摘要：

The aim of this article was to investigate the effect of macroscale circulation types on total cloud cover in Poznan-Lawica (western Poland) in years 1951 2015. The analysis was preceded by the characteristics of the long-term, annual, and seasonal changes in total cloud cover and cloud genera (data regarding observations of cloud genera covered the period of 1971-2015). The effect of six macroscale circulation types (Arctic oscillation. North Atlantic Oscillation, East Atlantic, East Atlantic/West Russian, Scandinavian, and Polar/Eurasian Types) on the total cloud cover was examined. The amount of cloud cover in Poznan was influenced by the macroscale circulation types, mainly in the warm part of the year. The North Atlantic Oscillation, Arctic Oscillation and Scandinavian types had the strongest impact there.
