Question

Tropical cyclones do not form over the equator because -
1. Equator is a zone of wind convergence.
2. The temperature over equator is too high.
3. There are no fronts over equator.
Select the correct answer using the codes given below.

• A. A) 1 and 2 only
• B. B) 1 and 3 only
• C. C) 2 and 3 only
• D. D) None

Answer 1

The correct option is D D) None

90. D

Tropical cyclone does not form over the equator because the Coriolis force is zero at the equator. Even though equator is a zone of wind convergence, it has nothing to do with tropical cyclone as such. Temperature is highest north and south of the equator and not exactly at the equator. Fronts are required for formation of temperate cyclone and not tropical ones. So even though statement 3 is correct it is not a reason.
