Abstract:

The aim of this study is assessment of thermal comfort conditions during heat waves in Ukraine in the years 1961-2015. The assessment is based on the thermal index Physiologically Equivalent Temperature. This study uses data from 29 meteorological stations across Ukraine. The research showed an increasing frequency of occurrence of heat waves (HWs) in the territory of Ukraine in the last decades. East and south Ukraine (except of coastal stations) experienced the most strenuous human-biometeorological conditions whilst HWs were recorded in the country. Lower mean PET values were found in Western region of the country. The obtained results suggest that the HW event of 2010 was the longest and the most strenuous HW in human-biometeorological terms since 1961.

Keywords: heat waves, human thermal comfort conditions, heat stress, physiologically equivalent temperature, Ukraine

Abstract:

The human-biometeorological conditions in Kyiv (Ukraine) and changes in the frequency of heat stress during the summer period due to recent climate trends were analyzed. The evaluation based on physiologically equivalent temperature (PET). The results revealed the highest probability of thermal comfortable conditions in Kyiv is from the last 10-day period of April to the end of June and from the last 10-day period of August to the end of September. The probability of heat stress reached nearly 90% during the second and third 10-day periods of July. A pronounced increase in thermal stress during the studied heat wave cases (HW), as well as increasing amount of days with heat stress in the period 1991-2015, were found.
