why is there wind?

Question

how does the wind accour- and why sometims its fast( hard) and sometimes its cold or warm

Answer 1

Ultimately because of differences in heating by the sun that get air moving. The differences can be due to water vs land, dark land vs planted crops, desert vs trees, etc. When air is heated it rises and that pulls other air after it which has to move horizonally near the earth or up hills. Once air is moving, you can get cold winds because, among other reasons, moving air piles up behind mountains and the cold stuff poured over the top and sinking down the other side makes a wind.
Most winds come from more complex movements between low and high pressure centers, but those are caused by heating the air.

Answer 2

Air in motion is called wind.When there is a pressure gradient(pressure difference) between two places,the air is pushed from the high pressure area to the low pressure area leading to wind flow.So, as long as air is there,(and a pressure gradient to influence it)wind will also be there.
Wind is seldom steady at a particular place.There is a rapid increase(gust) and decrease(lull) in speed due to turbulence in the atmosphere which in turn depends upon the convection over a place.These cause small eddy currents leading to variations in the speed.
Moving air normally carries the temperature of the place of origin,getting modified on its way owing to the different surfaces(land and sea) over which it is flowing and therefore the wind arrives at a place as a warm or cold current according to the track it has followed.

Answer 3

wind occurs naturally when the earth spins. back before earth was a planet the held living things the moon was closer and earth span much faster. these solar winds were in spped of 100 mph
now we dont get winds because of earths spinning but mostly because of the jet stream and high and low pressure.
naturally air blows from a high pressure to a low pressure
also wind can feel warm or cold. this has many factors.

warm wind
normally blows from the south to the north

cold wind
blows on a cold day -wind chill-
blows from the north to the south
blows from the sea to the land

Answer 4

There is high and low air pressure.
Air flows from high to low pressure areas- that flow is wind.
If the air in the high pressure area is hot then the wind will be hot.
If the air in the high pressure area is cold than the wind will be cold.
If the high pressure isn't very much different to the pressure in the low area the wind will be slow.
If the high pressure is very much different to the low pressure area then the wind will be faster ( harder).

Answer 5

you want sustained winds above eighty mph to get injury. if the home is equipped to well-liked wind injury standards, you,ll be o.ok. my living house in batavia is 40 years previous. that is in basic terms superb. we did lose a maple tree to the wind.

Answer 6

mike1942 has it basically right. it is due to the UNEQUAL heating of the earths surface
