Etymology
From Germanic *winda-, *wenda-, from a suffixed form *we-nt- of Indo-European *we- ‘blow, gust’. Germanic cognates include Old Frisian wind, Old Saxon wind (Dutch wind), Old High German wint (German Wind), Old Norse vindr (Swedish vind), Gothic 𐍅𐌹𐌽𐌳𐍃. The IE root is also the source of Latin ventus (French vent), Welsh gwynt, Tocharian A want, Tocharian B yente.Pronunciation
- /wɪnd/
Noun
windWind is the flow of air or other gases that compose an atmosphere (including, but
not limited to, the Earth's). It occurs
as air is heated by the Sun and thus rises. Cool air then rushes to
occupy the area from which the hot air has now moved. It could be
loosely classed as a convection current.
Winds are commonly classified by their spatial
scale, their speed, the types of forces that cause them, the
geographic regions in which they occur, and their effect. While
wind is often a standalone weather phenomenon, it can also
occur as part of a storm
system, most notably in a cyclone.
Winds can shape landforms, via a variety of
aeolian
processes.
In human
civilization, wind
has inspired mythology, changed the course
of history, expanded the
range of transport and
warfare, and provided a
power
source for mechanical
work, electricity, and recreation.
Forces
Forces which drive wind or affect it are the pressure gradient force, the Coriolis force, buoyancy forces, and friction forces. When a difference in pressure exists between two adjacent air masses, the air tends to flow from the region of high pressure to the region of low pressure. On a rotating planet, flows will be acted upon by the Coriolis force, in regions sufficiently far from the equator and sufficiently high above the surface.The two major driving factors of large scale
global winds are the differential heating between the equator and
the poles (difference in absorption of solar energy
between these climate
zones), and the rotation of the planet.
Components of wind
Winds defined by an equilibrium of physical
forces are used in the decomposition and analysis of wind profiles.
They are useful for simplifying the atmospheric equations
of motion and for making qualitative arguments about the
horizontal and vertical distribution of winds. Examples are:
- Geostrophic wind (wind that is a result of the balance between Coriolis force and pressure gradient force; flows parallel to isobars and approximates the flow above the atmospheric boundary layer in the midlatitudes if frictional effects are low)
- Thermal wind (not actually a wind but a wind difference between two levels; only exists in an atmosphere with horizontal temperature gradients, i.e. baroclinicity)
- Ageostropic wind (difference between actual and geostrophic wind; the wind component which is responsible for air "filling up" cyclones over time)
- Gradient wind (like geostrophic wind but also including centrifugal force)
Classification
There are global winds, such as the wind belts
which exist between the atmospheric circulation cells. There are
upper-level winds which typically include narrow belts of
concentrated flow called jet streams.
There are synoptic
scale winds that result from pressure differences in surface
air masses in the middle latitudes, and there are winds that come
about as a consequence of geographic features, such as
the sea
breezes on coastlines or canyon breezes near mountains.
Mesoscale
winds are those which act on a local scale, such as gust fronts. At the
smallest scale are the microscale winds, which blow on a scale of
only tens to hundreds of meters and are essentially unpredictable,
such as dust devils
and microbursts.
Wind terms
Gusts are inconstant winds. Unlike relatively constant winds, such as the Chinook wind, gusting winds are characterized by the apparent rapid change in the force and/or direction of the wind. The wind appears, to those who experience it, to come in blasts of varying strength with brief lulls between. Such a blast is known as a gust.A squall is a sudden, sharp
increase in wind speed which usually is associated with active
weather, such as rain showers, thunderstorms, or heavy snow.
Squalls refer to an increase in the non-sustained winds over an
extended time interval, as there may be lower gusts during a squall
event.
Named winds
In modern usage, many local
wind systems have their own names.
Local winds
seealso List of local windsSome local winds blow only under certain
circumstances, i.e. they require a certain temperature
distribution.
Differential heating is the motive force behind
land
breezes and sea breezes
(or, in the case of larger lakes, lake breezes), also known as on-
or off-shore winds. Land absorbs and radiates heat faster than
water, but water releases heat over a longer period of time. The
result is that, in locations where sea and land meet, heat absorbed
over the day will be radiated more quickly by the land at night,
cooling the air. Over the sea, heat is still being released into
the air at night, which rises. This convective motion draws the
cool land air in to replace the rising air, resulting in a land
breeze in the late night and early morning. During the day, the
roles are reversed. Warm air over the land rises, pulling cool air
in from the sea to replace it, giving a sea breeze during the
afternoon and evening.
Mountain
breezes and valley
breezes are due to a combination of differential heating and
geometry. When the sun rises, it is the tops of the mountain peaks
which receive first light, and as the day progresses, the mountain
slopes take on a greater heat load than the valleys. This results
in a temperature inequity between the two, and as warm air rises
off the slopes, cool air moves up out of the valleys to replace it.
