Abstract

The 2012-2013 winter was unusual in the Carpathian region from several aspects. Especially the precipitation anomaly was very high. Our motivations are (i) to evaluate the series of synoptic patterns in late winter and early spring leading to these extremes, and (ii) to provide possible explanation of the physical processes behind them. The main characteristics of the dominant patterns are as follows: the jet-stream is nearly stationary above the Mediterranean region and Mediterranean cyclones formed frequently along the jet. According to the literature there is a link between the North Atlantic Oscillation (NAO), the Arctic Oscillation (AO), and the position and intensity of the jet-stream and these are also linked to the local weather conditions. First, we calculate correlation patterns between daily data of several elements near the surface and at different isobaric levels, and daily NAO and AO index values for 30 years (1981- 2010). Then, similar analysis is carried out for all the seasons and months.
