Polar Wind

Polar wind

The polar wind or plasma fountain is a permanent outflow of plasma from the polar regions of Earth's magnetosphere. Conceptually similar to the solar wind, it is one of several mechanisms for the outflow of ionized particles. Ions accelerated by a polarization electric field known as an ambipolar electric field is believed to be the primary cause of polar wind. Similar processes operate on other planets.

Wind

Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The study of wind is known as anemology.
