计算了极向强电场对夜间电离层E区的影响。结果表明，彼得森和霍尔电导率的实质性变化，从而减少了磁层源看到的电离层电负载。看来，相对较大的电场可以存在于没有伴随的大型场向电流，只要下面的电离层仍然在黑暗中和/或高能粒子降水是不存在的。
Calculations have been made of the effects of intense poleward-directed electric fields upon the nighttime ionospheric E-region. The results show the Pedersen and Hall conductivities are substantially changed, thereby decreasing the ionospheric electrical load seen by magnetospheric sources. It appears that relatively large electric fields can exist in the absence of accompanying large field-aligned currents, as long as the underlying ionosphere remains in darkness and/or energetic particle precipitation is absent.
