Abstract
The paper summarizes the mean daily air temperature in Lublin (data from the Meteorological Station UMCS) in two 30-year periods: 1951–1980 and 1981–2010. The range of variability and frequency of air temperature values was analyzed in 2- and 5-degree intervals. The mean air temperature in the years 1981–2010 was 8.7°C and it was higher than the mean air temperature for years 1951–1980 for 0.8°C. In the annual course during 10 months mean average monthly values were higher in the second period. The biggest differences concerned the months from January to March. The comparison of results obtained from two 30-year periods showed that the variability range of the mean daily air temperature has not changed (from -25.9 – -24.0°C to 28.1–30.0°C). however, the number of days with temperature ˃ 20°C has significantly increased, on average by 6 days during the year, while the number of days with daily average temperature ≤ -10.0°C has decreased on average by 3 days in a year. In the annual course the highest changes in two analyzed periods are observed in January. In this month in the years 1981–2010 there was increase in the number of days with daily air temperature above 0.0°C by 4 days.
