उत्तर
The three chief types of winds are Trade winds, Westerlies, and polar winds.
Trade winds: blow along the tropical belt from sub-tropical High to equatorial low-pressure belts. The name trade is given due to the last time when trade ships were sailed according to the direction of these winds.
Westerlies: are the winds blowing from the western direction. These are south-westerly in northern and north-westerly in the southern hemispheres.
The Polar: winds are icy cool winds blowing from poles towards Circum polar low-pressure belts, which are also known as Blizzards.
