Q11
According to the Koeppen climate classification, which symbol represents the monsoon type climate with a short dry summer season found along the western coast of India?
As
Amw
Aw
Bshw
Explanation
The 'Amw' symbol denotes a tropical monsoon climate with a short dry season, characteristic of the West Coastal Plains, Tripura, and the Andaman and Nicobar Islands.
Q12
How does a positive phase of the Indian Ocean Dipole (IOD) generally impact the summer southwest monsoon over India?
It delays the onset and reduces rainfall severely
It enhances convective activity and increases monsoon rainfall
It forces the monsoon to retreat prematurely in August
It has no measurable structural impact on Indian precipitation
Explanation
A positive IOD involves warmer sea surface temperatures in the western Indian Ocean, which enhances convective activity and leads to above-normal monsoon rainfall over India, often countering El Niño.
Q13
The dry, scorching, and dusty local winds known as 'Loo' blow during the afternoon hours of summer across which region of India?
The Great Northern Plains
The Western Ghats
The Malabar Coast
The Northeast Hills
Explanation
The Loo is a strong, dusty, hot, and dry summer wind that blows across the Great Northern Plains of India, including Punjab, Haryana, Uttar Pradesh, and Bihar.
Q14
Which branch of the southwest monsoon is responsible for delivering heavy precipitation to the Arakan Yoma hills in Myanmar and subsequently northeastern India?
Arabian Sea Branch
Bay of Bengal Branch
South-East Equatorial Current
Somali Current Branch
Explanation
The Bay of Bengal branch strikes the coast of Myanmar and parts of southeast Bangladesh, where it is deflected by the Arakan Yoma mountains towards northeast India and the Ganga plains.
Q15
The pre-monsoon rainfall known as 'Mango Showers' is highly beneficial for the early ripening of mangoes in which group of states?
Punjab and Haryana
Karnataka and Kerala
West Bengal and Assam
Rajasthan and Gujarat
Explanation
Mango showers are pre-monsoon showers that occur towards the end of the summer season in Karnataka and Kerala, aiding in the ripening of mangoes.
Q16
The intense low-pressure cell that develops over northwest India during summer draws winds across the equator from which high-pressure area?
The Siberian High
Subtropical High Pressure cell of the Southern Indian Ocean
The Tibetan Plateau High
The Mediterranean Low pressure zone
Explanation
The summer low-pressure system over India pulls the southeastern trade winds from the subtropical high-pressure cell located over the southern Indian Ocean (near Madagascar).
Q17
The winter precipitation in northwestern India is highly beneficial for which of the following agricultural crops?
Rice
Wheat
Cotton
Jute
Explanation
Winter rain caused by Western Disturbances is crucial for Rabi crops, especially Wheat, in states like Punjab, Haryana, and Western Uttar Pradesh.
Q18
Which of the following meteorological stations in India records a distinct winter rainfall maximum, primarily from the Northeast Monsoon?
Mumbai
Chennai
Kolkata
New Delhi
Explanation
Chennai, located on the Coromandel Coast, receives the majority of its annual rainfall between October and December from the retreating/northeast monsoon winds picking up moisture from the Bay of Bengal.
Q19
The 'Somali Jet Stream' (or Findlater Jet) plays a critical role in Indian meteorology by performing which function?
Pushing western disturbances away into Central Asia
Steering cross-equatorial monsoon winds toward the Indian coast
Creating severe cold wave conditions over north India
Suppressing the formation of tropical cyclones in the Bay of Bengal
Explanation
The Somali Jet Stream is a low-level cross-equatorial jet that steers moisture-laden winds across the western Indian Ocean directly toward the southwest coast of India.
Q20
Which structural feature acts as a barrier, preventing cold Siberian winds from entering the Indian subcontinent during winter?
The Vindhyan Range
The Himalayas
The Karakoram Pass
The Aravalli Range
Explanation
The high wall of the Himalayan mountain range effectively blocks the freezing, dry continental air masses originating over Central Asia and Siberia from plunging into northern India.
