MICROPHYSICAL CONDITIONS FOR THE FORMATION AND DISSIPATION OF FOG,

Abstract

Fog is defined as a phenomenon of water vapor condensation in the air layer next to the earth's surface (either over land or above water) at times when the daytime horizontal visibility is less than one kilometer. Observations on fogs at a number of stations in various regions of the USSR are made. Certain instruments for this purpose, for example, instruments for measuring the water content in fog, for measuring the visibility distance, for visually estimating its aggregate state, for measuring visibility distance in fog, and also installations for microphotography and cloud particles already are being used in experimental investigations.
