Official: SFG / RLG All Tests Discussions in one place
Hello All,
The Group usage here is a little cumbersome, so I am creating this thread to make sure that all questions with doubts stay in one place. Can someone push all the doubts and queries here? I will make this an announcement?
-Faceless, Anonymous "root"
Test 28, Q 41. City with population 10 lakh and above and not 5 lakh and above
The statement is asking recommendation under 6th NPC report - (National Police Commission in the 6th report, a system of Police Commissionerate should be introduced in cities with a population of five lakhs and above). Please verify https://niti.gov.in/writereaddata/files/document_publication/Strengthening-Police-Force.pdf
Doubts:
Q47. Aren't tropical cyclones more destructive than extra tropical cyclones?! (Though the word used is 'always'). Were there any incidents recorded where extra tropical cyclones were more destructive than tropical cyclones?
Q.42. Strength of westerlies do increase in sothern hemesphere because of vast ocean. Thats why they r called roaring forties, and shrieking sixties.
Tropical Cyclones are always more destructive in nature in comparison to Extra - Tropical Cyclones (theoretically), unless we include subjective contexts. Then the question becomes subjective.
Lighthouse,Bishnoi_Warrior@Thinker Ques no 5 stmt 1 - can it be right? word "only" is used, earth can be heated up from insolation too.

Q. 47) Braer Storm of 1993 accelerated to nearly 150 km/h (93 mph).
The Saffir–Simpson hurricane wind scale (SSHWS), classifies hurricanes – Western Hemisphere tropical cyclones – that exceed the intensities of tropical depressions and tropical storms – into five categories distinguished by the intensities of their sustained winds. To be classified as a hurricane, a tropical cyclone must have one-minute maximum sustained winds of at least 74 mph (33 m/s; 64 km; 119 km/h) (Category 1).
Also, there is the case of Bombogenesis. Bombogenesis, a popular term used by meteorologists, occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours. This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters. The formation of this rapidly strengthening weather system is a process called bombogenesis, which creates what is known as a bomb cyclone.
So Always in the statement makes the statement incorrect.
Q.42) The strength of Westerlies in the Southern hemisphere decreases as we move polewards from the subtropics. (From the Subtropics to Poleward). The strongest westerlies blow through Roaring forties.https://www.nationalgeographic.org/encyclopedia/wind/

The question is previous year verbatim question of 2012. The statement is asking about the heating of the atmosphere (and not earth). Further, upward heating is caused only by radiation emitted from the earth's surface which are long wave radiations and are absorbed by the atmosphere thereby getting heated.

Q.42) The strength of westerlies does increase in the southern hemisphere because of the vast ocean. This is what is mentioned in the statement of the question- The strength of Westerlies in the Southern hemisphere increases as we move polewards from the subtropics. (From the Subtropics to Poleward).
Sir, but in the answer given to Q42 is given as b) option
Then it should have been C) (i.e 2 and 3 only)

A typo error. Sorry for the mistake. please refer to it again.
please explain question no. 32 in Test 29
When a cold front passes over an area then
1.Temperature decreases
2. Relative humidity increases
3.Sky becomes clear

please tell me the specific doubt.
@Thinker . Okay sir. Thanks for the clarification. Will refer the updated key when it gets uploaded. :)

I have updated the explanation itself.
The strength of Westerlies in the Southern hemisphere decreases as we move polewards from the subtropics. (From the Subtropics to Poleward). The strongest westerlies blow through Roaring forties.https://www.nationalgeographic.org/encyclopedia/wind/
the strongest westerlies blow through the “Roaring Forties,” a wind zone between 40 and 50 degrees latitude in the Southern Hemisphere.
In all standard books we only had mention about the westerlies in southern hemesphere as strong winds, so I assumed that its intensity would increase polewards.
Thanks for the link.
