Abstract
A set of unfavorable climatic factors determines how extreme the environment is for humans in particular regions. The Arctic and Antarctic (polar) regions are generally considered to be the most extreme environments. Assessing the extreme conditions is of importance for developing life support systems and personal protective equipment, implementing proper labor management, and preventing frostbite. Several methods are currently used to assess the climate severity, but none of them addresses the level of discomfort for humans. Two indices, the Wind Chill Index (WCI) and Bioclimatic Index of Severity of Climatic Regime (BISCR), were previously developed to estimate the level of bioclimatic discomfort. With the indices, bioclimatic parameters were evaluated for eight Antarctic stations: Amundsen–Scott, Bellingshausen, Byrd, McMurdo, Mirny, Molodezhnaya, Novolazarevskaya, and Vostok. Monthly and annual data on air temperature, wind speed, relative humidity, altitude, and air pressure were used to calculate the WCI and BISCR. The BISCR, which includes hypoxia as a component of bioclimatic discomfort, was found to better predict the impact of meteorological conditions on the human body in Antarctica and to allow comparisons of outdoor climatic conditions and indoor microclimate for Antarctic stations. The WCI proved to detect no difference between stations from different climatic zones, especially in indoor conditions, thus being unsuitable for comparisons. The findings can be used for labor management at inland Antarctic stations to minimize possible health risks.
