Abstrakt
The paper presents the variation and values characterising atmospheric precipitation and air temperature by hydrological years, as well as their changes during the growing season. Recent years saw meteorological conditions that can have an unfavourable impact on water resources of the Białowieża Primeval Forest and on the state and stability of forest hydrogenic habitats: long-term droughts during the growing seasons of 1997 and 2000, decreasing number of days with the highest precipitation, i.e. exceeding 20.0 mm; gradual increase in the mean annual temperature caused by wormer winter half-years; decrease in the number of days with the lowest temperatures and concurrent increase in the days with the highest temperatures. The conditions occurring in the Białowieża Primeval Forest were also related to Poland’s climatic classification based on the presence of days with a given weather type worked out by Alojzy Woś.
