Exam Strategy
UPSC Prelims frequently tests monsoon mechanism (ITCZ shift, pressure systems), El Niño/La Niña impacts on Indian rainfall, and year-specific monsoon predictions. Questions focus on cause-effect relationships between ocean-atmosphere interactions and monsoon variability. Common error: confusing El Niño warming patterns with La Niña cooling effects on Indian rainfall.
High-yield hooks
1
ITCZ shift northward drives southwest monsoon onset
2
El Niño = weak monsoon, deficient rainfall
3
La Niña = strong monsoon, excess rainfall
4
Pressure gradient between Indian Ocean and landmass
5
SOI (Southern Oscillation Index) predicts monsoon strength
