From: Indian Ocean Dipole in CMIP5 and CMIP6: characteristics, biases, and links to ENSO

Scatter plots of ENSO strength and IOD strength for different regions of ENSO variability. (a) Niño3.4 DJF standard deviation versus DMI SON standard deviation, (b) Niño3 DJF standard deviation versus DMI SON standard deviation, (c) Niño4 DJF standard deviation versus DMI SON standard deviation. CMIP5 models are indicated with open markers, CMIP6 with filled markers. Correlation coefficients for CMIP5 (red) and CMIP6 (green) are shown in each panel.
