Different El Niño, Different Paths of North Equatorial Current

Different types of El Niño have different impacts on the North Equatorial Current Bifurcation and can be extended to ocean circulations in the Pacific and the global climate system.

The latitude of the North Equatorial Current Bifurcation (NECB) impacts a wide range of large-scale ocean behaviors, such as the Kuroshio, Mindanao Current, and the Indonesian throughflow, with far ranging impacts on the ocean and climate system. It’s been known that the NECB latitude responds to El Niño-Southern Oscillation (ENSO), but the relationship is not rigorous.

Wang et al. [2020] make a meaningful start in detailing the impact of the varied ‘flavors’ of El Niño. Hopefully, it will be helpful to improve the simulation and prediction of the local and global climate, and it will also encourage people to develop a more quantitative study of the coupling of the NECB to larger scale forcing.
