where does wind come from?

WHAT IS WIND?\n\nMovement of air between pressure systems as they try to balance out is called wind. Air flows from high pressure systems to low ones to try to reach equilibrium. In the constantly developing and changing system of the atmosphere this never actually happens.

Wind will never stop blowing because it is a result of differences in temperature.   If it's hot in one area and cold in the next, the air in between the two areas will rush and swirl around each other... and thus you get wind.  \n\nThank you.

Wind. \n\nHow simple was that?

wind is the result of air pressure, air molecules travel from low to high pressure zones, resulting from air warmed by the sun. The strength of the wind i guess would be dictated by the difference in pressure between two zones, and any obstacles it may have to pass over/through in between...

Wind is the motion of microscopic particles from an area of high pressure to an area of low pressure.  You can feel the particles bumping against your skin, but they are too tiny to see.  Try this:  sometimes you can see light ripples from heat rising off the ground.  This is light hitting a medium (air) and being momentarily refracted from particle motion.  In this case, you can see wind!

The wind is just the observable and measurable manifestation of air molecules being drawn en masse from one place to another by a differential in atmospheric pressure between the two places.  What causes most of these pressure differentiations is (a) earth's rotation creating friction between the lower and upper components of the atmosphere, and (b) temperature gradients in the atmosphere and the oceans caused by the heating action of our star, the Sun.\n\nLet's go fly a kite!

This will create land & sea breezes.\n\nLand (sand) gains & loses heat faster than water due to water's latent heat properties.\n\nDuring the day, the land heats up faster than the water. A low pressure will develop over the land. This means that the air above the ground is warmed & will rise.\n\nSince air pressure will equalize, air from over the sea will move inland to replace the air that was lifted. A convection current starts. This is a sea breeze. (winds are named for the direction they come from.)\n\nThe opposite occurs at night. The land cools faster than the water. Since the water is warmer at night, a low pressure cell forms over the sea.\n\nHigher pressure from over land moves toward the low pressure to equalize. This is called a land breeze b/c it comes from the land.

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 the rotation of the planet (Coriolis effect).\n\nGiven a difference in barometric pressure between two air masses, a wind will arise between the two which tends to flow from the area of high pressure to the area of low pressure until the two air masses are at the same pressure, although these flows will be modified by the Coriolis effect in the extratropics.\n\nWinds can be classified either by their scale, the kinds of forces which cause them (according to the atmospheric equations of motion), or the geographic regions in which they exist. There are global winds, such as the wind belts which exist between the atmospheric circulation cells. There are upper-level winds, such as the 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 breeze. 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 metres and are essentially unpredictable, such as dust devils and microbursts.\n\nWinds can also shape landforms, via a variety of eolian processes.

in localized area's rain may come in any direction.  But in reginal scale, rain generally comes from the west due to coriolis effect & the cold air coming down from higher lattitude.\n\nAlso, when cold & warm air are mixing, cold air catches up the warm air from behind in counter-clockwise rotation, which produces rain / storm.

when you consider that wind is comprised of oxygen, nitrogen, carbon dioxide, and other gases with little to no color the question becomes how could you see wind. sure you can see results of air circulation like moving plants, dust, and papers moving, but you are not seeing air or wind merely the results of it moving. smoke in the air is about the closest you can get to seeing air itself move.

It's due to the jetstream which is located at about 250 mb which is approximately 12km above the surface (give or take).\nAnyway the jet stream does circle the globe (not always continuously) flowing from west to east (in the northern hemisphere).  Our weather systems are steered by the upper level winds associated with the jet stream.  Keep in mind though, the jet stream does have troughs and ridges which causes weather systems to move north or south, but the general flow is from west to east.\n\n-For those who say it's the rotation of the Earth... it is in a way because it's the unequal heating of the earth and the rotation of the earth that creates the jet stream.  But it really is upper level winds which steer weather systems.

WIND \nAir that flows in relation to the earth's surface, generally horizontally. There are four areas of wind that are measured: direction, speed, character (gusts and squalls), and shifts. Surface winds are measured by wind vanes and anemometers, while upper level winds are detected through pilot balloons, rawin, or aircraft reports. \nWhoosh! You know that wind is moving air. But what causes the air to move? It’s the uneven heating of the earth’s atmosphere. \n\nAs the sun warms the earth’s surface, the atmosphere warms too. Some parts of the earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cool air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

air naturally comes from high pressure fronts to low pressure fronts\n\nalso if you look at weather maps those wierd looking squiggly lines \nthe closer together they are the higher wind speed you'll have

the answer is blowing in the wind

because hot air rises and cold air sinks.\n\nit creates pressure changes, which make air particles move rapidly, hence we have wind.

wind is the result of basically a pressure difference.whenever there is a pressure difference between two places the wind blows from the high pressure side to the low pressure side.this pressure difference can be caused due to several reasond...in summers,the land is overheated and so is the air just around it.the air gets hot and start rising.this tends to lower the pressure of that area.then air from some high pressure area takes the place of that low pressure area.in winters over cooling hightens the pressure of the air.which again tends the air to flow,causing mild winds.near a beach,the heating of the land and the water is uneaven and thus causes the sea breeze during the day and land breeze during the night.

This is a mystery and no one really knows. It could be that the rings are relatively recent and the result of the gravitational destruction of a small moon and the debris has not yet totally circumscribed the planet. An even bigger mystery is why an object so cold can have winds of 1200 kms/hour! Where's the energy coming from? What's driving these colossal winds? Jules, Australia.
