Question : 11 [SSC LDEO 2011]
Frontal Rain is caused by
a) Winds from sea
b) Convection current
c) Condensation of water evaporated from mountains
d) Cyclonic activity
Answer »Answer: (d)
Frontal rainfall is a type of precipitation that occurs when a warm air mass and a cold air mass meet. Extra-tropical cyclones form as waves along weather fronts before occluding later in their life cycle as cold-core cyclones.
Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low-pressure area).
Question : 12
The jet aircraft fly very easily and smoothly in the lower stratosphere. What could be the appropriate explanation?
- There are no clouds or water vapour in the lower stratosphere.
- There are no vertical winds in the lower stratosphere.
a) 2 only
b) 1 only
c) Neither 1 nor 2
d) Both 1 and 2
Answer »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.
Question : 13
List I | List II |
A. Cloudiness and heavy precipitation unfavourable | 1. Equatorial region |
B. Westerlies throughout the year and mild winters | 2. Mediterranean region |
C. Famous for game parkland type of vegetation | 3. Savanna region |
D. Dry summers, wet winters and orchard farming | 4. West European region |
a) A – 4 ; B – 1 ; C – 3 ; D – 2
b) A – 1 ; B – 4 ; C – 3 ; D – 2
c) A – 4 ; B – 1 ; C – 2 ; D – 3
d) A – 1 ; B – 4 ; C – 2 ; D – 3
Answer »Answer: (d)
Question : 14
Which of the following statements is/are correct?
- Cyclone is a low-pressure system.
- The wind movement is clockwise in the cyclone of the northern hemisphere.
a) 2 only
b) 1 only
c) Neither 1 nor 2
d) Both 1 and 2
Answer »Answer: (b)
Cyclones are moving bodies of air in an enclosed area rotating in the same direction as the earth. The air inside the cyclone moves anticlockwise in the Northern Hemisphere.
Question : 15 [SSC CHSL 2015]
All vital atmospheric processes leading to various climatic and weather conditions take place in the :
a) Troposphere
b) Stratosphere
c) Exosphere
d) Ionosphere
Answer »Answer: (a)
The troposphere, which extends up to a height of 12 km on average from the surface of the earth, is the locale of all the vital atmospheric processes which create the climatic and weather conditions on the earth’s surface.
About half of the mass of air comprising the entire atmosphere is concentrated in this zone. This is the lowermost layer of the atmosphere.
