GS1History · Society · Geography· Geophysical phenomena (earthquakes, cyclones, volcanoes)· Prelims·
Why in news
Significant regional rainfall disparities between Mumbai and Delhi highlight the impact of geographical location and climate volatility on monsoon patterns.
Background
Mumbai's coastal proximity to the Arabian Sea facilitates heavy rainfall, while Delhi's inland position results in a 1400 km moisture travel distance. El Niño and atmospheric systems are key drivers of these regional variations.
Facts for Prelims
- PlaceMumbai: Coastal city on the Arabian Sea receiving heavy monsoon rainfall.
- S&TEl Niño: Oceanic-atmospheric phenomenon that can weaken monsoon circulation over inland regions like Delhi.
- FactDelhi experiences a rainfall delay due to moisture traveling approximately 1400 km from the coast.
For Mains
Q. Discuss how geographical location and global climatic phenomena like El Niño influence regional rainfall variability and its implications for urban water management in India.
Dimensions to cover in your answer
- Hydrological disparity: Coastal-inland moisture gradient creating unequal water security for metropolitan hubs.
- Climate volatility: Increasing frequency of extreme rainfall events vs prolonged dry spells in inland regions.
- Infrastructure mismatch: Urban drainage systems in Mumbai vs water storage requirements in Delhi.
