Question 342. The jet aircraft fly very easily and smoothly in the lower stratosphere. What could be the appropriate explanation?
Which of the statements given above is/are correct in this context?
- There are no clouds or water vapour in the lower stratosphere.
- There are no vertical winds in the lower stratosphere.
Which of the statements given above is/are correct in this context?
Answer: Option A. -> 2 only
Answer: (a)
The idea is to optimize fuel burn reason is the low air density that reduces parasitic drag on the airframe. It also allows them to stay above any hard weather (extreme turbulence).
Airflow in the stratosphere is much lesser turbulent than in the troposphere and this is the reason that jet aircraft like to cruise at stratospheric altitudes for, the flight is less “bumpy.” So statement 2 is correct. The majority of clouds form in the Earth’s troposphere, but there are occasions where clouds in the stratosphere and mesosphere are formed and have been observed.
Statement 1 which says that there are no clouds or water vapour in the lower stratosphere, is not a correct statement, to the extent that it does not explain the flight of jets in the lower stratosphere.

Answer: Option D. -> Cumulonimbus, cumulus, stratus, cirrus
Answer: (d)
Answer: (d)
Answer: Option B. -> Ivory Coast
Answer: (b)
Answer: (b)
Answer: Option C. -> The annual rainfall ranges from 1500 mm to 2000 mm
Answer: (c)
Option (c) is incorrect.
The annual rainfall ranges from 400-600 mm. not 1500-2000 mm.
Answer: (c)
Option (c) is incorrect.
The annual rainfall ranges from 400-600 mm. not 1500-2000 mm.
Answer: Option D. -> Magnetism
Answer: (d)

Answer: (d)
Magnetism is not related with wind direction.
Answer: Option C. -> I, II, III and IV
Answer: (c)
EL Nino, unusual warming of surface ocean waters in the eastern tropical Pacific is part of southern oscillation.
Scientists do not know exactly how El Nino forms. It is said that El Nino may have contributed to the 1993 Mississippi and 1995 California floods. The average period length of EL Nino is 5 years.
