PARTICULAR FEATURES IN CHANGES OF CLIMATE COMFORT FOR HUMAN IN BELARUS FOR MONTHS AND SEASONS OF THE YEAR

Abstract

In this article the study of comfort level of climate has been performed on the basis of analysis of spatiotemporal changes of bioclimatic indexes: effective temperature, equivalent-effective temperature and bioclimatic air heat content index for the period from 1966 to 2020. The increase in average temperatures, the decrease in wind speed and insignificant changes in air humidity led to the improvement in the comfort level of climate and weather and decrease in frequency of days with very cold weather. Usually, the increase in climate comfort level was less evident in mid-seasons than in winter and summer. In total, since late 1970s the most significant increase in values of climate comfort indices was observed in July–August and November–December; significant increase in values of effective temperature and equivalenteffective temperatures was also observed in February–April. This pattern of changes corresponds to climate changes during distinct phases of warming period, characterized by more significant increase in the average temperature in certain
 seasons. Thus, due to the spatiotemporal heterogeneity of climate warming, the nature of changes, bioclimatic comfort
 indices is also heterogeneous. Nevertheless, it is possible to state that values of comfort indexes steadily increase since 1980s.
