Melting snow

Melting snow in the valley of the Breitenbach near Böhlen in Thuringia

As snowmelt is called the thawing of snow to water when the ambient temperature, mostly due to the change of the season, increases. Snowmelt can also occur in winter when mild air is sucked in from the southwest at the front of a low pressure area . A special case is the snowmelt under the influence of the foehn , when the air is heated adiabatically dry after crossing a mountain . Since the relatively dry air can absorb a lot of moisture, the effect of the snowmelt is particularly great. Melting snow usually causes increased water levels in streams, rivers and lakes, and not infrequently leads to floods.
