Mori et al. identified two circulation patterns that drove winter temperatures in Eurasia from 1979 to 2013: the Arctic Oscillation (which confines colder air to the polar latitudes) and a pattern dubbed «Warm Arctic and Cold Eurasia» (WACE), which correlated both to sea - ice loss in the Barents - Kara Sea and to particularly cold winters; its impact has more than doubled the probability of severe winters in central Eurasia.

Meanwhile, dry regions in the subtropics will get even drier because of atmospheric circulation patterns that carry water vapor away to higher latitudes.
