Abstract:

The data of diurnal observations on the territory of Western Europe and Soviet Union in 1963 and 1964 and surface synoptic maps (00:00 and 12:00 GMT) are used to study the conditions of formation of fogs and meteorological hazes in different meteorological situations. In contrast to the widespread opinion, fogs and even hazes are more often formed in cyclones than in anticyclones. Data on the frequency of occurrence of fogs and hazes as a function of air pressure, type of the pressure system, and distance to the center of synoptic vortex make it possible to conclude that the main role in fog and haze formation belongs to the dynamic factors: advective and turbulent flows of heat and water vapor, as well as to heat influx from the soil.
