DIURNAL AND ANNUAL VARIATION IN THE PROBABILITY OF VISIBILITY BELOW 10 KM,

Abstract

Horizontal visibility of the atmospheric layer near the ground is subject to daily and yearly fluctuations. The author utilized visibility data from geographic points with widely differing climatic conditions: Alma-Ata, Kiev, Batumi, Karadag, Tashkent, Sverdlovsk, Murmansk, Vladivostok, Petropavlovsk-Kamchatskiy, and Yuzhno-Kuril'sk. The fluctuations of visibility in all the locations were similar, the highest visibility being in the summer months. The relative humidity curves show the same trend. Daily visibility varied in a similar manner, the highest visibility being in the morning.
