Multiple choice

Consider the following statements:

  1. The pattern of planetary winds is modified by the centres of high pressure and low pressure.
  2. In the Northern Hemisphere, winds blow in clockwise direction around a low pressure centre and anticlockwise around a high pressure centre.
  3. Monsoon winds are characterised by seasonal reversal of wind speed.

Which of the above statements is/are incorrect?

  1. Only 1 and 2

  2. Only 2

  3. Only 2 and 3

  4. None of these

C Correct answer
Explanation

Statement 1 is correct: Pattern of winds is always a manifestation of pressure-temperature dynamics. The pattern of planetary winds is modified by the centres of high pressure and low pressure. Statement 2 is incorrect: Winds blow in anticlockwise direction around a low pressure centre (i.e. cyclone) and in clockwise direction around a high pressure centre (i.e. anti-cyclone). Statement 3 is incorrect: Wind speed is not the criterion for classification of monsoon winds. Monsoon winds are rather, characterised by seasonal reversal of wind direction.
