Additionally, the willows extract a lot of water from the ground so there's less surface recharge and
less snowmelt going into the ground.
Not exact matches
The glaciers are disappearing, and the annual
snowmelt is coming earlier each year, synchronizing it
less and
less well with the summer growing season.
Global warming leads to more intense droughts, hotter weather, earlier
snowmelt (hence
less humid late summers and early autumns), and more tree infestations (like the pine beetle).
Snowfall varies across the region, comprising
less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of
snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated
snowmelt extremely difficult.
In particular, more winter and spring flooding and drier summers are expected as well as
less winter snow (more rain) and earlier
snowmelt.
It might, however, decrease in spring since
snowmelt will be
less substantial.
