What is ‘El Nino’?

El Nino is the rise in the surface temperatures in the tropical Pacific Ocean to above-normal levels for an extended period of time. This increase in the temperature in the Pacific delay the onset of monsoon clouds in the Bay of Bengal. Also, there is possibility that the amount of rain bearing clouds may also be reduced. Because of this, the entry of monsoon may be hindered and the rain may be weakened.
