What Causes Global Winds To Form

These global wind systems in turn drive the oceans surface currents. To the left in the southern hemisphere so that the wind flows mostly around the high and low pressure areas.

Local winds are winds that are produced by changes in the air pressure when the air pressure changes a wind forms.

What causes global winds to form. The continual heating and rise of air at the equator create low pressure there which causes air to move wind towards the equator to take the place of the air that rises. On a rotating planet air will also be deflected by the coriolis effect except exactly on the equator. Winds are made by temperature changes caused by the heating of earth s surface.

The dominant winds are the trends in direction of wind with the highest speed over a particular point on the earth s surface. When a difference in atmospheric pressure exists air moves from the higher to the lower pressure area resulting in winds of various speeds. Global winds blow in the same directions all the time and are related to the unequal heating of earth by the sun that is that more solar radiation strikes the equator than the polar regions and the rotation of the earth called the coriolis effect.

Because earth rotates winds appear to be moving east in the coriolis effect. Ships that sail in these zones can move very quickly because of the strong winds. Global winds earth s orbit around the sun and its rotation on a tilted axis causes some parts of earth to receive more solar radiation than others.

Wind is caused by differences in the atmospheric pressure. The polar easterlies form when cool air from the poles sinks and begins to move toward the equator as the air flows away from the poles the coriolis effect caused by earth s rotation causes the winds to curve to the west. Wind is caused by air flowing from high pressure to low pressure.

If earth did not rotate winds would move from the equator to their respective poles. Since the earth is rotating however the air does not flow directly from high to low pressure but it is deflected to the right in the northern hemisphere. For example the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere.

This uneven heating produces global circulation patterns. Large global wind systems are created by the uneven heating of the earth s surface. To understand how global winds form and drive the major ocean currents you need to know that wind is the basically the movement of air from an area of high pressure to an area of low pressure.

Global winds are a system of wind patterns distributing warm air unevenly across earth. The causes of the global wind patterns will be described in detail later when we look at the atmosphere. Citation needed dubious discuss a region s prevailing and dominant winds are the result of global patterns of movement in the earth s.

The prevailing wind in a region of the earth s surface is a surface wind that blows predominantly from a particular direction. On the other hand sinking air creates high pressure at the surface where it descends.
