How does the wind change direction?

Answer 1

its all to do with the earths spherical motions and also when im on the tee!!!!!

Answer 2

wind is all about atmospheric pressure. The surface of the earth is covered with low pressure and high pressure areas. Air moves from high pressure areas to lower pressure areas.

You can imagine this the same as water. Water flows to lower areas. Air will "fill up" the low pressure area and create a higher pressure area, this high pressure are will then look for other areas to flow into. This constantly occurs throughout the world creating pockets of low and high pressure areas.

So the movement from one area to another creates wind also while in a high or lower pressure zone the air still moves. Air in the zones will spin counter clock wise or clock wise depending if it is a high pressure zone or a low pressure zone.

So there are two factors that cause the wind to change direction - one is the current air pressure zone over a certain area and the direction that zone in moving (either "filling up" or "draining").

However there are things such as trade winds and pervailing winds that are cause by other factors, but that will only complicate things - above is a simple idea about normal winds you feel day to day.

Answer 3

The easiest way to describe it is to show you. The link below will lead you to an Atlantic pressure chart. As a weather system moves across the face of the planet it also rotates; anticlockwise for a low pressure system (cyclone), clockwise for a high pressure system (anticyclone). The distance between the lines also indicated the wind speed : the tighter the isobars are bunched, the higher the wind speed.

As the weather system moves, the associated winds will alter their direction depending where the centre of the system is relative to your position.

Answer 4

Wind is a movement of air, primarily due to pressure gradients (this difference in air pressure between two areas). At surface level, winds blow from areas of high pressure to areas of low pressure.

Differences in air pressure are mainly caused by uneven heating of the earth's surface - maybe due to different seasons, different land types (which have different heat capacities) or cloud cover. Air masses also have different air pressures - for example polar air masses are usually high pressure as they are cold and dense - and at the boundaries of these air masses (fronts) there is a very large pressure gradient and, hence, strong winds.

Winds change direction as the areas of highest and lowest pressure move around, and are effected by the coriolis effect - when the spin of the earth deflects winds.

Answer 5

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).

Answer 6

It depends on atmospheric pressure. Pressure depends upon the temperature at a particular place. so when temperature changes the wind changes its direction.

Answer 7

wind change direction from the upper side off the atmosphere and
the lower side do to hot and cold air, and that's one fact .

Answer 8

in addition to the local influence mainly Because of Coriolis Force.

Answer 9

It all has to do w/ pressure gradients at different elevations and variations of coriolis force at different latitudes.

Answer 10

Do you stutter? you just asked this quetion 2 mins ago.

Answer 11

Depends which way you point your ar se.
