Question : 46
Westerlies in southern hemisphere are stronger and persistent than in northern hemisphere. Why?
- 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
Answer »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.

Question : 49 [SSC CML 2006]
What is a ‘tornado’?
a) A very low pressure centre
b) A very high pressure centre
c) A planetary wind
d) A very high ocean wave
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.
Question : 50 [SSC SIG 2006]
Blizzards are characteristic features of—
a) tropical region
b) equatorial region
c) temperate region
d) Antarctic region
Answer »Answer: (d)
Blizzards are characterized by low temperatures (usually below 20 degrees Fahrenheit) and accompanied by winds that are at least 35 mph or greater.
Blizzards also have sufficient falling and/or blowing snow that reduces visibility to 1/4 mile or less at least three hours and is the main feature of the Antarctic region.
