Wind is triggered in the beginning by what force?

Answer 1

This is a very good question. What you need to understand is that a balance is established as the wind moves. What are the major forces at work here? Well first is solar radiation, then there is a rotating earth in an orbit about the sun and inclined to its orbit. This generates unequal heating on the earth's surface and in its atmosphere. Unequal heating causes pressure differences which initiate the movement of the atmosphere which we call the wind. The Coriolis acceleration begins to act on the moving wind causing it to move to the right in the northern hemisphere and to the left in the southern hemisphere. There is also a force caused by surface friction which tends to slow the wind down. When there is a perfect balance the wind is said to be in geostrophic balance. In this case the wind flows parallel to the isobars (lines of equal pressure). But since this never occurs perfectly the winds tend to cross the isobars rather than run parallel to them. Around a low pressure center the pressure gradient acts inward toward the center of the low. The Coriolis acceleration acts to the right of the flow or in the opposite direction of the pressure gradient. The friction acts along the direction of motion. The result is wind that tends to spiral into the low. An opposite situation is established with an anticyclone. Hope this helps a little. I could do it much better on a blackboard.

Answer 2

What is wind?
Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. Two factors are necessary to specify wind: speed and direction.

What causes the wind to blow?
As 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 cold air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

Answer 3

The Coriolis force

Answer 4

An air mass travelling from a high pressure area to an area of lower pressure.

Answer 5

Air pressure changes. Which can be caused by any number of factors including humidity, temperature and natural terrain.

Answer 6

To put it simply, differences in High and Low pressure. High pressure areas flow to Low pressure areas.

Answer 7

sun heats the earth...it heats the land more than the sea.....hot air over the land rises.....cool air from the sea rushes in to replace the air that has risen..
