It is a minimum during March and April when there is little evidence of any E-going sets in the W,and it is only evident from 20° W in the E.During the late spring a small area of E-going sets appears off the NE coast of Brazil between the equator and about 4° N.This gradually moves NW and expands E over the following few months emerging with an extension to the W of the Guinea Current.By the late summer and early autumn the Counter-current is at its maximum extent from near 50° W to its confluence with the Guinea Current in 20° W.During November and December the Equatorial Currents tend to merge near 30° W.A slow contraction of both the E and W sections
of the Counter-current takes place over the following months to the spring minimum.Constancies in the Counter-current are mostly moderate or high and average rates are between 1 and 1/2knots.The width of the Counter-current varies continuously but is usually between 4° and 6° of latitude and is centred at about 7°N.
After passing the Strait of Belle Isle and the E coast of Newfoundland,the Labrador Current covers the whole of the Grand Banks except,during summer,the extreme S part.

在3-4月间是最低值,在西半球没有东移迹象,只是在东半球20度西起有明显迹象,在春季末期,在巴西东北沿岸的赤道与北纬4度之间出现小范围的东移迹象,在接下来的几个月里,随着几内亚洋流向西的延伸,这种现象会逐渐向西北移动,并向东延伸,到夏末秋初,来自西经50度的逆流达到最强,并在西经20度与几内亚洋流交汇,在11-12月间,赤道洋流在西经30度附近交汇,并在东西半球慢慢消失,接下来的数月至春末,逆洋流开始形成,逆流的强度大多是中,高级别,平均1-1.5节流速(1/2可能是1-1/2),逆流宽度(范围)多变,但通常在纬度4-6度之间,以北纬7度为中心,穿过belle isle 海峡,在纽芬兰的东海岸,拉布拉多洋流覆盖了除grand banks(可能是大湖区域)的整个区域,在夏天达到顶峰
