Q61
Which of the following regional index variations describes the 'negative phase' of the Indian Ocean Dipole (IOD)?
Warmer waters in the western Indian Ocean near Madagascar
Warmer waters in the eastern Indian Ocean near Sumatra and Indonesia
Complete drying of the equatorial surface currents
The appearance of freezing ice sheets across the Persian Gulf
Explanation
A negative IOD is characterized by warmer sea surface temperatures in the eastern Indian Ocean near Indonesia and cooler temperatures in the western Indian Ocean, which often dampens the Indian monsoon.
Q62
The transition from the rainy season to early winter features a combination of high humidity and clear skies, leading to what specific atmospheric condition?
Winter Inversion
October Heat
Pre-Monsoon Surge
Kalbaisakhi Spell
Explanation
The transition period during October brings clear skies and high humidity over a damp landscape, creating the oppressive daytime weather known as 'October Heat'.
Q63
Which mechanism initializes the physical 'Onset' of the Southwest Monsoon over the south-western coast of India?
The strengthening of the Siberian high pressure system
The northward shift of the ITCZ and arrival of moisture-laden cross-equatorial winds
The southward movement of the Subtropical Westerly Jet below Delhi
The cooling down of the core landmass of Central India
Explanation
The northward shift of the ITCZ and the establishment of the low-level Somali Jet Stream carry dense marine moisture, causing the monsoon burst over Kerala.
Q64
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.
Q65
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.
Q66
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.
Q67
Why does Western Rajasthan receive very low rainfall from the Arabian Sea branch of the southwest monsoon?
The Aravalli Range lies parallel to the monsoon wind direction
The area is dominated by intense sub-surface geothermal activity
The moisture freezes instantly over the Sambhar Lake
Cold maritime air masses create a permanent inversion layer
Explanation
The Aravalli Range lies parallel to the direction of the Arabian Sea monsoon winds, failing to provide an effective orographic barrier to force the winds to rise.
Q68
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.
Q69
Which of the following regional index variations describes the 'negative phase' of the Indian Ocean Dipole (IOD)?
Warmer waters in the western Indian Ocean near Madagascar
Warmer waters in the eastern Indian Ocean near Sumatra and Indonesia
Complete drying of the equatorial surface currents
The appearance of freezing ice sheets across the Persian Gulf
Explanation
A negative IOD is characterized by warmer sea surface temperatures in the eastern Indian Ocean near Indonesia and cooler temperatures in the western Indian Ocean, which often dampens the Indian monsoon.
