“…Other studies show that Miami [Huang et al, 2020] had a very high frequency of moderate and strong unacceptable heat stress (54.7 %), while in Gothenburg the overall hours of «no thermal stress» increased [Thorsson et al, 2011]. Heat load index in Serbia defined stressful thermal conditions in July 2011 on six different weather stations [Pecelj, 2012;Pecelj et al, 2013]. Increased values were also fixed in 2000 and 2007 in Loznica, Belgrade, Novi Sad [Мilovаnоvić et al, 2017].…”

The ecological state of the environment, climatic conditions with pronounced seasonality, variability, anomaly summer heat and regional manifestations of climate change, have a certain negative impact onwell-being, health and comfort of life of the population. To assess climatic comfort of a person, a bioclimatic index (equivalent-effective temperature) was used, which allows to evaluate thermal sensation of a person under a certain combination of meteorological parameters. In this study we used daily observation data (surface temperature, air humidity and wind velocity) at 34 meteorological stations in Ukraine for the period 1990—2020. Analysis and ranging of data, which characterize the thermal bioclimatic conditions, were done. It was found that the weather conditions with apparent temperature of very cold—cold—cool—slightly cool compose about 268 ± 9 (73 %) days per year. Thus, the population of Ukraine experience conditions of physiologically cold stress during the prevalent time of the year. Weather conditions that fall into gradations very cold –(30 ... 23) and cold –(23 ... 12) represent 6 ± 5 (~2 %) and 42 ± 17 (~12 %) days per year respectively. They can consequently cause extreme cold and strong cold stress and have a tendency towards decreasing repeatability. The largest number of days on average across the country have such gradations as slightly cool 0 ... 12 and cool –(12 ... 0), 113 ± 10 (31 %) and 107 ± 8 (29 %) days per year respectively. Slightly cool weather conditions are typical for the warm period of the year, mainly autumn and spring, and partially winter, while cool –(12 ... 0) is more prevalent in winter, autumn and spring seasons. Comfortable and subcomfortable thermal conditions for human with apparent temperature of slightly warm and warm compose on average 96 ± 8 (~26 %) days per year. Comfortable thermal conditions for human on the territory of Ukraine represent about 47 ± 13 (13 %) days per year and are typical for the warm period from April to October, with maximal values in summer: June 10 ± 3, July 17 ± 4 and August 15 ± 4 days per month. A number of days with subcomfortable thermal conditions for human on the territory of Ukraine compose also 48 ± 3 (13 %) days per year. Moreover, for May—September it has almost an equal number of days per month from 7 to 12 with minimal values in April, October and November, about 1—2 days. There is a tendency to increase in the number of days with comfortable thermal conditions for human in summer by 0.2—0.3 days per month for the period 1991—2020. The trend is 0.83 days per year (on average 25—30 days were added each year) for the period 1991—2020. Thus, comfortable climatic conditions for the local population in Ukraine increase during the warm season. However, the frequency of hot apparent temperatures (23 ... 30) has increased, especially during summer period, which can subsequently cause strong and extreme heat stress for humans. In particular years, it was recorded up to 5—19 days per year. For that reason, the climatic conditions of Ukraine have a certain potentially comfortable climatic resource(in June—August): Western region has a minimal climatic resource (23—40 %); Northern region has a sufficient climatic resource (36—53 %); Central region has an optimal climatic resource (40—60 %); Southern region has an optimal climatic resource (40—67 %).

“…Предмет овог рада је анализа еквивалентних температура на територији града Крагујевца, док је циљ рада сагледавање утицаја наведеног биоклиматског индекса у функцији туризма и рекреације.

“…The subject of this paper is the analysis of equivalent temperatures in the territory of the city of Kragujevac, while the aim of this paper is to examine the impact of the mentioned bioclimatic index on tourism and recreation. There are many authors who are considering one or more bioclimatic indices on the example of larger area entities (Vujević, 1961;Malinović-Miličević, 2013;Basarin et al, 2014;Pecelj et al, 2017;Basarin et al , 2017), urban zones (Matzarakis & Endler, 2010;Matzarakis & Nastos, 2011;Pecelj, 2013;Pecelj et al, 2013) as well as spa locations Majejka, 2003;Stojićević et al, 2016) .…”

A more complete climate image of a site is obtained by analyzing bioclimatic indicators. In this paper, an analysis of the physiological sense of heat in the territory of the city of Kragujevac was presented. Bioclimatic considerations are based on the equivalent temperature, which represents the combined influence of air temperature and water vapor pressure. Based on these two climatic elements, the corresponding equations and the Krüger anthropo-climatic classifications, three climate types and nine physiological sensations of heat for the territory of the city of Kragujevac were isolated. Their significance in bioclimatology is that they cause different sensations of heat in healthy and sick people, and can serve as the basis for the expected types of bioclimate during the year. Urban areas are areas of higher population concentration to which the climate elements act stimulating or, on the contrary, discouraging, which depends on the person's health. For the needs of this work, a thirty-year climate period (1981-2010) was analyzed based on the data obtained from the weather station Kragujevac. There are significant historical and tourist sites and natural resources in the city and its surroundings, which can be valorized complementarily. Analyzed values of equivalent temperatures can be used for the planning of tourist activities and in means of tourist propaganda. For this purpose, this work can be a solid bioclimatic basis.

“…To calculate this, a combination of three main heat fluxes is used: total thermal accumulation (S), absorbed solar radiation (R), and heat loss through evaporation (E). The UTCI is based on the Fiala multi-node model [6,9,10], and includes the capability to predict wholebody thermal effects, such as hypothermia and hyperthermia, heat and cold discomfort, and local effects, i.e. the cooling of the face, hands and feet, and frostbite.…”

This paper presents part of the research in the field of human bioclimatology and refers to biothermal conditions in different geographical environments in Serbia: an urban area and a mountain of medium height. The goal of the paper was to show bioclimatic differences during the summer between the city of Belgrade (116 m a.s.l.) and the mountain resort of Zlatibor (1498 m a.s.l.). The basic principle of bioclimatic analysis is the human heat balance between man and environment. This methodological approach is a combination of physiological and meteorological parameters that result in thermophysiological bioclimatic indices: heat load (HL) in man and the Universal Thermal Climate Index (UTCI). For this analysis, weather data for July, as the warmest month, was obtained, using daily meteorological data for the decade from 2000 to 2010. Results for July indicate a considerable difference between the two abovementioned environments. HL in Belgrade was dominated by degrees of comfort "hot" and "extremely hot, with the highest value of 4.540, while for Zlatibor the dominant degree of comfort was "warm". The UTCI in Belgrade has dominated by strong heat stress and moderate heat stress, compared to Zlatibor where the UTCI is dominated by moderate heat stress. In addition, a significant part of the monitored decade on Mt. Zlatibor was without heat stress, with the exception of 2006 and 2007, indicating favorable biothermal characteristics. Therefore, compared to Belgrade, with its considerably lower overall heat stress Zlatibor has the characteristics of a site with favorable bioclimatic qualities.
