Which of the following factors is least responsible for the formation of a tropical cyclone over the Bay of Bengal?
Answer
High atmospheric pressure
The correct answer is High atmospheric pressure — Hence high atmospheric pressure is the least responsible factor.
Step-by-step solution
- Identify the three essential factors for cyclone formation: warm sea surface temperature, Coriolis force, and low vertical wind shear.
- Recognise that high atmospheric pressure promotes stable, dry conditions and is opposite to the low‑pressure environment needed for cyclones.
- Hence high atmospheric pressure is the least responsible factor.
Common mistake: Assuming high pressure aids cyclone development
Concept tested: Cyclone formation factors
