Decadal variability of eddy kinetic energy in the subtropical Northeast Pacific

Ocean mesoscale eddies, characterized by substantial eddy kinetic energy (EKE), are ubiquitous throughout the global ocean and play an essential role in ocean circulation, climate, and biogeochemistry. In the North Pacific, high and variable EKE is primarily concentrated in the western Subtropical Gyre. In contrast, the EKE levels in the Subtropical Northeast Pacific are relatively lower. Nevertheless, the EKE in this region remains comparable to the local mean kinetic energy and exhibits signif
