Monsoon System — Prelims Strategy
Prelims Strategy
To ace monsoon-related questions in Prelims, aspirants must focus on conceptual clarity and factual accuracy. Begin by thoroughly understanding the fundamental drivers: differential heating, ITCZ, Coriolis effect, and the role of upper-air circulation (STWJ, TEJ).
Memorize the typical onset and withdrawal dates for the Southwest Monsoon and the regions primarily affected by both Southwest and Northeast Monsoons. Pay close attention to the two branches of the Southwest Monsoon (Arabian Sea and Bay of Bengal) and their respective rainfall patterns, especially the orographic effect of the Western Ghats and the rain shadow regions.
A critical area is the impact of El Niño, La Niña, and IOD – understand their mechanisms and how they correlate with monsoon strength. Practice identifying incorrect statements, as UPSC often uses subtle factual errors.
Keep an eye on current affairs related to IMD forecasts, monsoon performance, and any new prediction technologies or climate change impacts, as these are increasingly integrated into questions. Use maps extensively to visualize rainfall distribution and wind patterns.
