Q: 26 (NDA-I/2018)
Consider the following statements about Roaring Forties :
1. They are strong Westerly winds found in the oceans of Southern Hemisphere.
2. The strong east to west air cuirents are caused by the combination of air being displaced from the Equator towards the South Pole and the earth’s rotation and abundance of landmasses to serve as wind breaks.
Which of the statements given above is/are correct ?

{'strong westerly winds': [0, 0, 0, 2], 'roaring forties': [0, 1, 0, 0], 'wind breaks': [0, 0, 0, 2], 'west air cuirents': [0, 0, 0, 1], 'strong east': [0, 0, 0, 2], 'southern hemisphere': [0, 0, 2, 2], 'equator': [10, 0, 6, 7], 'landmasses': [0, 0, 0, 1], 'oceans': [8, 1, 8, 19], 'south pole': [1, 0, 0, 0], 'air': [1, 0, 0, 0], 'earth': [0, 1, 1, 1]}

The correct answer is option 1, which states that only statement 1 is correct. Let`s analyze each statement:

Statement 1: They are strong Westerly winds found in the oceans of Southern Hemisphere.

This statement is correct. The Roaring Forties are strong, uninterrupted westerly winds found in the Southern Hemisphere between the latitudes of 40 and 50 degrees. These winds are characterized by their strength and consistency, making them an important factor in global weather patterns.

Statement 2: The strong east to west air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth`s rotation and abundance of landmasses to serve as windbreaks.

This statement is incorrect. The Roaring Forties are not caused by the displacement of air from the Equator towards the South Pole. They are primarily influenced by the Earth`s rotation and the latitudinal temperature differences between the Southern Ocean and the landmasses in the Southern Hemisphere.

In summary, statement 1 is correct as the Roaring Forties are indeed strong Westerly winds found in the oceans of the Southern Hemisphere. However, statement 2 is incorrect as it does not accurately describe the cause of the Roaring Forties.
