(a) Mean zonal Argo geostrophic currents vertically averaged between 240 and 340 m in the tropical North Pacific Ocean. The schematic axes of the major subsurface zonal currents, the Northern Subsurface Countercurrent (NSCC, a.k.a. Tsuchiya Jet) and the North Equatorial Subsurface Current (NESC) are marked. The mooring location and the meridonal sections of Argo profiles used in this paper (b–d and Fig. 4) are also marked by a solid square and dashed lines, respectively. Mean zonal Argo geostrophic currents in the meridional sections of (b) 150° E, (c) 165° E, and (d) 130° W in the western, central and eastern Pacific Ocean, respectively. The major zonal surface (North Equatorial Current, NEC; North Equatorial Countercurrent, NECC) and subsurface (NSCC; NESC) currents in the northern equatorial Pacific Ocean are marked in (b–d). The mean currents are averaged from the monthly Argo geostrophic currents from 2014 to 2018. The currents are averaged within longitudinal range of 5° close to the sections. The grey contours mark the potential density surfaces (minus 1,000 kg m−3). Unit of the density is kg m−3. The positive/negative values stand for eastward/westward currents. Only the westward currents are shaded in color to highlight the location of the NESC in (a). Unit of currents is cm s−1. The figure is generented by MATLAB software version R2019b (https://www.mathworks.com/).
