  abstract = {{A}n analysis of numerous meridional {XBT} sections near 28°{W} reveals that the geostrophic {N}orth {E}quatorial {C}ountercurrent ({NECC}) continues to flow eastward throughout the year, fatest in fall and slowest in spring. {D}rifting buoys and historical ship drifts show that the near-surface {C}ountercurrent reverses each spring even when systematic errors due to windage are taken into account. {T}he seasonally fluctuating winds drive an {E}kman surface current that is eastward in fall, adding to the geostrophic current, and westward in spring, countering and overwheling the geostrophic current. {T}he reversal of the countercurrent in spring occurs in the near-surface layer and is driven by the {N}ortheast trades. {T}hus the near-surface velocity in the countercurrent is determined by a competition between local wind stress and the larger field of wind stress curl, both of which have large seasonal variations in the {T}ropical {A}tlantic.
