Source:the-print ↗

Why It Matters

Provides context on regional weather patterns, monsoon dynamics, and urban flooding issues in Kolkata, which are core topics for West Bengal civil services examinations.

Summary

Heavy rain lashed Kolkata and several other districts in West Bengal, causing disruptions to normal life, traffic congestion, and waterlogging in low-lying areas, driven by active meteorological conditions in the region.

Key Points

  • Heavy rainfall lashed Kolkata and various other districts across West Bengal, disrupting normal life, traffic, and pedestrian movement.
  • The heavy downpours are typically associated with active monsoon conditions, low-pressure systems, or depressions forming over the Bay of Bengal affecting the Gangetic plains of West Bengal.
  • Urban flooding and waterlogging in low-lying areas of Kolkata are recurrent challenges during intense monsoon spells.

West Bengal Geography and Climate

What are the primary climatic divisions and monsoon characteristics of West Bengal?

  • Climate Type: Tropical Monsoon type prevailing across the southern plains, characterized by high humidity and heavy rainfall during summer months.
  • Monsoon Source: Driven primarily by the South-West Monsoon (Bay of Bengal branch), which enters Bengal around early June.
  • Northern Variations: Northern districts (Darjeeling, Kalimpong) experience a humid subtropical to mountain climate with significantly lower winter temperatures and high orographic rainfall.

Cross-Topic Patterns

  • Monsoon Depressions vs Tropical Cyclones

    Bay of Bengal depressions drive both heavy monsoon rains in Kolkata and severe tropical cyclones (like Amphan and Yaas) along the coastal delta.
