In the South Atlantic and South-Eastern Pacific regions in tropical latitudes, cyclone does not

Explanation

Even though UPSC has given B as correct, the right answer is A. Option C is wrong. Coriolis force is weak only in the region around 0-5 degrees North or South latitudes. Option B is also wrong. ITCZ formation is not essential to the formation of cyclones. Cyclones are formed in regions where ITCZ does not form, for e.g. in North Atlantic. Option D is absurd as absence of land boosts cyclones. Presence of land cuts off moisture from the cyclone. So, the most appropriate answer should be A. For cyclone formation, a sea temperature of at least 26 degree Celsius is needed. In the South-eastern pacific and South Atlantic region cold currents are found. This leads to lower sea temperatures. Hence, cyclones don’t form there.Tikdam: Controversial question
