Abstract Given the essential implications of Kuroshio Extension (KE) bimodality on oceanic dynamical environment and climate, present study investigates targeted observation schemes, based conditional nonlinear optimal perturbation (CNOP) method a reduced‐gravity shallow‐water model, to improve forecast skills transition processes KE bimodal states. To obtain suitable observing array, with different numbers sites distances between two sites, are designed. Furthermore, demonstrate superiority...
Abstract This study investigates the short‐term transition process between Kuroshio Extension (KE) stable and unstable states (bimodality) based on eddy energetics analysis. The local dynamic mechanisms modulating KE transitions are revealed by exploring kinetic energy (EKE) variability. During stable‐to‐unstable (low‐to‐high EKE level; SU), baroclinic instability is major source of growth. As negative sea surface height anomaly (SSHa) signal propagates westward near domain, jet downstream...
