“We can expect La Nina conditions to set in during the next few months. We will soon issue a forecast on temperatures for the post monsoon season,” said M Mohapatra, director general, India Meteorological Department.

La Nina refers to the periodic large-scale cooling of the ocean surface temperatures in the central and eastern equatorial Pacific Ocean, coupled with changes in the tropical atmospheric circulation, including changes in winds, pressure and rainfall patterns.

Typically, La Nina brings climate impacts that are the opposite of El Nino (which refers to the warming of oceans), especially in tropical regions.
