Question

Which of the following conditions is/are conducive for the formation of tropical cyclones?
1. Large and continuous supply of warm and moist air.
2. Large value of coriolis force.
3. Inflow of air at upper level of atmosphere.
Which of the above statement(s) is/are correct?

• A. Only 1 and 2
• B. Only 1
• C. Only 1 and 3
• D. All of the above

Answer 1

The correct option is A Only 1 and 2

Large and continuous supply of warm and moist air is the most important condition for formation of tropical cyclone. Where coriolis force is zero (like equator), tropical cyclones do not develop. An upper level outflow of air (and not inflow) helps in formation of tropical cyclone.
