(a) Baroclinic modes functions (first three), and (b) progressive superpositions of the first 3 baroclinic modes functions scaled by equivalent depths compared with the superposition of the first 10 scaled baroclinic mode functions. The steady-state solution of the linear continuously stratified model (LCSM) in the meridional section of 170° W with first 3 (c) or 10 (d) baroclinic modes. The main zonal currents are marked in (c) and (d), including the North and South Equatorial Currents (NEC, SEC), the North Equatorial Countercurrent (NECC), the Equatorial Undercurrent (EUC), the Equatorial Intermediate Current (EIC), the Northern and Southern Subsurface Countercurrents (NSCC, SSCC), and the NESC. Colors stand for the magnitude of the zonal velocity, blue for the westward currents and red for the eastward currents, respectively. The baroclinic modes functions are normalized by values at the surface. Unit of the zonal velocity is cm s−1. The figure is generented by MATLAB software version R2019b (https://www.mathworks.com/).
