Q31
Under Koeppen's climatic classification of India, which letter code designates the Coromandel coast featuring a distinct summer dry season?
Aw
As
Cwg
Amw
Explanation
The 'As' letter code denotes a tropical climate with a dry summer season, uniquely applicable to the Coromandel coast of Tamil Nadu which receives winter rainfall.
Q32
Which region of India receives minimal rainfall from the winter-dominant Western Disturbances?
Punjab Plains
Southern Peninsula
Western Uttar Pradesh
Kashmir Valley
Explanation
Western Disturbances affect northwestern and northern India (Punjab, Haryana, Jammu & Kashmir) during winter, leaving Southern India completely unaffected.
Q33
Which of the following mountain ranges acts as a barrier to the Bay of Bengal branch of the monsoon, forcing it to cause exceptionally heavy rain in Meghalaya?
Zanskar Range
Garo, Khasi, and Jaintia Hills
Vindhyan Range
Satpura Range
Explanation
The Garo, Khasi, and Jaintia Hills in Meghalaya intercept the Bay of Bengal branch of the southwest monsoon, funneling the winds and causing extreme orographic precipitation.
Q34
What is the primary thermodynamic reason why air masses warming up over the Thar Desert do not cause significant rainfall during the summer monsoon?
The absolute absence of dust particles in the desert sky
Atmospheric subsidence and upper-level dry air inversion
Freezing geothermal pressure cells near the surface
The immediate freezing of condensation nuclei
Explanation
The upper atmospheric anti-cyclonic circulation and subsidence of dry air masses over Rajasthan, combined with lack of mountain barriers, create an inversion layer that suppresses cloud formation.
Q35
Under Koeppen's system, the 'Aw' climate symbol denotes which specific climatic setup across large parts of the Indian Peninsula?
Steppe semi-arid interior zone
Tropical Savanna with a distinct dry winter
Humid subtropical northern plain block
Extreme cold mountain tundra zone
Explanation
The 'Aw' symbol represents a Tropical Savanna climate type, characterized by a distinct dry winter season, covering most of the peninsular plateau area south of the Tropic of Cancer.
Q36
What term is traditionally used to describe the local winter rain received over the plains of Punjab and Haryana, vital for Wheat crops?
Kalbaisakhi
Mahawat
Loo Surge
Cherry Bloom
Explanation
The winter rainfall caused by Western Disturbances in northwestern India is locally referred to as 'Mahawat' or 'Mawat', and is highly beneficial for Rabi agriculture.
Q37
Which of the following mountain ranges acts as a barrier to the Bay of Bengal branch of the monsoon, forcing it to cause exceptionally heavy rain in Meghalaya?
Zanskar Range
Garo, Khasi, and Jaintia Hills

Satpura Range
Explanation
The Garo, Khasi, and Jaintia Hills in Meghalaya intercept the Bay of Bengal branch of the southwest monsoon, funneling the winds and causing extreme orographic precipitation.
