Variability in seasonal forecast skill of Northern Hemisphere winters over the 20th century

Variability in seasonal forecast skill of Northern Hemisphere winters over the 20th century

Seasonal hindcast experiments, using prescribed SSTs, are analysed for Northern Hemisphere winters from 1900-2010. Ensemble mean Pacific/North American index (PNA) skill varies dramatically, dropping towards zero during the mid-twentieth century, with similar variability in North Atlantic Oscillatio...
