Tropical cyclones do not form over equator. This is 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.
1 and 2 only
1 and 3 only
2 and 3 only
none
Explanation:
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 equator and not exactly at 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.
