(Qiu and Chen, 2010) • North Equatorial Current bifurcation (NECB) • Zonally distributed wind stress curl
STCC (Qiu and Chen, 2010) • STCC, subtropical countercurrent • Ekman convergence forcing, which associated with meridional temperature gradient and zonal geostrophic velocity
Fig. Comparison between the interannually-varying Ekman forcing term and the interannually-varying EKE time series in the STCC band.
(Qiu and Chen, 2010) Fig. (B) Eddy kinetic energy calculated from the satellite altimeter SSH data from October 1992 to September 2008. White contours denote the 4000-m isobaths..
Fig. (A) Lagged correlation between the SSHa (32o-34oN) and the one-year running mean PDO index. (B) Same as (A) except for the negative, one-year running mean NPGO index. Shaded regions indicate negative correlation coefficients.
