| Summary: | Abstract The research aimed at determining the variability of occurrence of frosty days in Poland and defining the impact of macro-scale circulation types on the occurrence of these days from December to March. The study used daily data on the minimum, maximum and mean daily air temperature for 15 stations located in Poland from 40 winter seasons between 1970/71 and 2009/10. During that period, a decrease in the number of frosty days was noticed across the greater part of Poland; still, these changes were not statistically significant. The conducted research study showed that, of macro-scale circulation types, the North Atlantic Oscillation and Scandinavian type had the most significant impacts on the number of frosty days in Poland. |
