What effect does El Nino have on monsoon rainfall in India?

The El Nino weather phenomena is gaining strength. Later global forecasts indicate potentially affecting the south west from June to September monsoon of India. El Nino, characterized by warming of surface temperatures in the Pacific Ocean, is associated with lower than normal monsoon rainfall in India.

How does El Nino affect drought?

During El Niño episodes the normal patterns of tropical precipitation and atmospheric circulation are disrupted, hence triggering extreme climate events around the globe: droughts, floods and affecting the intensity and frequency of hurricanes.

How South West monsoon in India is affected by El Nino and Lanino?

El Niño has a warming influence on global temperatures, while La Niña has the opposite effect. In India, for example, El Niño is associated with drought or weak monsoon, while La Niña is associated with strong monsoon and above average rains and colder winters.
