The solar wind is supersonic and passes through a bow shock where the direction of flow is changed so that most of the solar wind plasma is deflected to either side of the magnetopause, much like water is deflected before the bow of a ship. The zone of shocked solar wind plasma is the magnetosheath. At Earth and all the other planets with ...
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 ...
The latitude ranges for the Roaring Forties and similar winds are not consistent: all shift towards the South Pole in the southern summer, and towards the Equator in the southern winter. [2] Wellington , the capital of New Zealand, is known as "Windy Welly" because it is one of the few cities situated in these gusty latitudes.
The winds that flow to the west (from the east, easterly wind) at the ground level in the Hadley cell are called the trade winds. Though the Hadley cell is described as located at the equator, it shifts northerly (to higher latitudes) in June and July and southerly (toward lower latitudes) in December and January, as a result of the Sun's ...
The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s , a temperature of ~ 100 kilokelvin and a composition that is a close match to the ...
The Sun's wind is called the solar wind. These winds consist mostly of high-energy electrons and protons (about 1 keV) that are able to escape the star's gravity because of the high temperature of the corona. Stellar winds from main-sequence stars do not strongly influence the evolution of lower-mass stars such as the Sun.
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. Ions accelerated by a polarization electric field known as an ambipolar electric field is believed to be the ...
Besides the westerlies, and trade winds, the large surfaces of land also effect the wind, causing cyclones, hurricanes and other deviations to the normal direction of trade wind File usage The following 10 pages use this file:
