From: Upper-ocean stratification changes control ENSO amplitude shift under sustained global warming
a–c The first, second, and third baroclinic modes are calculated from the eight climate model mean separately during the three periods of 1940-1990 (denoted as P1; red line), 2040-2090 (P2; green line), and 2240-2290 (P3; black line), representing their historical and future distributions under the SSP585 scenario.
