Q121

Consider the following conditions favourable for the formation and intensification of Tropical Storms :

  1. Presence of the Coriolis force

  2. Upper divergence above the sea level system

  3. High variations in the vertical wind speed

Which of the conditions given above is/are correct ?

  1. (a) 1 only
  2. (b) 2 only
  3. (c) 1 and 2Correct answer
  4. (d) 2 and 3

Solution.

Answer: (c) 1 and 2

  1. Coriolis force helps organise rotation, while outflow or divergence aloft supports rising air and low surface pressure.
  2. Strong vertical wind shear disrupts the storm’s vertical structure; weak shear is favourable.
  3. Therefore only 1 and 2 are correct.
