How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- The Victoria Mode is a Pacific oceanic cycle that can influence moisture transport towards India.
- Semi-arid zones in north-west India are reported to be expanding.
- The Indian Ocean Dipole is a separate climate mode of the Indian Ocean, not the Pacific.
- The India Meteorological Department (IMD) is under the Ministry of Earth Sciences, and IITM Pune is also an MoES institute.
ಮೇನ್ಸ್
GS-I (Climatology) and GS-III (Environment): Pacific climate modes such as the Victoria Mode can alter moisture flow towards India, expanding semi-arid zones in the north-west. The result is risk to food supply and migration or displacement. Way forward: better climate-mode monitoring and forecasting, drought-resilient crops, efficient water management and climate-adaptive planning for vulnerable districts.
