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 2
  4. D. 2 and 3

Correct Answer: C. 1 and 2

Explanation

Tropical storms require the presence of the Coriolis force and upper-level divergence. High variations in vertical wind speed (strong wind shear) disrupt storm formation and are thus unfavourable.
