| Zusammenfassung |
| Changes in snow water equivalent (SWE) over Northern
Hemisphere (NH) landmasses are investigated for the early (2016–2035),
middle (2046–2065) and late (2080–2099) 21st century using a
multi-model ensemble from 20 global climate models from the Coupled Model
Intercomparison Project Phase 5 (CMIP5). The multi-model ensemble was found
to provide a realistic estimate of observed NH mean winter SWE compared to
the GlobSnow product. The multi-model ensemble projects significant
decreases in SWE over the 21st century for most regions of the NH for
representative concentration pathways (RCPs) 2.6, 4.5 and 8.5. This decrease
is particularly evident over the Tibetan Plateau and North America. The only
region with projected increases is eastern Siberia. Projected reductions in
mean annual SWE exhibit a latitudinal gradient with the largest relative
changes over lower latitudes. SWE is projected to undergo the largest
decreases in the spring period where it is most strongly negatively
correlated with air temperature. The reduction in snowfall amount from
warming is shown to be the main contributor to projected changes in SWE
during September to May over the NH. |
