根据1999 - 2005年在23-29°W拍摄的11个跨赤道船舶剖面和2004年2月至2005年5月在23°W赤道部署的一对系泊声学多普勒海流廓线仪的数据，研究了热带大西洋中部700米以上的纬向赤道环流。赤道上的观测结果表明，在赤道潜流之下存在两个平均向西的赤道中间流核。与2002年在同一位置的系泊观测相反，系泊期间的季节内变化主要是纬向而不是纬向速度波动。
The zonal equatorial circulation of the upper 700 m in the central tropical Atlantic is studied based on 11 cross‐equatorial ship sections taken at 23–29°W during 1999 to 2005 and on data from a pair of moored Acoustic Doppler current profilers deployed on the equator at 23°W during February 2004 to May 2005. The observations on the equator reveal the existence of two mean westward cores of the Equatorial Intermediate Current below the Equatorial Undercurrent. In contrast to the 2002 moored observations at the same position the intraseasonal variability during the mooring period is dominated by zonal instead of meridional velocity fluctuations.
