IMD announces southwestern monsoon in the Bay of Bengal and the Andaman Sea | Indian News
The Indian Meteorological Department (IMD) formally announced the southwest monsoon in certain areas of the Gulf of Southern Bengal, the South Anderian Sea, the Nicobar Islands and the Northern Andaman Sea, one of the earliest regions in the past seven years.
The average date for monsoon attacks in the region is May 21, but this year begins at least one week ahead of May 13. The premature attack was after two days of heavy moderate to heavy rains on the Nicobar Islands, one of the main parameters for the IMD to announce the start of the monsoon.
“The conditions are still favorable for further advancement towards the southwest monsoon into the Southern Arabian Sea, the Maldives and Comorin regions; other areas of the South Bay of Bengal; the entire Andaman and Nicobar Islands; the remainder of the Andaman Sea; and the central region of Bangladesh for the next three to four days.”
Advantages behind early attacks
Mrutyunjay Mohapatra, Director General of the Meteorological Department of India, mentioned several factors responsible for this premature birth, such as:
- The lowest temperatures in northern India are above average
- Enhance the westerly wind and Easterly at several atmospheric levels.
- Southern India often rains for more than 40 days before the monsoon.
- High pressure anomalies in the northwest Pacific.
“All of these indicators also point to early monsoon attacks in Kerala.” The model’s predictions suggest that the monsoon will arrive in Kerala on May 27, nearly five days higher than the normal June 1 attack.
Rainfall is expected to be higher than normal this year
This year, monsoon precipitation is expected to be higher than normal as expected precipitation should be in the June-September season, accounting for 105% of the long-term average (LPA) 880 mm. The southwest monsoon in India is the main rainy season, providing more than 70% of the country’s rainfall each year.
