Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and th ...

In classical terminology, Aeolian winds, or winds producing Aeolian action, are winds which produce geologic changes. Modern tornadoes and hurricanes might at times be considered to produce such changes. Largescale erosion, dune formation, and other geologic and topographic effects influenced by wind are still referred to as aeolian activity. ...

A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air.

A wind tunnel is a research tool developed to assist with studying the effects of air moving over or around solid objects. Air is blown or sucked through a duct equipped with a viewing port anod instrumentation where models or geometrical shapes are mounted for study. Various techniques are then used to study the actual airflow around the geometry and compare it with theoretical results, which must also take into account the Reynolds n ...

Wind power is the kinetic energy of wind, or the extraction of this energy by wind turbines. In 2004, wind power became the least expensive form of new power generation, dipping below the cost per kilowatt-hour of coal-fired plants[1]. Wind power is growing faster than any other form of electrical generation, at about 37%[2], up from 25% growth in 2002. In the late-1990s, the cost of wind power was about five times what it is in 2005, and that downward trend is expected to continue as larger multi-megawatt turbines are mass-produced.[ ...

A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator. This article discusses the conversion machinery. See the broader article on wind power for more on turbine placement and controversy, and in particular see the wind energy section of that article for an understanding of the temporal distribution of wi ...

Wind chill is the apparent temperature felt on exposed skin due to the combination of air temperature and wind speed. Except at higher temperatures, where wind chill is considered less important, the wind chill temperature (often incorrectly called the "wind chill factor") is always lower than the air temperature, because any wind increases the rate at which moisture evaporates from the skin and carries heat away from the body. The phase change of water (in sweat) from liquid to vapor requires that the molecules reach a higher energy state. That energy is acquired by absorbing heat from surr ...

A Mighty Wind is a 2003 mockumentary about a folk music reunion concert and the three groups that must come together to perform on national television for the first time in years. The film was directed (and co-written) by prolific "mockumentarian" Christopher Guest. The title probably alludes to the folk standard Wasn't That A Mighty Storm and an article of the same name[1], subtitled The World's Hippest Geezers, about the reunion, in 2000, of the aging original members of the Jim Kweskin Jug Band, including Fritz ...

A wind gradient describes the change in velocity and/or direction of the wind in a certain direction. There is always a significant wind gradient just above the ground, where the wind gets stronger with increasing altitude. The technique of dynamic soaring allows birds and sailplanes to gain energy from wind gradients. Vertical wind gradients affect starting and landing aircraft: It is part of the reason why airplanes land and take off into the wind. During climb into increasing wind, the airspeed increases, allowing the plane to gain energy

Wind shear is a difference in wind speed or direction between two points in the atmosphere. Depending whether the two points are at different altitudes or at geographically different locations, shear can be either vertical or horizontal. Wind shear can affect aircraft airspeed during take off and landing in disastrous ways. An explanation in regard to vertical wind shear can be seen here: (wind gradient). It is also a key factor governing the severity of thunderstorms. An additional hazard is turbulence often associated with wind shear. Wind shear also ...

Chinook winds, often just called chinooks, are a wind pattern observed in midwestern North America, named for the Chinook Indians. In popular myth, Chinook is supposed to mean "snow eater", as a strong Chinook can make a foot of snow all but vanish inside of one day. The snow partially melts, and partially evaporates in the dry wind. The true origin of the name is that "Chinook Wind" in the local argot of the fur trade era meant that the wind came from the direction of the country of the Chinooks (the lower Co ...

A wind quintet, also sometimes known as a woodwind quintet, is a group of five wind players (most commonly flute, oboe, clarinet, horn and bassoon). The term also applies to a composition for such a group. Unlike the string quartet with its homogeneous blend of color, the instruments in a wind quintet differ from each other considerably in technique, idiom, and timbre. The modern wind quintet sprang from the ensemble favored in the court of Joseph II in late 18th century Vienna: 2 clarinets, 2 horns, 2 oboes, and 2 bassoons. Th ...

Apparent wind is the breeze felt by an observer. It is created both by the movement of the observer, and by the true wind. For a stationary observer, both apparent wind and true wind are the same. Apparent wind is calculated by the sum of two vectors. The first vector is the true wind velocity. The second vector is the velocity of the observer. By adding these two vectors together, one can determine the apparent wind. In sailing, and especially in sailboat racing, apparent wind is a vitally important factor, since it termines the points of sail on whic ...

The trade winds are a pattern of wind found in bands around the Earth's equatorial region. The trade winds are the prevailing winds in the tropics, blowing from the high-pressure area in the horse latitudes towards the low-pressure area around the equator. The trade winds blow predominantly from the northeast in the northern hemisphere and from the southeast in the southern hemisphere. Their name derives from the Old English 'trade', meaning "path" or "track," and thus the phrase ...

Zonda wind (in Spanish, viento zonda) is a regional term for the föhn wind that often occurs on the eastern slope of the Andes, in Argentina. The Zonda is a dry wind (often carrying dust) which comes from the polar maritime air, warmed by descent from the crest, which is some 6,000 m (18,000 ft) above sea level. It may exceed a velocity of 40 km/h (25 mph). The terms also describes a hot, humid north wind in the Pampas, in advance of a depression moving eastwards, and preceding the pampero. This wind is also called the

An anabatic wind, from the Greek anabatos, verbal of anabainein meaning moving upward, is a wind which blows up a steep slope or mountain side. These winds typically occur during the daytime in calm sunny weather. A hill or mountain top will be radiatively warmed by the Sun which in turn heats the air just above it. Air at a similar altitude over an adjacent valley or plain does not get warmed so much because of the greater distance to the ground below it. The effect may be enhanced if the lower lying ground ...

Wind winnowing is a method developed by ancient cultures for agricultural purposes. It involves taking a basket of grain and chaff and tossing the contents into the air, thus causing the chaff to blow away while the heavier grains would fall back into the basket.

"Candle in the Wind" is a song with music by Elton John and lyrics by Bernie Taupin. Originally written in 1973, a later version of the song became the world's best-selling single of all time. The original version was found on Elton John's 1973 album Goodbye Yellow Brick Road. The lyrics of the song are a sympathetic portrayal of the life of Marilyn Monroe (the song's opening line "Goodbye Norma Jean" refers to Monroe's real name) and condemn exploitation by those around her, using the metaphor of a candle extinguished p ...
