Q31
The tropical cyclones that cause widespread damage on the eastern coast of India during autumn originate mostly over which water body?
The Arabian Sea
The Bay of Bengal
The Caspian Sea
The Red Sea
Explanation
During the retreating monsoon season (October–November), severe tropical cyclones originate over the Andaman Sea/Bay of Bengal and travel westwards, hitting Odisha, Andhra Pradesh, and Tamil Nadu.
Q32
What is the collective name given to the pressure variations in the southern Pacific Ocean and Indian Ocean that are coupled with El Niño, affecting the Indian Monsoon?
Madden-Julian Oscillation
Southern Oscillation
North Atlantic Oscillation
Walker Circulation Shift
Explanation
The Southern Oscillation (SO) refers to the seesaw pattern of atmospheric pressure between the eastern Pacific (Tahiti) and western Pacific/Indian Ocean (Darwin), coupled with El Niño as ENSO.
Q33
Which structural atmospheric line acts as the dividing axis for the two main branches of the Southwest Monsoon over central India?
The Tropic of Cancer
The Monsoon Trough Axis
The Subtropical Ridge
The Equatorial Inter-Convergence Line
Explanation
The Monsoon Trough serves as the low-pressure axis where the Arabian Sea branch and the Bay of Bengal branch converge over Central Northern India.
Q34
Which region of India receives a substantial part of its winter rainfall from weak warm-core tropical depressions moving from the South Bay of Bengal?
The Malabar Coast
The Coromandel Coast
The Konkan Plain
The Chota Nagpur Margin
Explanation
During the retreating monsoon season, the southeastern coast, especially coastal Andhra Pradesh and Tamil Nadu, experiences heavy rainfall events from low-pressure areas migrating from the Bay of Bengal.
Q35
Which of the following local tracking index conditions denotes a 'Break' situation in the Indian summer monsoon rainfall pattern?
Heavy rainfall localized strictly on the central Indian Peninsula
Dry spell over the plains with heavy downpours along the Himalayan foothills
Disappearance of convective thunderstorms in Northeast India
Complete stagnation of trade winds below the equator line
Explanation
A monsoon break occurs when the pressure drops near the foothills of the Himalayas, shifting rains away from the central agricultural plains to the mountain tracks.
Q36
In Koeppen's climatic map of India, the letters 'Cwg' signify which type of macro-regional climate pattern?
Tropical Savanna Type
Monsoon Type with Dry Winter
Semi-Arid Steppe Type
Polar Ice-Cap Type
Explanation
The 'Cwg' designation is used by Koeppen to represent the Monsoon type climate with dry winters, which dominates the Indo-Gangetic Plains of Northern India.
Q37
The air mass that creates the hot, suffocating daytime 'Loo' winds originates mostly over which geographic region?
The Chota Nagpur Plateau
The Thar Desert and Arid Western Areas
The Tibetan High Ice Shield
The Bay of Bengal maritime zone
Explanation
The hot and dry air mass responsible for the 'Loo' winds originates over the desert tracts of Rajasthan and the adjoining arid areas of Pakistan.
Q38
Which region of India shows the lowest seasonal variation or range of temperature between summer and winter seasons?
The Indo-Gangetic Plains
The Southern Coastal Strip
The Thar Desert Core
The Western Himalayan Tracts
Explanation
Due to the moderating influence of the ocean, the coastal plains of Southern India, particularly the Malabar Coast, display low annual variations in temperature.
Q39
Which tracking factor serves as a major indicator to confirm the real-time onset date of the Southwest Monsoon over the mainland of India?
A sudden drop in water temperature across the Chilika Lake
Sustained rainfall over designated stations in Kerala accompanied by deep westerlies
The complete freezing of high-altitude passes in Sikkim
The development of a high pressure cell over the Sundarbans Delta
Explanation
The IMD uses a sustained increase in rainfall over defined stations in Kerala, along with westerly wind depth and Outgoing Longwave Radiation (OLR) values, to declare monsoon onset.
Q40
The unexpected orographic compression rainfall known as 'Nor'westers' in eastern India is primarily driven by which mechanism?
The descent of freezing dry air from the Pamir Knot
The intense convergence of dry continental air with moist maritime Bay of Bengal air
The direct mechanical blockage generated by the Arakan mountains
The warm ocean current circulation within the Palk Strait
Explanation
Nor'westers or Kalbaisakhi are severe local convective storms that develop due to the collision of hot, dry continental air masses with warm, moist maritime air masses from the Bay of Bengal.
