How do planetary wind belts affect the climate?
How do planetary wind belts affect the climate?
On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Thus, a wind travelling north from the equator will maintain the velocity acquired at the equator while the Earth under it is moving slower.
Which wind belt has the greatest effect on the climate of New York State?
prevailing westerlies
What causes the curved paths of the planetary winds?
The Coriolis effect describes how Earth’s rotation steers winds and surface ocean currents. The Coriolis effect causes the path of a freely moving object to appear to curve. This is because Earth is rotating beneath the object. So even though the object’s path is straight, it appears to curve.
What does the Coriolis force do to winds?
What is the Coriolis effect? The Earth’s rotation means that we experience an apparent force known as the Coriolis force. This deflects the direction of the wind to the right in the northern hemisphere and to the left in the southern hemisphere.
What are the 3 major wind belts and where are they located?
The global wind belts are the three wind belts or wind patterns that cover the planet: the tropical easterlies (or the trade winds) are found near the equator, the polar easterlies are found at the north and south poles, and the prevailing westerlies are found between the two.
What global wind belt is between 0 and 30 degrees?
Tropical Easterlies
Does the sun affect global wind belts?
Unequal heating of the Earth’s surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles. This belt of air around the equator receives much of the sun’s radiant energy.
Does air pressure affect global wind belts?
Global winds blow in belts encircling the planet. Notice that the locations of these wind belts correlate with the atmospheric circulation cells. Air blowing at the base of the circulation cells, from high pressure to low pressure, creates the global wind belts.
How do air temperatures create global wind belts?
Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
What two factors create the Earth’s major wind belts?
Wind belts are formed due to unequal heating of the earth and the earth’s rotation. The first wind belt in our story, the polar easterlies, lies between 60 and 90 degrees north and south latitude and blows from the poles.
Which wind belt is caused by air returning to the equator at about 0 to 30 degrees latitude?
What do all of Earth’s major wind belts have in common?
What do all of Earth’s major wind belts have in common? Compare surface winds and jet streams. Jet stream only moves in one direction, moves with the rotation of Earth, while surface winds move in two different directions, with and against the Earth’s rotation. You just studied 16 terms!
What are the two main reasons for the wind patterns on Earth explain what winds are created with each factor?
The Earth has consistent wind patterns when looked at from a global scale. Global winds are created by both the spin of the Earth (Coriolis effect) and the differences in temperature between the equator and the polar areas. These winds are often grouped together as trade winds, easterlies, and westerlies.
