Predictability errors and ENSO–IOD relationship in CPSv2 and CPSv3. Predictability errors of SST averaged over 10° S–10° N in a CPSv2 and b CPSv3 at different lead months. c The relationship of concurrent Niño3.4 index and DMI from May to November in observations (black line) and predictions using CPSv2 (blue line) and CPSv3 (purple line). d–f The correlation between SON Niño3.4 index and concurrent SST in the Indian Ocean in d observations and predictions using e CPSv2 and f CPSv3. c–f are based on predictions starting from May
