Influence of El – Nino on the Climate of India


Weather conditions in India are also influenced by EI-Nino which causes wide spread floods and droughts in tropical regions of the world.

El-Nino is a narrow warm current which sometimes appears off the coast of Peru in South America.

It is a temporary replacement of the cold Peru Current which normally flows along this coast.

Sometimes it increases the surface water temperatures of the sea by 10° C.

This warming of tropical Pacific waters affects the global pattern of pressure and wind systems including the monsoon winds in the Indian Ocean.

It is believed that the severest drought of 1987 over India was caused by EI-Nino.
