What is the News?<\/b><\/h5>\n

The National Oceanic and Atmospheric Administration<\/strong> (NOAA) has <\/span>declared<\/span> that La Ni\u00f1a has re-developed.\u00a0<\/span><\/p>\n

What is Double Dip La Nina?<\/b><\/h5>\n

La Nina is one part of the El Nino Southern Oscillation<\/strong> (ENSO) cycle. But when two La Ninas happen one after the other (with a transition through ENSO neutral conditions in between) is not uncommon. This is usually referred to as a \u2018double-dip\u2019.\u00a0<\/span><\/p>\n

In 2020, La Nina developed during the month of August and then dissipated in April 2021 as ENSO-neutral conditions returned.<\/span><\/p>\n

What is La Nina?<\/b><\/h5>\n

La Ni\u00f1a is a weather pattern that can occur in the Pacific Ocean every few years.\u00a0<\/span><\/p>\n

In a normal year, winds along the equator push warm water westward. Warm water at the surface of the ocean blows from South America to Indonesia. As the warm water moves west, cold water from the deep rises up to the surface. This cold water ends up on the coast of South America.<\/span><\/p>\n

In the winter of a La Ni\u00f1a year, these winds are much stronger than usual. This makes the water in the Pacific Ocean near the equator a few degrees colder than it usually is. Even this small change in the ocean\u2019s temperature can affect weather all over the world.<\/span><\/p>\n

Impact of La Nina<\/b><\/p>\n

La Ni\u00f1a results in heavy or better monsoon rains in India, droughts in Peru and Ecuador, heavy floods in Australia, and high temperatures in the Indian Ocean and Western Pacific.\u00a0<\/span><\/p>\n

What’s the difference between El Ni\u00f1o and La Ni\u00f1a?<\/b><\/h5>\n

Both events start in the Pacific Ocean, but they are opposites in almost every other way. La Ni\u00f1a causes the water in the eastern Pacific to be colder than usual. In the same region, El Ni\u00f1o can cause the water to be warmer than usual. So, areas that are hit with drought during La Ni\u00f1a years can get lots of rain in El Ni\u00f1o years!<\/span><\/p>\n
