Consider the following statements about Roaring Forties: 1) There are strong Westerly winds found in the oceans of the Southern Hemisphere. 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. Which of the statements given above is/are correct?

Explanation:
The Roaring Forties are strong westerly winds active in the southern hemisphere. They are found generally between the latitudes of 40°S and 65°S. They are west to east air currents (and not east to west) which are caused by the combination of air displaced from the equator towards the South Pole. Hence, statement 2 is NOT correct. Further, few landmasses serve as the windbreak for the formation of these roaring forties. Westerlies blow from the subtropical high pressure belt to the subpolar low pressure belts. They constantly blow from the west and hence called Westerlies. They blow from south-west to north-east in the northern hemisphere and north-west to south-east in the southern hemisphere. They are called Roaring forties because the southern hemisphere lacks landmass between 40-65°S latitudes to break the flow of the Westerlies
