Abstract:

Based on data of eight-time daily meteorological observations (during 1981-1985) in one of Siberian cities (Kemerovo) and at several points, at the distances of several tens kilometers from Kemerovo, the study has been performed of the effects of the anthropogenic factor on the fields of air temperature and humidity, as well as on the formation of fogs in the city. The close correlation between temperature variations and water vapor pressure (the correlation coefficients are, as a rule, no less than 0.60-0.70) and the weak correlation (the correlation coefficients from 0.05 to 0.10) between the temperature and the pollutant concentration (such as СО, NO₂, ammonia, dust) enable us to assume that the change of content of anthropogenic water vapor and the greenhouse effect caused by it are of crucial importance in the formation of heat island in the city. Higher temperatures favor the decrease of the fog occurrence in the city as compared with its environs.
