Abstract

The work presents the results of the statistical analysis of the characteristics of the low stratiform clouds, obtained according to the 8-term meteorological observations of 60 Siberian weather stations for the last 45 years (from 1969 to 2013). Researches of the amount and the base height of low stratiform clouds (Sc, St, Ns) have been conducted for four seasons. Wherein the statistics such as the average value (cloud amounts (balls)) and the frequency (%) for five gradations: 0, 1-3, 4-6, 7-9, 10 cloud amounts were used in the analysis of the amount of low-level stratiform clouds and the averages (km) and repeatability (%) for six gradations of the base height: 0.05-0.2; 0.2-0.4; 0.4-0.8; 0.8-1.2; 1.2-1.6; 1.6-2.0 km, complemented by the gradation "cloudiness" (0) were used in the analysis of the cloud base height.
