Abstract

Synoptic conditions of heavy snowfalls at 4 stations in Europe (Oslo, Bremen, Smolensk and Budapest) were analyzed using daily data of snow cover depth from 50 winter seasons (1960/1961-2009/2010). Composite maps of the sea level pressure and 500 hPa geopotential height means and anomalies were presented for the days with an increase in snow depth by >10 cm, for each station separately. Additionally, 48 h back trajectories of air masses for the chosen days with the highest amount of snowfall were constructed, using the NOAA HYSPLIT model. Negative anomalies of sea level pressure and 500 hPa heights, which correspond to low-pressure systems spreading over Europe, are prerequisites for the occurrence of heavy snowfalls at each analyzed location. It is showed that there are 2 main sources of air masses bringing abundant snowfalls in Europe : the Atlantic region and Mediterranean
