what makes wind?

Question

curious.

Answer 1

Wind is caused by a difference in air pressure (sometimes referred to as Pressure Gradient Force).

Think of what happens if you take a bottle that is empty and put it in the water, then open the lid. The water rushes right in. Nature strives to create equilibrium. The same thing happens with wind. If there is a low-pressure zone, the wind blows more air towards it to equalize the pressure. This is why low-pressure systems create storms and hurricanes.

Answer 2

The air pressure is different in different places. Nature wants to even out any change in pressure, causing air to flow from areas with higher pressure towards areas with lower pressure. This airflow is wind.

(The air pressure not being the same all over the world has to do with the fact that the sun heats the earth unevenly.)

Nothing is ever as simple as you would think. The air flow from higher towards lower pressure is complicated by the rotation of the earth, and other factors as well. But the fact remains - if there were no pressure differences, there would be no wind.

Answer 3

Imagine two adjacent parcels of land. One is well-lit by the sun, the other is in the shade of a cloud. The well-lit patch will heat up to a higher temperature and will heat up the air above it. The warm air will start floating up (physicists call this convection) and will be replaced by cooler air flowing in from the shady patch. Now imagine yourself standing on the border of two patches. What will this air movement feel like? Wind, perhaps?

Answer 4

Wind is nothing but an atmospheric pressure which moves from the high pressure zone to the low pressure zone, as formed by the heat of the sun making the air thin of that zone. It moves in the shape of wind to fill up the gap to equalize the atmospheric pressure.

Answer 5

Wind is created as air moves from an area of high pressure to an area of lower pressure. Differences in air pressure are created because places around the world have different temperatures. Cold places typically experience high pressure, though this is not always so and warm places typically experience low pressure.

Answer 6

Winds are produced by differences in atmospheric pressure, which are primarily attributable to differences in temperature. Variations in the distribution of pressure and temperature are caused largely by unequal distribution of heat from the sun, together with differences in the thermal properties of land and ocean surfaces.When the temperatures of adjacent regions become unequal, the warmer air tends to rise and flow over the colder, heavier air. Winds initiated in this way are usually greatly modified by the earth's rotation.

Answer 7

heat... As air heats up it will expand and their fore become lighter. The heated air will then flow up causeing the cooler air arount to come in and fill the void... This is how cold winds happen.

If the air is heated quickly then it will flow up and also out... pushing away the cooler air... this is a warm wind.

Basicly it is all heat... there is some humidity effect. and those have the same results

Answer 8

Wind is caused by the uneven heating and cooling of the earth's surface. The heat rises and the cool sinks, and they have to get out of each others' way. This causes convection currents (wind) that vary in strength.

Answer 9

Wind is the displacement of air- the gases in the atmosphere. When it gets hot, air expands and needs somewhere to go. When it's cold, air takes up less space and thus there is more free room in which other gases can occupy.

Answer 10

Wind is caused by the flow of dense cold air to fill up the space emptied by light warm air. Essentially, it is caused due to differences in temperature due to the Sun's radiation.
