It is also sometimes called El Viejo, anti-El Nino, or simply "a cold event."La Nina events represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific.La Nina event is observed when thewater temperature in the Eastern Pacific gets comparatively colder than normal, as a consequence of which, there is a strong high pressure over the eastern equator...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.In the ‘La Nina year’, rainfall associated with the summer monsoon in Southeast Asia tends to be greater than normal, especially innorthwest India and Bangladesh.It usually brings in colder than normal wintersin India.Apr 16, 2024 · It has two opposite states: El Niño and La Niña, both of which significantly alter global weather.
