Which one of the following conditions does not favour the formation of a tropical cyclone?

  1. Temperature above $27°$C

  2. Significant vertical wind difference

  3. High humidity levels

  4. Divergence in the upper atmosphere
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical cyclones require low vertical wind shear to develop. High vertical wind shear disrupts the storm's structure and prevents the vertical alignment necessary for intensification.
