How earth's rotation affects the wind system?

Answer 1

How Does The Rotation Of The Earth Affects the Wind System?

The wind is deflected or bends to the right in the Northern Hemisphere, and bends to the left in the Southern Hemisphere. There are three major sets of winds in the northern hemisphere: Polar easterlies, Prevailing westerlies , and northeast trade winds. The Southern Hemisphere have the same major sets of winds. The northeast and southeast trade winds converge in areas that lie between 30°N to 30°S of the equator. The area where the trade winds converge together is called the intertropical convergence zone (ITCZ). Thunderstorms and rains occur in the ITCZ because of the difference in temperature and pressure.

In the Philippines, cold winds from Siberia cool the air from December to February. In southern china and Mongolia, the weather becomes very cold that a high pressure area develops. Over the northern Pacific Ocean, Aleutian islands, and Australia, a low pressure area develops at same time the high pressure area in Siberia and Mongolia develops, the cold air from high pressure area moves toward the low pressure area.

The Coriolis effect diverts the cold air's direction and turns it to the right towards the philppines from the northeast direction. The cold moving air that passes over the Philippines is called northeast monsoon. The northeast monsoon is drawn towards the low pressure area over Australia.

The large air mass (Northeast monsoon), which starts in Siberia, chills in the Philippines from December to January. It eventually goes down to Australia. The wind system is known amihan by Filipinos.

From March to may, the Philippines temperature is at its highest, warm air rises over the country as a result. Habagat (southeast monsoon) visits the country from June to November. The southwest monsoon brings much rain starting the rice planting season.

Answer 2

So what does cause the wind to blow in a given direction? While the Earth's rotation does play a role, it is a somewhat indirect one. The primary factor that affects the formation of winds is differences in atmospheric pressure.

Nevertheless, you are correct in that the Earth's rotation does play some role in the formation of winds, and therefore has an indirect effect on the difference in east-to-west flight times. The rotation of the Earth creates what is known as the Coriolis force. since the Earth is rotating beneath the wind, the path it follows becomes a curve. In the Northern Hemisphere, the Earth rotates counterclockwise so the wind is deflected to the right. The Southern Hemisphere rotates clockwise deflecting the wind to the left. Regardless, the Coriolis effect only influences the direction of the wind, not its speed. So you can see that wind cannot be explained by something as simplistic as the rotation of the Earth. It is instead a complex fluid dynamics problem that involves the Earth's rotation, imbalances in the heating of the atmosphere caused by the Sun, and the absorption and radiation of heat by large bodies of water.

Answer 3

wind is created by the uneven heating and cooling of the earth's surface. earth's rotation has nothing to do with it.

Actually because earth rotates, the winds don't blow in a straight line. If earth did not rotate they would go from north to south and south to north in a straight line.

Answer 4

YES !

It's the major factor.
