Abstract

Use was made of the longest-existing series of air temperature observations from Central Europe, specifically those for Warsaw, Kraków, Prague and Vienna. It was, above all, the course of mean annual values for air temperature that was analyzed, thus allowing this study to serve also as a basis for further, more precise studies including the variability and cyclicity of air temperature values in particular months. The application and attempted interpretation of periodograms drawn up on the basis of data for January, April, July and October has confirmed the above opinion. In general, considerable concurrence in the courses of mean air temperature values at the selected stations may be noted, and hence the influence of the same circulation mechanisms shaping air temperature over a large area during the two centuries.

Keywords: long air temperature series, mean annual air temperature, variability, periodicity
