What are the reasons for very little rain in August?
Meteorologists give some immediate reasons for the low rainfall in August – for example, a strong system did not form in the Bay of Bengal, one end of the monsoon trough line moved to the foothills of the Himalayas. Apart from this, El-Nino is being told to be active behind such a situation. Whenever El Nino is active, then the monsoon becomes weak in India. Due to this, there is drought in many states of the country.
El Nino has been active in the Pacific Ocean 14 times in the last 65 years. In these 9 times there was drought on a large scale in India. There, was drought 5 times but its effect was mild. President of Meteorology and Climate Change Skymet G.P. Sharma has expressed the possibility that in 2023 a situation like 1991 may arise. Actually, if there is 10 percent less rainfall than normal, then in the definition of meteorology it is called mild drought or moderate drought year.
