respectively. In addition, there is also an intermittent surface current (usually appears in the west Pacific) which flows from west to east along the equator. Delcroix et al. (1992) and Johnson et al. (2000) suggested that this current differs from the known Equatorial Undercurrent (EUC) and it is caused mainly by a westerly wind burst. So they referred to it as the “eastward equatorial current" to clarify this difference. To disagree with them, Wang and Wu (2013) suggested that it is the surface part of the shoaled EUC. In addition, in a study of El Niño by Lagerloef et al. (2003) they simply called this a “surface current." In fact, in the documented studies on ENSO, together with the westward NSEC, it is usually included in the vague calling “zonal current" or “zonal advection" (Collins et al. 2010). Thus, there is a necessity to give an appropriate name to this surface current regardless of its relationship with the EUC (because the word “undercurrent" is improper for this case). Notice that all of the defined Currents flow from east to west, all of the Countercurrents flow from west to east and this one lies between the NECC and SECC, we refer
