Polar wind - Wikipedia
The polar wind or plasma fountain is a permanent outflow of plasma from the polar regions of Earth's magnetosphere. [2]: 29 Conceptually similar to the solar wind, it is one of several mechanisms for the outflow of ionized particles.

2014年2月10日 · Polar Winds. April 5, 2018. Context image. This VIS image shows 'streamers' of clouds created by katabatic winds at the north polar cap. Katabatic winds are created by cold air sinking at the pole and then speeding along the ice surface towards the edge of the polar cap.
Polar Winds - Kids Earth Science
Polar winds begin near the North and South Poles. Frigid air in the winter sinks toward the ground creating a high pressure area at the poles. These winds occur in both hemispheres.
