Which of the following statements regarding the atmospheric circulation and weather systems of India are correct?

Select all that apply

Show answer & explanation

Answer: The shift of the monsoon trough toward the Himalayan foothills causes a temporary cessation of rainfall known as a 'break' over the northern plains of India.; Western Disturbances that bring crucial winter precipitation to north-western India are steered into the subcontinent by the Sub-Tropical Westerly Jet Stream.

Answer

The correct statements are that the shift of the monsoon trough toward the Himalayan foothills causes a break in rainfall over the northern plains, and that Western Disturbances are carried into north-western India by the Sub-Tropical Westerly Jet Stream.
The statements confirming that the northward shift of the monsoon trough causes a monsoon 'break' over the northern plains and that the Sub-Tropical Westerly Jet Stream steers Western Disturbances into India during winter are both meteorologically accurate.

Step-by-Step Solution

1
Analyze statement on monsoon break mechanisms
Shift of the low-pressure monsoon trough to the Himalayan foothills reduces rain over the plains and increases rain over the mountains, which constitutes a classic monsoon 'break'.
Topographic and pressure variations govern the position of the monsoon trough.
2
Analyze upper-air circulation during winter (Western Disturbances)
The Sub-Tropical Westerly Jet Stream situated south of the Himalayas during winter transports extra-tropical weather systems (Western Disturbances) from the Mediterranean into India.
Upper-level westerly winds control winter weather patterns over northern India.
3
Evaluate jet stream seasonal movements and monsoon withdrawal spatial sequence
The Sub-Tropical Westerly Jet shifts north of the Himalayas during summer rather than remaining anchored south, and monsoon withdrawal starts in North-West India (Rajasthan), not South India.
Thermal heating of Tibet shifts jet streams northward in summer, while solar retreat initiates land cooling and monsoon withdrawal from the north-west.

Question 207Question →

With reference to the climatic conditions of India during the post-monsoon (retreating monsoon) season, which of the following atmospheric mechanisms is primarily responsible for bringing precipitation to the Coromandel Coast of Tamil Nadu during October and November?

Show answer & explanation

Answer: The North-East trade winds picking up moisture while traversing the Bay of Bengal before hitting the coast.

Answer

The North-East trade winds picking up moisture while traversing the Bay of Bengal before hitting the coast.
During the autumn retreat of the monsoon (October–November), the pressure gradient reverses. The North-East trade winds blow from the high-pressure zone over northern India toward the Bay of Bengal. As they traverse the Bay of Bengal, they absorb moisture and strike the Coromandel Coast of Tamil Nadu, causing major rainfall in this region.

Step-by-Step Solution

1
Analyze the pressure system and wind direction during the post-monsoon season.
During October and November, the sun moves southward, causing the Inter-Tropical Convergence Zone (ITCZ) to shift south of the equator. High pressure develops over northern India, establishing dry North-East trade winds blowing from land towards the sea.
Understanding pressure shifts explains the retreat of the South-West monsoon and the onset of North-East monsoon flow.
2
Trace the path of the North-East trade winds across the Indian subcontinent and Bay of Bengal.
While these winds originate as dry continental winds over northern landmasses, the easterly branch crosses the open waters of the Bay of Bengal, absorbing significant moisture.
Moisture acquisition over the Bay of Bengal is essential for cloud formation and precipitation on the east coast.
3
Determine the impact of these moisture-laden winds on the Coromandel Coast.
When these North-East winds hit the Coromandel Coast of Tamil Nadu, they meet land and release heavy precipitation, making October-November the chief rainy season for Tamil Nadu.
This establishes the exact atmospheric mechanism responsible for the region's winter rainfall.

