Fig. 4: Correspondence between gridded annual SWA and Large Scale Climate Indices across positive and negative hotspots.

In all panels blue and red bars show the percentage of the areas within positive and negative hotspots that have significant dependence (p-value ≤ 0.05) with Large Scale Climate Indices (LSCI) – see Supplementary Fig. 10 for the location of hotspot areas. LSCIs considered include (from left to right in each panel), the Pacific Decadal Oscillation (PDO), Northern Oscillation Index (NOI), Pacific North American index (PNA), North Atlantic Oscillation (NAO), North Pacific Pattern (NPP), Western Hemisphere Warm Pool (WHWP), Atlantic Multidecadal Oscillation (AMO), Solar flux, Western Pacific Index (WPI), Global Mean Surface Temperature (GMST), Pacific Warm Pool Area Average (PWPAA), and Artic Sea Ice Area Average (ASIAA).
