Dynamic modeling is being conducted to predict the formation and dissipation processes in marine fog situations. The physical processes of condensation, evaporation, precipitation, radiation, and turbulence are being established by using available laboratory experiments for the purpose of analyzing the transport phenomena of heat, mass, and momentum in an atmospheric-oceanic system. The verification of analytical results with field data obtained in actual fog situations establishes the strengths and weaknesses of our current program. Topics that still need to be investigated in the laboratory include evaporation at the ocean surface affected by turbulence, and evaporation and condensation of airborne fog particles affected by radiation and turbulence. Open ocean fog situations can be analyzed by employing the boundary layer theory, which uses the existing turbulence data for the closure of the governing mathematical equations. Harbor and shoreline fog situations can be examined by using the separated flow theory, which requires more detailed turbulence data for establishing a realistic closure scheme.
