The following question based on Atmosphere & Climatology topic of indian geography mcq
- Southern hemisphere has less landmass as compared to northern hemisphere.
- Coriolis force is higher in southern hemisphere as compared to northern hemisphere.
(a) 2 only
(b) 1 only
(c) Neither 1 nor 2
(d) Both 1 and 2
The correct answers to the above question in:
Answer: (b)
The higher speed and greater persistence of the westerlies in the Southern Hemisphere are caused by the difference in the atmospheric pressure patterns as well as its variation from that of the Northern hemisphere.
The landmass in the southern hemisphere is comparatively less and average annual pressure decreases much more rapidly on the poleward side of the high-pressure belt. Statement 1 is correct.
As far as Coriolis force is concerned, it is strongest in the polar regions and zeroes at the equator. At the intermediate levels, it varies directly as the sine of the latitude.

Answer »Answer: (a)
A tornado is a closed low-pressure circulation that is marked by a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
Low-pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.
