ods). In the other seasons general increase of precipitation totals is expected. This
increase is more pronounced in the northern half of Central Europe and in the
mountains. Winter precipitation increase can exceed in the northern Slovakian
mountains also 30% compared to previous normal periods (1951–1990).

Snow cover depth and snow cover occurrence depend on air temperature and
precipitation regime even more significantly than in case of air humidity and evapotranspiration.
Mainly the regions with mean daily temperatures about 0°C during
the winter months are the most vulnerable. Such winter temperature regime concerns
the most of Slovak and Central European regions. It seems that the increase
in winter temperature by 1°C results in about 10% winter precipitation totals rise
and in 200 to 300 m snow line shift to higher elevation in the mountains. That is
why some decrease in snow cover days and sums of daily snow cover depths was
registered in altitudes below 800 m and some rise in altitudes above 1200 m in the
last two decades. It is supposed that such development will continue also in the
next decades, if increase in winter temperature and precipitation totals will remain.
