The effects of global warming in the Arctic are intensified, with rapidly rising temperatures and significant loss of sea ice. Changes in temperature and precipitation variability and extremes in the Arctic are regionally and seasonally dependent, strongly linked to sea-ice loss. Large-scale weather systems play a key role in shaping seasonal temperature and precipitation extremes in the Arctic, which persists under climate warming.
The effects of global warming are strongly amplified in the Arctic, causing rapidly rising temperatures and ongoing dramatic loss of sea ice, which itself is subject to large interannual variability. We investigate changes in seasonal-mean temperature and precipitation, its variability and extremes, using large-ensemble climate model data with a representative concentration pathway 8.5 forcing scenario for historical (S2000) and end-of-century projections (S2100). Our results reveal regionally and seasonally dependent changes in Arctic interannual temperature and precipitation variability that are strongly linked to sea-ice loss. We show a doubling in precipitation variability over the Arctic Ocean and a significant reduction in temperature variability in the Barents Sea. Extremely warm seasons in S2000 rank among the coldest seasons or become unrealistic in S2100. We further show the key role of large-scale weather systems for shaping seasonal temperature and precipitation extremes in the Arctic which persists under climate warming.
