Fig. 2: Changes in frequency and magnitude in each type of El Niño.
From: More frequent central Pacific El Niño and stronger eastern pacific El Niño in a warmer climate
a Ratios of frequencies of CP El Niño events relative to the sum of the total number of CP and EP El Niño events. b The composites of Niño3 SSTA for EP El Niño events, and c Niño4 SSTA for CP El Niño events. Red and blue bars represent the 20th and 21st centuries, respectively. The error bars indicate the 95% confidence level using the bootstrap method (Methods). The units are [°C] for b, c.
