how is air flow generated in earth?

Question

Want to know whether differences in air pressure has anything to do with flow

Answer 1

In general wind blows from high pressure to low. Along the shore you get sea and land breezes depending on the time of day due to air over the hoter place rising and the air rushing in to replace it.There are also major wind belts around the world.

Answer 2

diferences in pressure have EVERYTHING to do with the flow.
the sun heats the air and causes it to expand. this generates an area of high pressure. high pressure areas will try to move air to nearby low pressure areas. That's why low-pressure areas usually have storms and rain. the clouds all want to move to places of lower pressure. there is an average easternly directed wind through out most of the earth. some people will say it's due to the earth's rotation, but it's not. it's due to the sun's motion through the sky and the way it heats the air. in the day, the pressure is higher than in the night, so air is always fleeing the sun and heading toward the night side of the planet. because the sun is movine east-to-west, the air moves more east, because that is where the sun is leaving.

Answer 3

Major reasons for the flow of air from one place to another are: 1.temperature received from sun, 2.prevented from the cloud es, 3. loss of temperature by rain, 4. storms and cyclones, water currents and 5. presence of deserts. The radiation received from the sun increases the temperature and air becomes lighter and moves up and up. thereby causing a vacuum there which is to be filled by movement of some air from the neighbouring area -a cool area with more velocity. Then the pressure in the area is equated.

Answer 4

Yes it is the common factor. Difference in atmospheric temperature creates pressure differences that makes air flow from High pressure areas to low pressure areas.

Answer 5

differences in air pressure are a big fact, but you can count on coriolis effect (movemet derivated from the rotation of earth) to get the direction of winds also, such as the alisios from the north atlantic ocean

Answer 6

That's the main reason for wind blowing. the other less publicized reason is that some places on earth just suck! (Plain and simple, but not politically correct.)

Answer 7

One way was demonstrated by Al Qeida last year. They all faced New Orleans and blew!
