From: Indian Ocean Dipole in CMIP5 and CMIP6: characteristics, biases, and links to ENSO
Inter-model correlation of climatological SON average SST to IOD strength (calculated as SON DMI standard deviation) in (a) CMIP5, (e) CMIP6, and ENSO strength (calculated as DJF Niño3.4 standard deviation) in (b) CMIP5 and (f) CMIP6. Significant correlations (p < 0.05) are stippled. Climatological SON mean SST overlaid in contours, interval = 2 °C. Mean SST bias relative to HadISST (1950–2005) for (c) CMIP5, and (g) CMIP6 (stippled where differences are significant at a 95% level binomial test). The difference in inter-model standard deviation of SST climatology between CMIP6 and CMIP5 is shown in (d). The difference between climatological SST bias is shown in (h); stippled where CMIP5 and CMIP6 SST climatology are significantly different at a 90% level based on a Student’s t-test.
