One of ENSO’s most important influences is to the Indian Monsoon—the large-scale circulation pattern that brings the Indian subcontinent the vast majority of its yearly rainfall. … El Niño generally suppresses monsoon rainfall; La Niña generally increases it.
How does the El Nino affect the climate of India?
El-Nino increases the surface temperature of the sea and affects the movement of monsoon winds in the Indian Ocean and causes weak drought-like situation in the Indian sub continent.
How El Nino affect India?
ENSO and India
El Nino: Strong El Nino events contribute to weaker monsoons and even droughts in India Southeast Asia. La Nina: The cold air occupies a larger part of India than the El Nino cold air. … This generally benefits the Indian economy, which depends on the monsoon for agriculture and industry.
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.
How does El Nino affect the climate?
El Niño can affect our weather significantly. … 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.
What is El Nino and what are its effects?
The term El Niño (Spanish for ‘the Christ Child’) refers to a warming of the ocean surface (or above-average sea surface temperatures) in the central and eastern tropical Pacific Ocean. El Niño events can disrupt normal weather patterns in the United States and globally. …
What is El Nino and La Nina examine their effects on India’s climate and rainfall?
For India, El Nino during winter results in development of warm conditions. During summer, it leads to dry conditions and deficient monsoon, leading to droughts and water scarcity. Whereas La-Nina brings rains and stronger monsoon in India, it may cause flood like situation in coastal areas.
How do El Nino and Southern Oscillation control the climate of India?
As those conditions change, with the monsoon being linked to El Nino-Southern Oscillation phenomena, summer temperatures over much of India may rise to as high as 45 degrees Celsius, while the Indian Ocean is much cooler.
How does El Nino affect Indian Ocean?
During an Indian Ocean El Niño, the southwesterly summer monsoon is much weaker, and less moisture is being advected over India. … Instead, the ocean responds passively to atmospheric forcing: shifts in global atmospheric sea level pressure and surface winds that appear to be related to ENSO in the Indo-Pacific region.
What is the effect of El Nino?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
What are two effects of El Nino?
(i) The presence of the EL-Nino leads to an increase in sea-surface temperatures. (ii) It weakens the trade winds in the regions and causes heavy rainfall, floods or droughts in different regions of the world.
What is El Nino effect class 10?
The El Nino effect refers to uneven climatic changes due to rise in temperature. It leads to increased melting of polar ice caps as well as other places like the Himalayan snow caps. This results in the rise in the sea level which can submerge many coastal areas, thus resulting in biodiversity loss.
What is El Nino effect Class 9 Ncert?
‘El Nino’ is a Spanish word meaning ‘the child’, and refers to the baby Christ, as this current starts flowing during Christmas. The presence of the El Nino leads to an increase in sea-surface temperatures and weakening of the trade winds in the region.
How does El Niño affect the climates in the mid Pacific region?
During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.
How does El Niño and La Niña affect global climate?
El Niño and La Niña affect not only ocean temperatures, but also how much it rains on land. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
Is El Niño climate or weather?
El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. … El Niño has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America and beyond.
