CORRELATION OF ANNUAL AVERAGE SEASONAL VALUES OF TEMPERATURE WITHIN THE ATMOSPHERIC BOUNDARY LAYER AND AMOUNT OF STRATIFORM LOW CLOUDS

摘要

The work presents the results of the evaluation of the correlation degree of annual average seasonal temperature within the atmospheric boundary layer (at heights of 0, 400, 800, 1600 m) and the amount of low stratiform clouds (Sc, St, Ns) for the period from 1969 to 2013 performed according to the data from 6 typical weather stations of the Siberian region (Dickson, Tiksi, Salekhard, Omsk, Yakutsk, Chita). It is shown that the significant correlation (positive in winter, spring, autumn and negative in summer) between annual average seasonal values of the amount of low stratiform clouds and the temperature of the atmospheric boundary layer prevailed in Siberia during the study period. And the values of correlation coefficients (in absolute value) are more than 0.75 almost everywhere, and ones reach a maximum (0.84-0.88) at the altitude of 400 m.
