation principle and actual observation effect of lidar and millimeter wave radar equipment.At the same time,the problems of the mutual verification of ground visibility meter and raindrop spectrum data,and the assumption of effective detection distance etc are compared and analyzed.The results show that the two types of equipment can describe the physical structure and characteristics of fog from different angles in the detection of sea fog observation,and jointly promote the observation ability of sea fog.
