What factors contribute to above-normal rainfall predictions in India by IMD?
Understand the meteorological aspects leading to the forecast of above-normal rainfall in June.
- Positive Indian Ocean Dipole (IOD) phase: Warmer than usual sea surface temperatures in the western Indian Ocean, leading to increased moisture inflow over India.
- Enhanced monsoon flow: Strengthening of the southwesterly winds, aiding in the transport of moisture-laden air mass over the Indian subcontinent.
- Weakening of El Niño: El Niño conditions typically suppress monsoon rainfall, so any weakening or neutral phase supports above-normal rainfall predictions.
- Low pressure systems: Development of low-pressure systems over the Bay of Bengal can enhance rainfall activities in June.
- Dynamic Monsoon features: Factors like Tropical Cyclones, Madden-Julian Oscillation, and other dynamic features can also influence rainfall patterns.
