Winds are part of Earth's atmospheric circulation. The westerlies (blue) and trade winds (yellow and brown) 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 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 westerlies (blue) and trade winds (yellow and brown) The general atmospheric circulation. Trade winds (red), westerlies (white) and the South Pacific anticyclone (blue) [1] The westerlies, anti-trades, [2] or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
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 ...
A difference in air pressure causes an air displacement and generates the wind. The Coriolis force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. [1] It is also referred as the geostrophic wind. [2]
A convective planetary boundary layer is a type of planetary boundary layer where positive buoyancy flux at the surface creates a thermal instability and thus generates additional or even major turbulence. (This is also known as having CAPE or convective available potential energy; see atmospheric convection.) A convective boundary layer is ...
A hodograph is a diagram that gives a vectorial visual representation of the movement of a body or a fluid. It is the locus of one end of a variable vector, with the other end fixed. [1] The position of any plotted data on such a diagram is proportional to the velocity of the moving particle. [2] It is also called a velocity diagram.
Rossby waves, also known as planetary waves, are a type of inertial wave naturally occurring in rotating fluids. [1] They were first identified by Sweden-born American meteorologist Carl-Gustaf Arvid Rossby in the Earth's atmosphere in 1939.
