Do CMIP6 Models Capture Seasonal and Regional Differences in the Asymmetry of ENSO-Precipitation Teleconnections?

The impact of ENSO on regional rainfall is often opposite between these two major phases of ENSO in various regions around the world. However, the two ENSO patterns of rainfall are not always mirror images of one another. Essentially, the rainfall response can often be higher or lower in magnitude during one phase compared to the other, which is often described as an asymmetric response of precipitation to ENSO. We assess the ability of 50 coupled climate models in simulating the seasonal and regional differences in asymmetric response using observations and reanalysis data sets as reference. Model performance is found to be poor across all regions and season, mainly because of the inability of the models in simulating the observed skewness in the regional precipitation anomaly distribution
