Prevailing winds. Winds are part of Earth's atmospheric circulation. Global surface wind vector flow lines colored by wind speed from June 1, 2011 to October 31, 2011. In meteorology, prevailing wind in a region of the Earth 's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in ...
Wind. Cherry tree moving with the wind blowing about 22 m/sec (about 79 km/h or 49 mph) Sound of wind blowing in a pine forest at around 25 m/sec, with gust alterations. 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 ...
Atmospheric circulation. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.
A zonal region on the globe. Zonal and meridional flow are directions and regions of fluid flow on a globe. Zonal flow follows a pattern along latitudinal lines, latitudinal circles or in the west–east direction. [1] Meridional flow follows a pattern from north to south, or from south to north, along the Earth's longitude lines, longitudinal ...
Burle (north wind which blows in the winter in south-central France) Cers (strong, very dry northeasterly wind in the bas- Languedoc region in southern France) Cierzo (cool north/northwesterly wind on Ebro Valley in Spain) Crivăț (strong, very cold north-easterly wind in Moldavia, Dobruja, and the Bărăgan Plain parts of Romania.)
Wind direction is generally reported by the direction from which the wind originates. For example, a north or northerly wind blows from the north to the south; [1] the exceptions are onshore winds (blowing onto the shore from the water) and offshore winds (blowing off the shore to the water). Wind direction is usually reported in cardinal (or ...
In oceanography, a gyre (/ ˈdʒaɪər /) is any large system of ocean surface currents moving in a circular fashion driven by wind movements. Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the wind stress curl (torque). [1]
The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.