Arrange the following atmospheric phenomena and upper-air circulation events in the correct chronological sequence leading up to the onset of the South-West Monsoon over the Indian subcontinent.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence begins with intense solar heating of the landmass and Tibetan Plateau, followed by the northward migration of the ITCZ, the sudden withdrawal of the Sub-Tropical Westerly Jet Stream to the north of the Himalayas, and finally the establishment of the Tropical Easterly Jet Stream over southern India.
Monsoon onset follows a defined thermodynamic and dynamic progression: thermal heating of land/Tibet initiates the process, causing the ITCZ to move northward. Subsequently, the Sub-Tropical Westerly Jet Stream shifts north of the Himalayas, allowing the upper-level Tropical Easterly Jet Stream to form and pull cross-equatorial moisture-laden winds across peninsular India.

Step-by-Step Solution

1
Identify the initial thermal trigger for monsoon establishment.
Intense thermal heating of Northern India and the elevated Tibetan Plateau in spring (April-May) creates low surface pressure.
Monsoon circulation is primarily driven by differential heating between land and sea.
2
Trace the movement of the equatorial low-pressure belt.
The Inter-Tropical Convergence Zone (ITCZ) shifts northward to lie over the Indo-Gangetic Plain as the Monsoon Trough.
The thermal trough follows the sun's apparent northward movement.
3
Analyze upper atmospheric jet stream dynamics over Northern India.
The Sub-Tropical Westerly Jet Stream (STWJ) abruptly vacates the region south of the Himalayas and relocates north of Tibet.
The presence of STWJ south of the Himalayas suppresses convection over northern India; its withdrawal allows deep tropical convection.
4
Identify the final atmospheric mechanism for monsoon burst.
The Tropical Easterly Jet Stream (TEJ) forms at upper levels (around 14°N), accelerating the south-west monsoon winds towards the mainland.
Divergence at the upper troposphere over Tibet leads to the outflow of the easterly jet, which pulls cross-equatorial monsoon winds across India.

Semi-clustered settlements are formed due to social segregation and spatial division within a village.
Dominant groups control central areas, forcing other socio-economic groups to live on outer boundaries.
3
Identify the characteristic of Hamleted Settlements
Hamleted settlements feature small, physically separate sub-clusters unified under one overarching village identity, known locally as Nagla, Para, or Panna.
Ethnic or social factors segment the settlement into distinct spatial units.
4
Identify the characteristic of Dispersed Settlements
Dispersed settlements consist of isolated single huts or small clusters scattered across rugged, hilly, or forested landscapes.
Terrain constraints and fragmented resources prevent dense habitation.

Question 220Question →

In the study of human settlements in India, the Census of India categorizes urban places into Statutory Towns and Census Towns. Which of the following sets of quantitative demographic criteria correctly defines a 'Census Town' according to the Census 2011 guidelines?

Show answer & explanation

Answer: A minimum population of 5,000; at least 75% of the male main working population engaged in non-agricultural pursuits; and a population density of at least 400 persons per sq. km.

Answer

The criteria defining a Census Town in India are a minimum population of 5,000, at least 75% of the male main working population engaged in non-agricultural sector work, and a minimum population density of 400 persons per sq. km.
According to the Census of India 2011, urban settlements that do not possess a municipality, corporation, cantonment board, or notified town area committee (Statutory Towns) are classified as 'Census Towns' if they meet three criteria simultaneously: (1) a minimum population of 5,000, (2) at least 75% of the male main working population engaged in non-agricultural pursuits, and (3) a density of population of at least 400 persons per square kilometer.

Step-by-Step Solution

1
Identify the classification categories of urban settlements in Census of India
Urban areas are divided into Statutory Towns (notified under law by state/UT governments) and Census Towns (demographically identified).
To differentiate legal administrative urban status from demographic census-defined urban status.
2
Examine the three specific demographic thresholds for Census Towns
1. Minimum population of 5,000. 2. At least 75% of male main workers in non-agricultural activities. 3. Minimum population density of 400 persons per sq. km.
All three criteria must be fulfilled simultaneously for a village to be classified as a Census Town.
3
Evaluate the choices against the verified 2011 Census criteria
The statement specifying 5,000 minimum population, 75% male main non-agricultural workers, and 400 persons/sq. km density is accurate.
Matching exact census definitions ensures correct identification.
