Fig. 3: Inter-model correlation of future projected changes against present-day Indo-Pacific Warm Pool (IPWP) size in SSP5-8.5 scenarios of CMIP6 models.
From: Present-day warm pool constrains future tropical precipitation
a Simulated present-day IPWP size (%) versus future changes in the Pacific zonal sea surface temperature (SST) gradient (dSST), calculated by east-west, negative values indicate reducing of zonal SST gradient. b Future changes in the Pacific zonal SST gradient versus future changes in the Pacific zonal sea level pressure gradient (dSLP). c Future changes in the Pacific zonal sea level pressure gradient versus that of Walker circulation strength (1010 kg s−1). d Future changes of Walker circulation strength (averaging 120°E–180, 700–300 hPa) versus that of CETP (Central-Eastern Tropical Pacific where 5°S–5°N, 160°E–150°W) precipitation (PR, mm day-1). The inter-model correlation coefficients (r), slope, and p value displayed in each panel are statistically significant at the 99% confidence level.
