Abstract

The problem of quantitative estimation of cyclone influence on changes of regional climate characteristics was considered using results of instrumental monitoring data processing. The role of different origin cyclones in meteorological fields transformation, reorganization of weather formation processes, contribution to mean meteorological values, and composition of phases of the annual rhythm has been investigated. To make quantitative estimation of a cyclone influence on the regional climate characteristics, we use increment of daily mean temperature, change of integral estimation characteristics during cyclone action time, and variation of seasonal average meteorological variables at the area of the cyclone action. Techniques for multilevel analysis of climatic monitoring data and methods for calculation and comparative estimation of seasonal variations of meteorological variables have been developed for seasons with high and low cyclone activity. Evaluations of contribution of different type cyclones to changes of monthly and seasonal temperatures, and season's duration have been made. The climatic estimation of influence of cyclone activity on changes of January temperature has been performed using empiric functions of daily temperatures distribution.
