Snow cover variability in Poland in relation to the macro‐ and mesoscale atmospheric circulation in the twentieth century
Abstract The main aim of the study is to investigate the atmospheric circulation impact on snow cover duration (SCD) and maximum seasonal depth of snow cover (MDS) in Poland in the twentieth century. The most important is to answer four questions: (1) which of the two, macro‐ or mesoscale atmospheri...
