[1]白天赤道电急流的纬向风廓线是根据秘鲁Jicamarca无线电观测站观测到的II型雷达回波的多普勒频移推断的。的推断是基于一个三维静电势模型。该模型包括异常效应，并受到雷达和磁力计数据的约束。计算的纬向风廓线的振幅和相位与上层大气研究卫星（UARS）上WINDII仪器测量的代表性风廓线基本一致。计算的风也有相同的一般特征的纬向风廓线测量火箭载化学释放实验。但是，后者的幅度大于前者。计算的纬向风的时间行为表明，一个向下的阶段进展与一个大致半日周期。
[1] Zonal wind profiles in the daytime equatorial electrojet are inferred from the Doppler shifts of type II radar echoes observed at the Jicamarca Radio Observatory (JRO) in Peru. The inference is based on a three-dimensional electrostatic potential model. The model includes anomalous effects and is constrained by radar and magnetometer data. The amplitude and phase of the calculated zonal wind profiles are in general agreement with representative wind profiles measured by the WINDII instrument on board the Upper Atmosphere Research Satellite (UARS). The calculated winds also have the same general characteristics as zonal wind profiles measured by rocket-borne chemical release experiments. However, the magnitude of the latter are larger than the former. The temporal behavior of the calculated zonal winds suggests a downward phase progression with a roughly semidiurnal period.
