Two major modes of Northern Hemisphere circulation in early winter. a EOF-2 and b EOF-3 of early winter sea level pressure (SLP) and c, d corresponding principal components (PCs) for 1958–2015, respectively. Thick black lines in c, d indicate 11-year running means. Regressed anomalies of 300-hPa geopotential height onto PCs of e EOF-2 and f EOF-3, and g ENSO(0), and h ENSO(–1). Hatching in e–h indicates statistical significance at the p < 0.05 level
