Mean surface eddy kinetic energy (EKE, cm2/s2) for (a) AVISO_ssha, (b) IAP-LICOM_JRA_ssha, (c) IAP-LICOM_JRA_uv, (d) FSU-HYCOM_JRA_uv, (e) AWI-FESOM_JRA_uv, and (f) NCAR-POP_JRA_uv during 1993–2018. The black contours in (a)–(f) are the global spatial standard deviation (STD; labeled in each panel) for each mean EKE distribution. The spatial pattern correlation coefficients (SPCCs) between each simulation and AVISO_ssha are also labeled in the top…
