auroral zone meaning in Hindi

Examples

1. A geomagnetic storm expands the auroral zone to lower latitudes.
2. Radiation received also varies with geographical location ( polar, auroral zones, mid-latitudes, and equatorial regions ).
3. Poker Flat lies under the auroral zone, a doughnut-shaped expanse of sky around Earth's geomagnetic pole near Thule, Greenland.
4. Furthermore, these networks must have overlapping Fields-of-View that span latitudes from the polar region, through the auroral zone, to sub-auroral latitudes.
5. AE index is compiled from geomagnetic disturbances at 12 geomagnetic observatories in and near the auroral zones and is recorded at 1-minute intervals.
6. The AE index indicates the intensity of geomagnetic substorms except during a major geomagnetic storm when the auroral zones expand equatorward from the observatories.
7. The auroral zone in the northern hemisphere passes over the upper half of Alaska and Canada, as well as northern Scandivania, Norway, Sweden and Finland.
8. The southern counterpart, the Aurora Australis or the Southern Lights, has features that are almost identical to the Aurora Borealis and changes simultaneously with changes in the northern auroral zone.
9. In the high latitude ionosphere ( or auroral zones ), the Birkeland currents close through the region of the auroral electrojet, which flows perpendicular to the local magnetic field in the ionosphere.
10. This location was chosen because it was important to carry out a sounding rocket programme in the auroral zone, and essential that ESRO equip itself with a suitable range in the northern latitudes.
