Why in the news?<\/h2>\n

The US National Oceanic and Atmospheric Administration (NOAA) has predicted that there is a 83% chance that the Oceanic Ni\u00f1o Index (ONI) will move into a neutral range by April-June 2024. It is predicted that El Nino event will not take place due to ONI moving into neutral range<\/span>.<\/p>\n

1) ENSO is measured by two indices- Oceanic Ni\u00f1o Index and Southern Oscillation Index-<\/strong>\u00a0Oceanic Nino Index (<\/span>ONI)<\/span><\/span> is the primary indicator for<\/span> monitoring the ocean part of<\/span>\u00a0 El Ni\u00f1o-Southern Oscillation, or \u201cENSO<\/span>\u201d. Southern Oscillation Index<\/span> (SOI<\/span>) is the primary indicator for monitoring the atmospheric part<\/span> of ENSO.<\/p>\n

2) The ONI tracks the running 3-month average sea surface temperatures in the east-central tropical Pacific between 120\u00b0-170\u00b0W<\/span>, near the International Dateline. It also determines whether they are warmer or cooler than average.<\/p>\n

3) ONI values are used to predict El Ni\u00f1o and La Ni\u00f1a-

What are El Nino and La Nina?<\/h2>\n

Description<\/strong>-El Nino and La Nina are two opposing climate trends that deviate from the normal conditions and normally run 9 to 12 months. El Nino is known as the warm phase and<\/span> La Nina is known as the cold phase of ENSO<\/span>.<\/p>\n

Frequency<\/strong>– These events occur every 2 to 7 years on average<\/span>. El Ni\u00f1o is more frequent than La Nina. They are together referred to as the El Ni\u00f1o-Southern Oscillation (ENSO) cycle by scientists.<\/p>\n

Impacts<\/strong>– Both El Nino and La Nina have global effects on weather, wildfires, ecosystems and economics.<\/p>\n
