PURE ENERGY. “The magnetotail plasma sheet is a highly dynamic and structured region. Plasma flows in this region are not laminar, and during most times the net Earthward plasma flow imposed by the large-scale convection pattern is composed of short-lived (1–10 min) bursts of fast flow while the ambient plasma velocity distribution is very nearly isotropic.”
