Abstract
\n<\/strong>The results of the latest WMO and NOAA reports on climate show that 2019 was one of the warmest years in the history of meteorological measurements. Therefore, the aim of the paper was to evaluate thermal conditions in 2019 in the selected regions of the Lower Silesia, Poland, and compare the results to the multiannual period of 1971-2019. Additionally, analysis on bio-thermal conditions were carried out in order to examine how changes in thermal conditions affects biometeorological issues. The analysis was carried out on the basis of meteorological data for 1971-2019 from IMGW-PIB stations representing various altitude. Wroc\u0142aw (120 m a.s.l.) represented the lowlands, K\u0142odzko (356 m a.s.l.) the lower mountain parts, while \u015anie\u017cka (1603 m a.s.l.) represented the summit zone of the Giant Mts. In case of bio-thermal conditions evaluation, subjective temperature index STI, developed on the basis of MENEX model, was used. The results showed that 2019 at the considered stations was characterized as the warmest (Wroc\u0142aw, K\u0142odzko) or one of the warmest years (\u015anie\u017cka) in the 1971-2019 period. Furthermore, for 1971-2019, increasing and statistically important trend was noticed for mean annual air temperature and the number of heat and warm days. The rate of increase in mean air temperature was equal to 0,5^{o<\/sup>C\/decade in Wroc\u0142aw, 0,3^{o<\/sup>C\/decade in K\u0142odzko and 0,4^{o<\/sup>C\/decade on \u015anie\u017cka. On the other hand, decreasing tendency was observed for annual frequency of frosty and icy days. In terms of bio-thermal conditions, \u2018cool\u2019 thermal senses were prevailing throughout the year in the lower located regions. During the summer season, higher frequency of heat stress was noticed for both 2019 and 1971-2019. In case of \u015anie\u017cka, intensive cold stress (\u2018extremely cold\u2019, \u2018very cold\u2019 and \u2018cold\u2019) dominates during the cold season. In the warm season, \u2018cool\u2019, \u2018comfortable\u2019 and \u2018warm\u2019 conditions are also observed with no weather types considered as heat stress. Comparing bio-thermal conditions in 2019 to 1971-2019, lower frequency of cold stress occurred in 2019 at each station. In the lower located regions, higher number of days with heat stress and \u2018comfortable\u2019 conditions was noticed. On \u015anie\u017cka, frequency of \u2018cool\u2019, \u2018comfortable\u2019 and \u2018warm\u2019 conditions increased if compared to 1971-2019. Therefore, in case of further increase in air temperature and frequency of heat and warm days, additional increase in heat stress frequency can be expected in the lower located regions. On the other hand, improvement in bio-thermal conditions can be noticed in the summit zone of the mountains because of increase in thermoneutral conditions frequency. Nevertheless, it should be emphasized that in spite of increase in air temperature, \u2018very cold\u2019 \u2018cold\u2019 and \u2018cool\u2019 thermal senses should still be predominant throughout the year in the summit zone. As bio-thermal indices are often considered in evaluations of weather conditions for tourism, the results of the analysis can be used for assessment of recreational potential of the Lower Silesia.
