abstract:
This paper characterizes average decade air temperature values and changes in temperature over subsequent decades. Temperature data for 1951-2000 were obtained from the Agrometeorological Observatory in Felin near Lublin. The average decade air temperature fluctuated from –3.7oC (first and second decade of January) to 18.5oC (first decade of August), that is by 22.2oC. The changes in temperature over subsequent decades were classified in intervals of the width of 2,0oC. Interval of minus 2,0oC to 0,0oC was the most populated, with the interval of 0.1 oC to 2,0oC in the second place. An increase of temperature was most prevalent in the two subsequent decades, March 3rd (86% in the sample with 50 repetitions), then April 1st (82%), and another maximum was recorded on June 1st (80%). Increases of temperature occurred the least frequently (20% of repetitions) in the second and third decades of September and in the third decade of October. The longest periods of increases of temperature covered nine subsequent decades, the longest periods of decreases of temperature covered eight subsequent decades.
