India to see warmer summer as El Nino conditions continue

India is likely to experience a warmer start to the summer season this year with El Nino conditions predicted to continue through the season.

El Nino refers to a band of warm water spreading from west to east in the equatorial Pacific Ocean.

Similarly, a La Nina occurs when the band of water spreads east-west and is cooler. Both phenomena can have drastic effects on economies that depend on rainfall.

An El Nino year creates a miniature global-warming crisis, since the warm water spreading across the tropical Pacific releases a large amount of heat into the atmosphere.

La Nina conditions — generally associated with good monsoon rainfall in India — are likely to set in by the second half of the monsoon season.
