Abstract

Abstract

By using the Fog Monitor (FM-100, DMT Inc. USA) droplet collector, the droplet size distribution and droplet number concentration of sea fog from 16 to 19 March 2008 were investigated in the Science Experiment Base for Marine Meteorology at Bohe, Guangdong Province. The microphysical structure and evolution of this sea fog event, especially the LWC (liquid water content) of sea fog, are analysed. According the observational data during the same period, the synoptic factors accounting for the low atmospheric visibility assocaited with this sea fog event were also analysed.It is shown that liquid water content of sea fog had a wave-variation during the sea fog development period.The main factor for the increasement of LWC was due to the increasement of larger droplets greater than 10 μm.Accompanied with the increasement of LWC, the droplet size distribution of sea fog became wider towards larger size, and the peak value kept increasing either. In the same range of LWC, different visibility samples exhibited various droplet size distributions. In the same large drolet number concentrations range, the main reason for lower atmospheric visibility was due to the increasement of the LWC. The low atmospheric visibility caused by sea fog were affected by many synoptic factors, such as wider homogeneous pressure field, weaker low-level wind speed, slightly unstable low-level atmosphere, higher humidity at the surface level and so on.
