Monsoon stalls over Maharashtra due to weak winds and lack of supporting systems
The southwest monsoon's progress has stalled over Maharashtra, resulting in a significant rainfall deficit. This delay is attributed to several factors: weakened monsoonal winds from the Arabian Sea, dominant northerly/northwesterly dry winds acting as barriers, and a lack of supporting weather systems like low-pressure areas or offshore troughs. Additionally, the Madden-Julian Oscillation (MJO) is not in a favorable phase. This situation indicates a delayed onset and greater uncertainty for Maharashtra, while the monsoon is expected to advance in other eastern regions in the coming days.
Key Points
- The southwest monsoon's progress has stalled over Maharashtra, leading to a substantial rainfall deficit.
- Weakened monsoonal winds from the Arabian Sea and dominant dry northerly/northwesterly winds are key contributing factors.
- The absence of supporting weather systems like low-pressure areas or offshore troughs further impedes monsoon advancement.
- The Madden-Julian Oscillation (MJO) is currently not in a favorable phase for rainfall over India.
- Maharashtra faces a delayed monsoon onset, while eastern regions like Telangana, Odisha, and Bihar are expected to see advancement soon.
Exam Facts
