Winter-responding proxy temperature reconstructions and the North Atlantic Oscillation
Instrumental temperature data for the Northern Hemisphere (30°–90°N) clearly indicate that winter season variability is larger than equivalent measures for summer. This should not be surprising as temperatures in winter are dominated by variability caused by changes in atmospheric circulation featur...

Instrumental temperature data for the Northern Hemisphere (30°–90°N) clearly indicate that winter season variability is larger than equivalent measures for summer.

Here we consider most of the few winter-responding annually resolved proxy reconstructions of temperature from the northern North Atlantic and northwestern European regions.
