Question 31. Consider the following surface winds:

Doldrums

Trade winds

Westerlies

Polar winds

Which one among the following is the idealized global pattern of these winds from the Equator to the Pole?

1-3-2-4
1-2-3-4
3-1-2-4
2-1-4-3

Discuss Question

Answer: Option B. -> 1-2-3-4
Answer: (b)
Doldrums are a low-pressure area around the equator after which come the trade wind whose expanse is from tropic of cancer to tropic of Capricorn.
They move in the North-East direction in the Northern hemisphere and North-East in the Southern hemisphere.
They are followed by westerlies that prevail in mid-latitude between 30 and 60 degrees latitude. As the name suggests polar winds are closer to the poles.

30° – 40° North and South
20° – 30° North and South
50° – 60° North and South
40° – 50° North and South

Discuss Question

Answer: Option A. -> 30° – 40° North and South
Answer: (a) Two regions, found at latitude 30°-35° north and 35°-30° south of the equator, where there is steady movement of air is known as horse latitudes.
