What excatly creates wind?

Question

I was just wondering about it, how is it that wind begins somewhere in the oceans, i mean what gives air the movement to create wind? I know that winds go in different directions and so they constantly circulate pushing the other currents so that they keep on going, but what is it that created the motion in the first place? the Earth's position?, something to do with the north and south poles?.......

Thanks in advance!

Answer 1

The pressure gradient is mainly responsible for the creation of wind.Coriolis force, frictional force,turbulence etc only affect the wind flow .They do not create it.
You may be knowing that air in motion is called wind.Due to the differntial heating(due to many local factors) of the land area as well as sea area by the sun,low pressure area and high pressure areas are created on many places over the earth's surface.Because of this, pressure gradients are produced between high pressure areas and a low pressure areas and this forces the air to move towards low pressure areas.
Even the global winds consisting of Hadley cell,Ferner cell and Polar cells are also due to the temperature gradient from the Equator towards the poles.Maximum solar radiation is received over the equatorial regions and minimum quantity of it over the poles creating the temperature gradient..This temperature gradient in turn is responsible for the three pressure belts and these pressure belts produce three pressure gradients between the equator and the poles on both sides of the equator creating trade winds,westerlies and polar easterlies.

Answer 2

You mean- You dont buy the "breath of the gods " theory?

The winds are caused by the movement o air from high pressure to low pressure aeas of the earth, and this movement is caused by two things

variation in temperature of the earth from heat of the sun and the earths rotation.

Answer 3

Tempreture differences. Hot air rizes. Can't have a vacuum so the air moves in... And then there are the coriolus effects that trun winds.

in simple terms

Wind is the result of different forces acting on a parcel of air.
