Historical data

Investigating the temporal variability of snow cover extend in a given country, you may notice that sometimes one winter season significantly differs from another. Some seasons are severe, while other - not at all.

As 'severe' we can characterize a winter with a number of days featuring the snow cover, which covers most of the country. The winter season of 2005-2006 (plot below) in Poland was a one of the 'severe' type: snow covering almost the whole country was noted from mid-December to the end of March (nearly four months!).

On the other hand, the winter can be quite 'light', like in the season 2006-2007, with only few days with snow covering the whole territory of Poland.
