In Lesko and Lublin, Poland, from 1981 to 2005, the UTCI values were calculated for 8 observation terms a day. Thefrequency of the UTCI classes determined as ‘cold stress’ was dominant in Lesko and in Lublin (65-66%). The frequency ofclasses determined as ‘heat stress’ was observed in 3% of all situations. On the other hand, restricted to the 12 UTC Julyand August term, the frequency of heat stress classes exceeded 40% in Lublin. Correlation between the UTCI in Lesko andLublin (Poland) was stronger in spring and autumn than in summer and winter. Correlation between the UTCI and themeridional circulation index was more significant than between the UTCI and zonal circulation index in the period fromApril to November in both stations. The opposite situation occurred in February.
Keywords: UTCI, cold stress, heat stress, atmospheric circulation, zonal circulation index, meridional circulation index
