Q41
Which of the following thermal indices indicates a strong, well-developed rainy season over the Indian subcontinent based on sea surface temperature deviations across the equatorial Pacific?
El Niño Phase
La Niña Phase
Negative Indian Ocean Dipole
Weakened Madden-Julian Oscillation
Explanation
La Niña represents the periodic cooling of sea surface temperatures in the central and eastern equatorial Pacific, which strengthens the Walker Circulation and typically favors a stronger Indian summer monsoon.
Q42
The Western Ghats block the Arabian Sea branch of the monsoon, resulting in a stark precipitation drop toward the east. What is this dry eastern side called?
Orographic Windward Zone
Rain-Shadow Zone
Convective Core Belt
Frontal Submergence Plain
Explanation
The eastern side of the Western Ghats is known as the rain-shadow zone because the air descends, warms adiabatically, and loses its capacity to cause precipitation.
Q43
Which of the following months marks the peak transition stage for the retreating monsoon across the Indian subcontinent?
May
October
January
June
Explanation
October and November form the main period of the retreating or northeast monsoon, acting as a transition phase from the hot-rainy season to dry winter conditions.
Q44
The Arabian Sea branch of the southwest monsoon enters India through which region first?
The Sundarbans Delta
The Western Coastal Plains / Malabar Coast
The Coromandel Coastline
The Gujarat Peninsular Margin
Explanation
The Arabian Sea branch first strikes the western coast of India, specifically hitting the coast of Kerala in early June.
Q45
Which state in India experiences the maximum frequency of violent dust storms during the peak summer months of May and June?
Kerala
Rajasthan
Assam
Odisha
Explanation
Due to intense convective heating and its arid geography, Rajasthan experiences frequent dust storms (Andhi) during the dry summer season.
Q46
According to Koeppen's classification system, the abbreviation 'Amw' corresponds to which description of the Indian climate?
Polar tundra style zone
Tropical Monsoon with a short dry winter season
Arid desert layout with absolute zero rainfall
Sub-tropical humid zone with no dry window
Explanation
In Koeppen's system, 'Amw' represents a Tropical Monsoon climate with a short dry winter season, found along the west coast of India.
Q47
Which high-altitude feature splits into two branches due to the physical barrier of the Tibetan plateau during winter?
The Equatorial Trade Stream
The Subtropical Westerly Jet Stream
The Tropical Easterly Current
The Somali Low Level Jet
Explanation
The Subtropical Westerly Jet Stream flows across Asia in winter and is bifurcated into northern and southern branches by the high Tibetan Plateau block.
Q48
The convective pre-monsoon rain that happens over the plains of south India is called 'Mango Showers' because it aids the ripening of mangoes. What is it locally called in Karnataka?
Kalbaisakhi
Cherry Blossoms / Coffee Showers
Loo Track
Bhur Wind
Explanation
In Karnataka, these pre-monsoon showers are popularly known as 'Cherry Blossoms' or 'Coffee Showers' as they trigger coffee flowering, but they are also referred to as a specific type of Mango Shower.
Q49
The multi-week dry spell observed within the active phase of the southwest monsoon is structurally linked to which atmospheric event?
The strengthening of the Tropical Easterly Jet
The northward shift of the monsoon trough axis
The lowering of sea surface temperatures in the Arabian Sea
The formation of a deep low-pressure center over Mumbai
Explanation
A monsoon break occurs over the plains when the low-pressure monsoon trough shifts northwards toward the foothills of the Himalayas, leaving Central India dry.
Q50
Which mountain system acts as an effective geographical guide to channel the Bay of Bengal branch of the southwest monsoon deep into the Indo-Gangetic Plains?
The Aravalli Range
The Himalayas
The Satpura Range
The Western Ghats
Explanation
The Himalayan range blocks the northward movement of the Bay of Bengal monsoon branch, deflecting these moisture-laden winds westwards along the Indo-Gangetic Plains.
