The study states that the Bengal Basin lies in the path of the Bay of Bengal branch of the summer monsoon. It is very sensitive to monsoons. Even a slight change in the monsoon can affect the region’s agriculture-based socioeconomic conditions.
The Birbal Sahni Institute of Palaeology (BSIP) has reconstructed the history of monsoons in the region. In a hydroclimatic history of approximately 10,200 years, scientists have found that the region experienced heavy rainfall for 100,000 to 5,600 years, with a decline in the last 4,300 years. To arrive at their findings, the scientists collected sediment samples from the bottom of a dry lake bed in the northern part of the Bengal basin. Then, with the help of technology, other information was collected.
On the other hand, severe winter continues in North India. However, a report has also said that the country may have to face severe heat and a heat wave this year. It can also affect the monsoon. The reason for this is being told by El Niño. At the same time, there is a La Niña effect on the climate, so the cold snap is greater, while the El Niño effect can last from July to September this year. This is the monsoon season. El Niño has more effect, monsoon rains can be affected.
