The correct answer is option 1, which states that statements 1, 3, and 4 are correct. Let`s analyze each statement to better understand why.
Statement 1: The wind direction is clockwise in the cyclone of the northern hemisphere. This is true. In the northern hemisphere, cyclones rotate in a clockwise direction due to the Coriolis effect, which is caused by the rotation of the Earth.
Statement 2: The planetary wind that blows from northeast to northwest is known as the northeast trade wind. This statement is not mentioned in the options, so it is not considered as part of the correct answer.
Statement 3: The wind direction is counterclockwise in the anticyclone of the southern hemisphere. This is true. Similar to statement 1, anticyclones in the southern hemisphere rotate counterclockwise due to the Coriolis effect.
Statement 4: Both westerlies and trade winds originate from sub-tropical highs. This is true. The westerlies, which are prevailing winds from the west, and the trade winds, which blow from the northeast in the northern hemisphere and the southeast in the southern hemisphere, both originate from areas of high pressure known as sub-tropical highs.
