Climate change due to less rain
Of course, for the last 48 hours, the trough line of monsoon is passing through Bihar. Even after this, the monsoon has remained normal or weak. It is not raining as expected. Dr. A. Sattar, senior meteorologist of Dr. Rajendra Prasad Central Agricultural University, Pusa said that low pressure areas are not being formed in Bihar. Still the low pressure area is being formed away from the normal position towards Odisha. In fact, due to the absence of any system, the expected rain could not occur. According to Dr. Sattar, the reason for the unusual behavior of the monsoon is climate change. He told that low pressure areas are not being formed in Bihar. This is the reason why the monsoon is not being active in a powerful manner. Climate change is behind this. This type of unusual behavior of monsoon is being seen more in the last two decades. El Nino effect is also being seen behind the less rainfall.
