Opis:
Analysis of time series was performed of cloudiness, air temperature and precipitation for the years 1951-2000, the data used representing lowland Poland. The properties of the temporal course of these elements of climate and the interrelations between their variability in time have been determined. The strength of dependence of precipitation and temperature upon the magnitude of cloudiness in the annual cycle has been assessed with the linear correlation coefficient. The essential climate-forming role of cloudiness has been confirmed. The magnitude of cloudiness over Poland explains up to 70% of variability of temperature and precipitation. These interrelations are the strongest in the warmer half of the year. Atmospheric circulation and cloudiness explain up to 85% of variability of the climate elements studied.

Opis:
There are many classifications of atmospheric circulation types. In Poland, the most important one, used by Polish weather services, is the classification of circulation types developed by Lityński. This paper proposes four modifications to the currently used algorithm for determining atmospheric circulation types. The proposed algorithms have been compared and it has been shown which one produces a catalogue of circulation types in which the division of the distribution of the values of the three indices (the zonal index Ws, meridional index Wp and cyclonicity index Cp) into three classes is the closest to being equally likely. In 19862015, the classification scheme that deemed to be the best, difered in above 19% of cases from the currently used classification.

Opis:
In the paper the influence of atmospheric circulation on selected dangerous weather phenomena in Europę in the year 2000 has been presented. Dangerous weather phenomena include: 30 days with thunderstorms in Poland and 26 examples of such phenomena in Europę (tornados, strong winds, thunderstorms, torrential rains, floods, etc.). The NAO index (North Atlantic Oscillation) served to determine the character of the circulation that influenced the occurrence of catastrophic phenomena in Western, Central and Southern Europę. The J. Lityński classification of circulation types was used to thunderstorms occurring in Poland only. Most catastrophic phenomena during the positive NAO phase (predominance of zonal circulation) happened in Western and Central Europę. During the negative NAO phase (predominance of meridional circulation) the regions of the Mediterranean Basin were more freąuently affected. In the case of thunderstorms in Poland in the year under investigation (2000) their occurrence was related to the inflow of air masses from the northern sector.
