Changes of air temperature and precipitation in Poland in the period 1951–2000 and their relationship to atmospheric circulation

An analysis of trends of mean monthly temperature and precipitation totals in Poland in the period 1951–2000 was carried out. Areal means of temperature and precipitation were used, averaged for 51 meteorological stations evenly distributed within Poland's borders. Sensitivity of air temperature and precipitation variations towards circulation was assessed. Circulation variations were expressed by sea‐level pressure in the 52.5°N, 20°E grid point and geostrophic wind calculated from meridional (45–60°N) and latitudinal (10–30°E) pressure gradients.
