According to IMD's classification, a 'deficient' monsoon is one where rainfall is below what percentage of the Long Period Average (LPA)?
- 85%
- 90%
- 95%
- 100%
Answer: 90%
IMD categorizes monsoon performance based on deviation from the LPA. Rainfall below 90% of the LPA is classified as 'deficient', which raises concerns about drought conditions. This classification helps in disaster preparedness and agricultural policy formulation.
