A study using CMIP5 models projects that the East Asian eddy-driven jet (EAEJ) will intensify in a warming climate, with an increase in eddy kinetic energy (EKE) as a key indicator. This intensification is linked to changes in surface stability and the historical state of EKE. CMIP5 models show large variations in their projections, indicating significant model diversity and independence. The EKE increase is associated with reduced low-level Brunt-Väisälä frequency (BVF) and enhanced baroclinicity. The study finds that the future change in EKE is strongly correlated with historical EKE levels, suggesting that models with lower historical EKE are more likely to show stronger future EKE. The results show that EAEJ will experience a slight equatorward shift compared to the poleward shift seen in oceanic storm tracks. The study highlights the importance of understanding EAEJ dynamics in the context of climate change, emphasizing the need for accurate modeling of midlatitude processes in East Asia. The findings suggest that more intense winter storm events are likely in a warming climate. The study also notes that CMIP5 models exhibit considerable intermodel variability, indicating the need for further research to improve model accuracy in simulating East Asian jet dynamics.A study using CMIP5 models projects that the East Asian eddy-driven jet (EAEJ) will intensify in a warming climate, with an increase in eddy kinetic energy (EKE) as a key indicator.
