| 释义 | auroral adjective uk /ɔːˈrɔː.rəl/ us /ɔːˈrɔːr.əl/ related to the light in the sky of an aurora (= a natural appearance of coloured light in the sky): 极光的 an auroral display一场极光呈现 The lights occur most often in areas known as auroral zones near the magnetic poles.这些光大都常见于靠近两个磁极，被称为极光域的地区。 See aurora We witnessed major auroral activity. An auroral footprint is created by a river of electric current flowing between Jupiter and its volcanic moon, Io. A violent solar flare causes a much wider auroral ring that can sometimes be seen as far as the equator.

During magnetospheric disturbed conditions, this conductivity enhancement becomes much larger, and the auroral regions move equatorward.

The high-level auroral activity may lead to formation of complex hydrocarbon molecules that are carried toward the equator.

Therefore, when using an auroral event as a radio signal reflector, the reflected signal strength and signal intelligibility decreases with increasing transmitting frequency.

Radiation received also varies with geographical location (polar, auroral zones, mid-latitudes, and equatorial regions).

The return current region is where electrons move upward from the ionosphere to close the auroral current circuit.

An auroral electrojet index (measured in nanotesla) is regularly derived from ground data and serves as a general measure of auroral activity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Electric currents originating in such way apparently give auroral electrons their energy.