This upslope wind is called a valley breeze. The opposite effect
takes place in the afternoon, as the valley radiates heat. The
peaks, long since cooled, transport air into the valley in a
process that is partly gravitational and partly convective and is
called a mountain breeze.
Forested areas are less windy than plains and
cities because the trees disrupt wind patterns. Trees are defined
to have a dampening effect on wind speeds in that they reduce the
partial derivative of pressure differences across non-infinitively
occupying plain. Further effects of trees wind reducing
capabilities is in the fact that trees bend in the wind.
Considering the mass of a tree in comparison to air particles it is
highly predicable that much of the total energy of the wind is lost
in kinetic energy to the trees.
Mountain breezes are one example of what is known
more generally as a katabatic
wind. These are winds driven by cold air flowing down a slope,
and occur on the largest scale in Greenland and
Antarctica. Most
often, this term refers to winds which form when air which has
cooled over a high, cold plateau is set in motion and descends
under the influence of gravity. Winds of this type are common in
regions of Mongolia and in
glaciated locations.
Because katabatic refers specifically to the
vertical motion of the wind, this group also includes winds which
form on the lee side of mountains, and heat as a consequence of
compression. Such winds may undergo a temperature increase of 20
°C (68
°F) or
more, and many of the world's "named" winds (see #Named Winds
above) belong to this group. Among the most well-known of these
winds are the chinook of
Western Canada and the American Northwest, the Swiss foehn,
California's infamous Santa Ana
wind, and the French Mistral.
The opposite of a katabatic wind is an anabatic
wind, or an upward-moving wind. The above-described valley
breeze is an anabatic wind.
A widely-used term, though one not formally
recognised by meteorologists, is orographic wind. This refers
to air which undergoes orographic lifting. Most often, this is in
the context of winds such as the chinook or the föhn, which undergo
lifting by mountain ranges before descending and warming on the lee
side.

Mythology
see Wind god As a natural force, the wind was often personified as one or more wind gods or as an expression of the supernatural in many cultures.In ancient Greek
mythology, the four winds were personified as gods, called the
Anemoi -
Boreas, Notos, Euros and Zephyros. Aeolus, in varying
interpretations the ruler or keeper of the four winds, has also
been described as Astraeus, the god
of dusk who fathered the four winds with Eos, goddess of
dawn.
The Ancient
Greeks also observed the seasonal change of the winds, as
evidenced by the Tower
of the Winds in Athens.
The winds are discussed in the Bible:
History
Kamikaze (神風) is a Japanese word, usually translated as divine wind, believed to be a gift from the gods. The term is first known to have been used as the name of a pair or series of typhoons that are said to have saved Japan from two Mongol fleets under Kublai Khan that attacked Japan in 1274 and again in 1281.Protestant
Wind is a name for the storm that deterred the Spanish
Armada from an invasion of England in 1588 or
the favourable winds that enabled William
of Orange to invade England in 1688.
Transportation
- Sailing ship
- While aircraft usually travel under an internal power source, tail winds affect airspeed, and in the case of hot-air balloons and other lighter-than-air vehicles, wind may play a significant role in their propulsion.

Culture
Wind has featured in human cultural works, including art, poetry, music, theatre, novels, films, and television.'Westron wynde, when wilt
thou blow,
The small raine down can
raine.
Cryst, if my love were in my
armes
And I in my bedde
again!'An anonymous poem The
Western Wynde dating from before the 16th
century
Recreation
Wind figures prominently in several popular
sports, including recreational sailing, windsurfing, and kiteboarding. Finally, wind
enables the simple pleasure of flying a kite.
Role in the natural world
Wind has a very important role in aiding plants
and other immobile organisms in dispersal of seeds, spores, pollen,
etc. Although wind is not the primary form of seed dispersal in
plants, it provides dispersal for a large percentage of the biomass
of land plants.
The study of wind
The Beaufort wind
force scale is an empirical measure for describing wind speed
based mainly on observed sea conditions.
Meteorological instruments to measure wind speed and/or direction
Wind direction is reported by the direction from which it originates. For example, a northerly wind blows from the north to the south.Local sensing techniques:
- Anemometer (measures wind speed, either directly, e.g. with rotating cups, or indirectly, e.g. via pressure differences or the propagation speed of ultrasound signals)
- Rawinsonde (GPS-based wind measurement is performed by the probe)
- Weather balloon (passive measurement, balloon position is tracked from the ground visually or via radar; wind profile is computed from drift rate and the theoretical speed of ascent)
- Weather vane (used to indicate wind direction)
- Windsock (primarily used to indicate wind direction, may also be used to estimate wind speed by its angle)
- Pitot tubes
Remote
sensing techniques:
- SODAR
- Doppler LIDARs and RADARs can measure the Doppler shift of electromagnetic radiation scattered or reflected off suspended aerosols or molecules. This measurement can be directly related to wind velocity.
- Radiometers and radars can be used to measure the surface roughness of the ocean from space or airplanes. This measurement can be used to estimate wind velocity close to the sea surface over oceans.
