The impact of ENSO on regional rainfall is nonlinear, which can have a severe impact on regional hydroclimate variability. In this new paper with @andrewkingclimate.bsky.social and @drjobrown.bsky.social, we assess CMIP6 models in capturing this nonlinearity - doi.org/10.1029/2024...
Figures describing the nature of the asymmetry of ENSO-rainfall teleconnections in two regions - East Australia and South-East Asia. East Australia experiences a stronger wet response during La Niña compared to the dry response during an El Niño, leading to a wet-type asymmetry. South-East Asia however, the effect is opposite with a stronger dry response during El Niño leading to a dry-type asymmetry Regional and performance of models in capturing the linear nature of ENSO-rainfall teleconnections for a July-June average.
