where does wind come from? and i mean weather wise smart ppl?

Answer 1

momentom of the earth moving i would imagine

Answer 2

Good question Paul. Here is a short scientific answer to your question. Wind is simply the movement of air. That movement is governed by what are called the Equations of Motion which are derivatives of the x, y, and z components of the velocity vector of the air at any point. The x, y, and z components are u, v, and w. So basically we have three equations like du/dt = sum of the forces/ unit mass (acceleration) acting on the air. These forces are the pressure gradient caused by differential heating of the earth's surface, friction causing the air to be slowed down as it moves from high to low pressure due to the pressure gradient force. And finally, we have a Coriolis Acceleration which causes the air to move to the right of its direction of movement in the northern hemisphere.

Because these three equations and others are expressed as time derivatives they may be numerically integrated in order to produce forecast of these variables (for example u, v, and w the wind velocities in the x, y, and z directions) at a specified future time.

Hope this helps a little.

Answer 3

The sun delivers vast amounts of solar energy to the earth every day but more at the equator than at the poles and the poles slant toward the sun and away from the sun as the seasons progress. Wind serves the basic purpose or distributing excess energy away from the equator toward the poles. If the earth did not spin, hot lighter air would flow directly north and colder denser air would return from the poles to the equator. Because the earth does spin the process is also influenced by Coriolis forces causing air masses to spin (especially hurricanes and tornadoes) during their progress. The jet stream at higher elevations shifts with the seasons and helps guide the moving air masses. Of course strong local wind gusts may result at the forward edge of a thunderstorm as falling rain entrains considerable air pushing it out of the way as it reaches the ground (just before the cloudburst).

Answer 4

Wind comes from different pressure regions in the earths atmosphere - not pressure due to altitude, pressure caused by heating of the air by radiation from the sun. You may recall seeing a weather map with lines/contours drawn over it. These are known as 'Isobars' and are drawn because they represent areas of constant pressure - hence the latin term 'Iso', and the scientific unit of pressure 'Bar' - Isobar. It is a law of physics that a gas/liquid will flow from a high pressure to a low pressure - hence why a ballon will fly around if the air is let out of it.

So if we equate this to weather, a region on the planet with a high pressure region say 1020mB (Millibars) and an region nearby with low pressure; say 998mB (These are just hypothetical figures) - the air will flow from high to low, so the region experiencing low pressure will have wind flowing from the direction of the high pressure region. The greater the pressure difference, and the closer the high/low regions are, the stronger the wind will be.

Hope this helps

Answer 5

I did this in college yesterday... it's sort of, you know how heat rises, and cool air sinks? Well say you're on a cliff, during the day the cliff is warmer than the sea, so the heat will rise from the cliff and go up over the sea, then as the heat cools down over the sea it drops, and cold air is always attracted to hot air, so the farther the air travels until it cools, the faster it will go - thus wind.
Does that make sense? There were lots of diagrams when we were studying it and I can't draw any on here! Hope its ok!

Answer 6

For the most part, winds and air currents are created as the earth's atmosphere tries to regulate the temperature, air pressure and humidity between different parts of the globe.

Warmer air for instance is at a higher pressure but lower density than cooler air. So air from warmer areas of the earth tends to travel towards to cooler areas. Cooler air is at a lower pressure but higher density, so weather systems associated with cooler air is always more turbulent and unsettled than those associated with warmer air.

Large global air currents circulate air between warm and cooler areas, whilst local differences in temperatures and air pressure results in micro-climates. These localised climates can be affected by sea currents and temperature, land mass and type, etc.

The rotation of the earth also has an impact in the direction of winds, as the resistance between the air and the earth's surface cause little turbulences and push/pull pockets of air with the movement of the earth. Landscape features such as hills/mountains/valleys also change and affect direction and strength of winds.

Answer 7

Air in motion is called the wind.Due to diffential heating of the earth's surface and sea surfaces by the solar radiation,low pressure and high pressure areas are created within land and sea areas or between land areas and sea areas.Because of this, pressure gradients are formed which force air to move from high pressure area to low pressure area causing the wind flow.

Answer 8

The Earth and air are joined together. When the planet rotates faster than the wind can catch up, it causes drag and makes things blow

Answer 9

Its all those wind farms they keep putting everywhere.

Waste of money if you ask me.

Answer 10

wind is mixture of moisture, o, h, n, and many more gases. havier the atmosphere, faster the wind?

Answer 11

Dont know where it comes from, but tell me where does it go.

ps, its outside at the moment
