Abstract
This paper reviews recent researches in the Meteorological Office designed to elucidate how the physical processes involved in the development of radiation fog interact to deter mine its formation, growth and dissipation. The results of field measurements and computer models are combined to illustrate the delicate balance that exists between radiative cooling of the air and droplets, conduction of heat from the soil, turbulent transport of heat and moisture within the fog and the deposition of droplets and dew on the ground. The clearance of fog by solar radiation and by the advection of a low-level cloud sheet is also investigated.
