Acknowledgments
The authors acknowledge the World Climate Research Programme’s Working Group on Coupled Modelling, which is responsible for CMIP6, and the modeling groups (listed in method of this paper) for producing and making model outputs publicly available. We also thank John Dunne for making Global Daily 1° × 1° SST outputs of GFDL-ESM4 publicly available upon request and sharing thoughts on discussing the possible drivers of biases in simulating warm-season marine heatwave properties in GFDL-ESM4.
