Northwestern Pacific oceanic circulation shaped by ENSO

The Pacific circulation is significantly influenced by ENSO. This study found that during El Niño years, the North Equatorial Current, subtropical Kuroshio and Kuroshio Extension strengthen. These responses are more pronounced during Central Pacific El Niño and are expected to intensify under future global warming.

Relationship Between Northwest Pacific Ocean Circulation and ENSO. Shading represents the regression of sea surface velocity onto the Oceanic Niño Index during 1993–2022. Streamlines and arrows indicate the mean sea surface circulation, black dots denote statistically significant at the 99% confidence level. Red line marks the boundary between tropical and subtropical regions (20°N). During El Niño events, the North Equatorial Current (NEC), Mindanao Current (MC), Indonesian Throughflow (ITF), North Equatorial Countercurrent (NECC), Subtropical Kuroshio Current (SKC), and Kuroshio Extension (KE) are enhanced, whereas the Tropical Kuroshio Current (TKC) weakens.
