Abstract
Sea fog occurs frequently over the Yellow Sea in spring and summer which causes costly or even catastrophic events including property damage marine accidents public health and financial losses Case studies of advection and steam fogs using direct observation over the sea are constructed to better understand their formation evolution and dissipation A southerly wind supplies moisture to initiate advection fog events (AFs) Approximately -100 to -200W m(-2) of latent heat flux and -70W m(-2) of sensible heat flux during mature AFs are characterized with stable stratification which maintains dense fog by limiting downward mixing of dryer air Steam fogs (SFs) develop from flow of cold air over warmer water but are normally of limited persistence During the SFs a northerly wind decreases the air temperature below the sea surface temperature which increases the relative humidity through evaporation from the warmer ocean During mature SF 360W m(-2) of latent heat flux and 150W m(-2) of sensible heat flux are characterized with neutral and unstable atmospheric conditions The increase in wind speed and wind shear mixes dry air downward to the surface and limits the duration of the SF (C) 2010 Elsevier B V All rights reserved
