Fig. 2: CCM scores of monthly teleconnection indices with ROS days per month.

a Southern Oscillation Index (SOI). b Tropical North Atlantic (TNA) Index. c Pacific Decadal Oscillation (PDO) Index. d East Central Tropical Pacific Sea Surface Temperature (NINO SST 3.4). e North Pacific (NP) Index. f Pacific North American (PNA) Index. g Arctic Oscillation (AO). h North Atlantic Oscillation (NAO) Index. The higher (closer to +1) the value, the stronger the causal connection. Note that only stations where causality exists (i.e., stations where the CCM converges) are shown.
