- Statement 1 is correct. The IMD uses specific criteria to declare the monsoon onset, including the requirement that 60% of 14 designated weather stations in Kerala must record a minimum of 2.5 mm of rainfall for two consecutive days.
- Statement 2 is incorrect. The Madden-Julian Oscillation (MJO) is not a low-pressure area over India. Instead, it is an atmospheric phenomenon that travels eastward around the globe and can enhance rainfall activity by influencing the atmospheric conditions conducive to monsoon development.
- Statement 3 is correct. The early onset of the monsoon positively impacts water resource management by helping to recharge groundwater levels and fill reservoirs, which are crucial for sustaining agriculture and other water needs.
Thus, only statements 1 and 3 are correct. Therefore, the correct answer is Option B: 1 and 3 Only.
