摘要：

Discrete auroras are primarily composed of linear elements, whereas diffuse auroras appear in a variety of shapes. Dynamical variations within discrete auroras are characterized by shear, evidently caused by field-aligned currents and charge excesses. In contrast, diffuse, pulsating aurora exhibits little shear, indicating lack of large currents and electric fields associated with this type of aurora. © 1978, Society of Geomagnetism and Earth, Planetary and Space Sciences.
