Abstract : Measurements of the microphysical and micrometeorological characteristics of two fogs occurring at sea 30 nmi off the coast of California were obtained. The fogs exhibited formation features, vertical temperature structure and microphysical characteristics similar to those observed on shore in California coastal fog. One of the fogs formed over cold water, while the other formed over relatively warm water; in each instance, marked visibility improvements were observed at the surface downwind of abrupt gradients in surface water temperature. The observations also show that fog occurrence at the surface at distances exceeding 30 nmi off shore is definitely a diurnal effect and indicate that radiational cooling at the top of the fog is much more important than has been previously considered.
