Northeast monsoon to end peninsular India

The Indian Meteorological Department (IMD) said on Thursday that northeast monsoon rains are likely to occur in Peninsular India from Friday. The peninsular region received normal rainfall at 109% of the long-term average (LPA) after a two-year deficit. Last year, the southern peninsula received only 66% of the LPA and 86.1% in 2017.

Meteorologists said that in 2019, a positive Indian Ocean dipole (IOD) resulted in good rains in the northeast monsoon region.

The IOD is characterized by warm sea surface temperatures in the equatorial Indian Ocean. Positive IOD conditions are associated with normal monsoons. Rainfall across the country in the post-monsoon season (October to December) was significantly above normal at 129% of LPA compared to 56% in 2018.
Rainfall was above average at 110% of LPA during the southwest monsoon season (June to September) in 2019. Central India and South Peninsular India received 129% and 116% of LPA rainfall during the summer monsoon season respectively.

The onset of the southwest monsoon was delayed due to the presence of weak El Niño and very little rainfall in June. The month ended with a 33% decrease in rainfall. The summer monsoon was also long for 39 days. The IMD officially announced the withdrawal of the monsoon on 30 September, but the rains continued, followed by excessive rainfall during the monsoon season.
