Q21
Why does the western slope of the Western Ghats receive vastly more rainfall than the eastern slope (Deccan Plateau)?
The eastern slope lacks vegetation cover altogether
The western slope forces orographic precipitation while the eastern slope is a rain-shadow zone
The eastern slope experiences higher atmospheric pressure cells all year round
Cold maritime currents only affect the western shoreline
Explanation
The western slope acts as an orographic barrier to the Arabian Sea branch of the southwest monsoon, forcing the air to rise and condense, while the eastern side sits in the dry rain-shadow zone.
Q22
Which upper atmospheric wind system suddenly withdraws from the Indian plains south of the Himalayas to facilitate the onset of the summer monsoon?
Tropical Easterly Jet Stream
Subtropical Westerly Jet Stream
Polar Jet Stream
Somali Jet Stream
Explanation
The northward shift and withdrawal of the Subtropical Westerly Jet Stream from the south of the Himalayas is a prerequisite for the establishment of the summer monsoon over India.
Q23
During El Niño years, how is the Indian southwest monsoon typically affected?
It leads to unprecedented heavy flooding across India
It typically results in deficient rainfall and drought conditions
It forces an early monsoon onset in the first week of May
It eliminates the occurrence of the 'October Heat' phenomenon
Explanation
El Niño causes the accumulation of warm water in the eastern Pacific Ocean, weakening the convective pressure setup over the western Pacific and Indian Oceans, often resulting in deficient monsoon rainfall or drought in India.
Q24
The pre-monsoon showers known as 'Cherry Blossoms' or 'Coffee Showers' occur in which region of India?
Assam hills
Karnataka
West Bengal plains
Kashmir valley
Explanation
Cherry Blossoms or Coffee Showers are local pre-monsoon winds that blow in Karnataka and parts of Kerala, helping in the flowering of coffee plantations.
Q25
The winter rain along the Coromandel coast of India is primarily brought by which of the following wind systems?
Southwest Monsoon Winds
Northeast Monsoon Winds
Western Disturbances
Southwesterly Jet Stream
Explanation
The Northeast Monsoon (or retreating monsoon) winds pick up moisture as they blow over the Bay of Bengal and strike the Coromandel coast, causing winter rainfall between October and December.
Q26
Which structural atmospheric feature over the Tibetan Plateau during summer acts as a critical thermal engine to strengthen the Indian monsoon?
Tibetan Upper Tropospheric Anticyclone
Subtropical High Pressure Ridge
Aleutian Low Pressure System
Siberian High Pressure Cell
Explanation
Intense insolation over the high-altitude Tibetan Plateau creates an intense thermal low-pressure zone at the surface and a strong anticyclone (high pressure) in the upper troposphere, driving the Tropical Easterly Jet.
Q27
The 'Tropical Easterly Jet Stream' (TEJ) establishes itself over India after the onset of summer and is directly associated with which phenomenon?
The intensification and support of the Southwest Monsoon
The generation of winter cold waves in Kashmir
The absolute suppression of pre-monsoon convective thunderstorms
The development of the dry 'Loo' winds over Punjab
Explanation
The TEJ is a seasonal upper-tropospheric wind system that helps maintain the monsoon trough over northern India and steers tropical depressions into the Bay of Bengal.
Q28
In which month does the Southwest Monsoon typically withdraw completely from the northwestern plains of India?
July
August
September
December
Explanation
The withdrawal of the Southwest Monsoon begins from the northwestern parts of India (like Rajasthan) in early September and is largely completed from the northern plains by October.
Q29
Which state or union territory in India receives the minimum annual rainfall?
Ladakh
Punjab
Odisha
Kerala
Explanation
The cold desert region of Ladakh (specifically around Leh) and parts of Western Rajasthan (Jaisalmer) receive the lowest annual rainfall in India, often below 10–15 cm.
Q30
According to the Koeppen classification system, the 'Bshw' (Semi-Arid Steppe) climate zone is predominantly found in which region of India?
The Western Coastal Plain
Rain-shadow zone of the Peninsular Plateau and parts of Rajasthan
The Northeast Frontier mountains
The Ganga-Brahmaputra Delta
Explanation
The Bshw climate type covers a rain-shadow zone extending through the interiors of the Peninsular Plateau (parts of Karnataka, Maharashtra, Andhra Pradesh) and parts of western Rajasthan and Haryana.
