Question

Explain in the following terms:
a. Polar winds
b. The westerlies
c. The Coriolis force

Answer 1

Hint: The wind is a large-scale flow of gas. On the surface of the earth, the wind is made up of large amounts of air movement. In outer space, solar wind is the movement of gas or charged particles from the sun in space, while planetary wind is the gas that releases light chemical elements from the planet’s atmosphere into space.

Complete answer:
(a) Polar winds: These winds blow between latitudes 60 degrees and 65 degrees. These polar winds are mostly in the east. These high latitudes are mostly covered in ice, so cold, dry arctic winds flow away. There are strong polar fronts near the poles. In arctic regions, the speed and direction of seasonal winds depend on local conditions.

(b) Westerlies: Westerlies countries dominate in both hemispheres between 35 and 60 degrees or 65 degrees north and south. Westerlies blow from horsepower to subpolar low-pressure belts in every hemisphere.

(c) Coriolis Force: The Coriolis force generated by the earth's rotation affects any moving object, whether it be ocean currents or a bullet fired from a gun. The Coriolis force is zero at the equator and maximum at the poles. In the northern hemisphere, the Coriolis force acts to the right of the wind direction and in the southern hemisphere, the Coriolis force acts on the left.

Note:
The trade winds or easterlies are winds that always exist from east to west that flow in the equatorial region of the earth. Trade winds blow mainly from the northeastern northern hemisphere and from the southeast of the southern hemisphere and increase in winter and when the Arctic oscillations are in their warm phase.
