What is El Nino how is it relevant to India?

How does El Nino affect Indian Ocean?

Other studies showed that Indian Ocean basin-wide warming (cooling) contributes to rapid termination of El Niño (La Niña) by inducing zonal wind anomalies over the equatorial western Pacific (Kug and Kang 2006, Izumo et al 2016) and suggested the strong interactions between the Pacific and Indian Oceans (Cai et al 2019 …

What is El Nino impact on Indian Climate Class 9?

El Nino refers to the large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. … El Nino adversely impacts the Indian monsoons and hence, agriculture in India.

What is the effect of El Nino on India’s climate Class 9?

El Nino – Effects on India

The Indian Ocean is warmer than the adjoining oceans and so, has relatively lower pressure. Hence, moisture-laden winds move from near the western Pacific to the Indian Ocean.

What is El Niño impact?

El Niño. During El Niño, trade winds weaken. … El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.

How does El Niño work?

How Does El Niño Work? In normal years, the winds tend to blow from east to west across the waters of the tropical Pacific. … During El Niño years, the winds weaken, causing the upwelling of deep water to cease. The consequent warming of the ocean surface further weakens the winds and strengthens El Niño.

What is El Niño and how is it formed?

El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms. … During El Niño years, such as 1997, the southeast receives more rain than average.
