The “Warm‐Arctic/Cold‐continents” pattern during 1901–2010
The “Warm‐Arctic/Cold‐continents” (WACC) winter weather pattern is investigated using the European Centre for Medium‐Range Weather Forecasts 20th Century reanalysis data (ERA20C) spanning 1901–2010. Both the 1920–1940 and 1990–2010 periods are characterized by Arctic amplification (AA) and mid‐latit...
