Events of very high concentrations of 7 Be cosmogenic radionuclide have been recorded at low-elevation surface stations in the subpolar regions of Europe during the cold season. With an aim to investigate the mechanisms responsible for those peak 7 Be events, and in particular to verify if they are...
