1. Choose the incorrect statement:

  1. Anabatic Winds – These Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column.
  2. Katabatic Winds – Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a downslope wind.

B. Only 2

C. Both 1 and 2

D. Neither 1 nor 2

2. Which of the following explains the role of airmasses in macro-climatic changes :

  1. The interaction of cold and warm air masses gives rise to extratropical cyclones and associated rainfalls.
  2. When air mass originates in the coastal areas, it contains more humid content which causes heavy precipitation.

A. Only 1

B. Only 2

C. Both 1 and 2

D. Neither 1 nor 2

Answer: D

Explanation 

  • Anabatic Winds – These Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column.
  • Katabatic Winds – Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a downslope wind.

A. Only 1 and 2

B. Only 2 and 3

C. Only 1 and 3

D. 1, 2 and 3

Answer: D

Explanation

  • The interaction of cold and warm air masses gives rise to extratropical cyclones and associated rainfalls. 
  • When air mass originates in the coastal areas, it contains more humid content which causes heavy precipitation.
  • A hot dry airmass could give rise to devastating droughts as well as wildfires.
  • Convectional Lifting – Vertical distribution of temperature 
  • Orographic Lifting – Air masses lifting over mountains , they change weather conditions and are known as Orographic Lifting .
  • Discuss the concept of air mass and explain its role in macro-climatic changes (UPSC – 2016)

3. Choose the correct statements :

  1. Meandering in Jetstreams depends on temperature contrast .
  2. A meander is called trough if it is towards poles and peak or ridge if it is towards equator.

A. Only 1

B. Only 2

C. Both 1 and 2

D. Neither 1 nor 2

Answer: A

Explanation

  • Meandering in Jetstreams depends on temperature contrast .
  • A meander is called trough if it is towards equator and peak or ridge if it is towards piles.

4. Identify the conditions for formation of Tropical Cyclones:

  1. Large Sea Surface with temperature higher than 27 degree Celsius
  2. Presence of Coriolis force
  3. Existence of conditions of ITCZ

A. Only 1 and 2

B. Only 2 and 3

C. Only 1 and 3

D. 1, 2 and 3

Answer: D

Explanation

  • Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large-scale destruction caused by violent winds, very heavy rainfall and storm surges. 

The conditions favorable for the formation and intensification of tropical storms are: 

  •  Large sea surface with temperature higher than 27° C; 
  •  Presence of the Coriolis force; 
  •  Small variations in the vertical wind speed; 
  •  A pre-existing weak low-pressure area or low-level-cyclonic circulation; 
  •  Upper divergence above the sea level system 
  •  Existence of conditions of ITCZ

Which of the statements given above is/are correct?

A. 1 only

B. 2 only

C. Both 1 and 2

D. Neither 1 nor 2

Answer: B

Explanation

  • The Westerlies are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.  
  • The moist air masses that cause winter rains in North-Western region of India are part of westerlies.
