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.
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.
