Modes of pulsating auroras and related geomagnetic pulsations
P(論文) Display modes of pulsating auroras were examined in reference to classifications previously proposed. It is concluded that the pulsating auroras are reasonably classified into, 1) pure pulsations, 2) poleward propagation, 3) streaming along structures, 4) flooding beyond patch boundaries, 5) e...
