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.
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. It is associated with high pressure in the western Pacific. El Nino adversely impacts the Indian monsoons and hence, agriculture in India.
How does La Nino affect Indian monsoon?
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.
How does La Niña affect India?
El Niño has a warming influence on global temperatures, whilst La Niña has the opposite effect. In India for example, El Nino is associated with drought or weak monsoon while La Niña is associated with strong monsoon and above average rains and colder winters.
How does El Nino and La Niña affect Indian monsoon answer?
there is a general association between El Nino and monsoon drought for South Asia (and La Nina with monsoon flood). … So an El Nino warming, which generates anomalous precipitation and hence ascent in the central-to-east Pacific, also generates anomalous subsidence over the Indian Ocean region.
What are the effects of La Nina?
La Niña typically means:
Warmer overnight temperatures (in the north) Shift in temperature extremes. Decreased frost risk. Greater tropical cyclone numbers.
What is El Nino effect?
El Nino is a climate pattern that describes the unusual warming of surface waters in the eastern 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. …
How does La Nina affect winter in India?
It is characterised by the unusual cooling of the central and east-central equatorial Pacific Ocean. It usually brings in colder than normal winters in India. … La Niña could be bringing warmer air from the North into India, according to Raghu Murtugudde, climate scientist at the University of Maryland.
What is the difference between El Niño and La Niña?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
