a bit windy today

[Scottie]

and it's to get gale force tomorrow.

Got me thinking: where dose the wind come from.??

Must resist :D

[Big Gordy]

I think beans have a lot to answer for you know..:p :rolleyes: :D

[Bumble]

I'm going (almost) seasonal - Sprouts!!!

[john]

traffic?
cows?
i have deleted my third idea:eek:

[Julz]

I'd have to agree with John's 2nd and 3rd suggestions!!;) :D

Wind is the flow (http://en.wikipedia.org/wiki/Flux) of air (http://en.wikipedia.org/wiki/Air). More generally, it is the flow of the gases (http://en.wikipedia.org/wiki/Gas) which compose an atmosphere (http://en.wikipedia.org/wiki/Atmosphere); since wind is not only an Earth (http://en.wikipedia.org/wiki/Earth) based phenomenon (http://en.wikipedia.org/wiki/Phenomenon).
Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the geographic regions in which they occur, or their effect.
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 (http://en.wikipedia.org/wiki/Jet_stream). There are synoptic-scale winds (http://en.wikipedia.org/wiki/Wind#Synoptic_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 (http://en.wikipedia.org/wiki/Geography) features, such as the sea breezes (http://en.wikipedia.org/wiki/Sea_breeze). Mesoscale (http://en.wikipedia.org/wiki/Scale_%28spatial%29) 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 (http://en.wikipedia.org/wiki/Dust_devils) and microbursts (http://en.wikipedia.org/wiki/Microburst).
Forces which drive wind or affect it are the pressure gradient force (http://en.wikipedia.org/wiki/Pressure_gradient_force), the Coriolis force (http://en.wikipedia.org/wiki/Coriolis_force), buoyancy (http://en.wikipedia.org/wiki/Buoyancy) forces, and friction (http://en.wikipedia.org/wiki/Friction) forces. When a difference in pressure (http://en.wikipedia.org/wiki/Pressure) exists between two adjacent air masses, the air tends to flow from the region of high pressure (http://en.wikipedia.org/wiki/High_pressure_area) to the region of low pressure (http://en.wikipedia.org/wiki/Low_pressure_area). On a rotating planet, flows will be acted upon by the Coriolis force (http://en.wikipedia.org/wiki/Coriolis_force), in regions sufficiently far from the equator and sufficiently high above the surface.
The three major driving factors of large scale global winds are the differential heating between the equator and the poles (difference in absorption of solar energy (http://en.wikipedia.org/wiki/Solar_energy) between these climate zones (http://en.wikipedia.org/wiki/Climate_zone)), and the rotation of the planet.
Winds can shape landforms, via a variety of eolian (http://en.wikipedia.org/wiki/Eolian) processes.

hope this helps :p :D :eek:

Sorry, say that again. I seem to have nodded off:cool:

well its now thursday here and its not windy so your forecast was wrong:D
