Jump to: • • • • El Niño is officially back. It's been a few years since we were last impacted by the irregular weather pattern, so it's likely time for a refresher on exactly what that means and how it may affect the weather where you live. The What is El Niño? El Niño (Spanish for "the boy") is a climate pattern in the Pacific Ocean, but it can impact the weather worldwide. According to the In simple terms, El Niño is a change in that typical pattern. During El Niño conditions, the trade winds weaken and the warm winds are pushed toward the west coast of the U.S. and South America. What are the effects of El Niño? In the U.S., we can expect to see the strongest effects from El Niño in the late fall and winter, How often does El Niño Occur? Typically, El Niño conditions occur every two to seven years and the conditions last for nine to twelve months. The And what about La Niña? La Niña occurs less often than El Niño and essentially creates the opposite conditions. La Niña patterns see colder temperatures near the equator in the Pacific Ocean.

Editor’s note: The following was originally published on May 24, 2023. It has been edited for context. What is El Niño? El Niño is a weather phenomena when there is abnormally warm sea surface temperature in the Pacific Ocean. It can affect weather patterns across the world, with most of the impact hitting the United States in the fall and winter, said David DeWitt, director of the National Oceanic and Atmospheric Association’s Climate Prediction Center. Watch La Niña fade and El Niño approach in the tropical Pacific Ocean in 2023. For a deeper look check out this post Early weather predictions for California It’s going to be a hot summer in California. Dr. Paul Ullrich, professor of regional and global climate modeling at UC Davis, predicts that the Northern California region may see humid heat waves this summer due to the winter downpour, but El Niño doesn’t necessarily have a hand in it. May 19, 2023 5:00 AM “The effect is very small,” said Ullrich. “You can’t say that El Niño is the reason why we had an extreme heat wave.” Early predictions for California show that most of the state will have near-average rain from October to December, with the exception of the northernmost regions where it is below normal. “This prediction is going to change,” DeWitt said. “It’s going to change every month as this El Niño evolves...” Early forecasts for fall and winter seasons Most of the impact of El Niño will be in the southern part of the globe, down past Southern California and Me...

Dr Kieran Hunt, a climate scientist at the University of Reading and the National Centre for Atmospheric Science, explains what El Niño is and what it means for our weather, our climate, economy, and health. What is El Niño? El Niño is a climate pattern that is defined as anomalous warming of surface and sub-surface waters in the eastern and central tropical Pacific Ocean. More specifically, El Niño is the name given to the warm phase of a larger phenomenon called the “El Niño-Southern Oscillation” (ENSO). El Niño’s greatest impact is in the winter, and it typically lasts for about a year, but it can last for much longer, which we recently saw with the recent La Niña (the cool phase of ENSO), which lasted for three years. It occurs irregularly, roughly every 2-7 years. El Niño acts as a giant heat source in the tropics, in turn affecting atmospheric circulation, which then influences global climate and weather patterns worldwide. Will El Niño come into effect this summer? El Niño tends to peak in the winter months, so we expect to see El Niño continue to grow through the summer until at least the autumn. The World Meteorological Organisation outlook published in April gave a 60% chance of transition to El Nino in May-July, rising to about 80% before the end of October. Last week, NOAA – the National Oceanic and Atmospheric Administration in the US – officially declared the onset of El Niño. What effect does El Niño have on global temperatures? We know that El Niño can warm...

The reason lies within the definition of an El Niño. An El Niño is a natural, temporary and occasional warming of part of the Pacific that shifts weather patterns across the globe. With El Niño starting before summer even officially begins, there’s a lot more heating up on the way as El Niño grows toward its usual peak in winter. “The global oceans are very warm right now and I’m afraid that this is putting us into territory that we don’t have much experience with,” said National Weather Service meteorologist Michelle L’Heureux in an interview with The last “super” El Niño, from 2015 to 2016, coincided with the hottest year on record. It’s not yet clear how strong the 2023 El Niño will be. Right now, forecasters give it a 56% chance of developing into a strong El Niño, and an 84% chance of topping “moderate” strength. “The onset of El Niño has implications for placing 2023 in the running for warmest year on record when combined with climate-warming background,” said University of Georgia meteorology professor Marshall Shepherd. The highest chances for a hot summer are in the southwestern U.S., where Usually, an El Niño mutes hurricane activity in the Atlantic, giving relief to coastal areas in states from Texas to New England, Central America and the Caribbean, weary from recent record busy years. But this time, forecasters don’t see that happening, because of Hurricanes strengthen and grow when they travel over warm seawater, and the tropical regions of the Atlantic Ocean...

The cold Humboldt Current of the Pacific Ocean flows toward the equator along the coasts of Ecuador and Peru in South America. When the current approaches the equator, the westward-flowing trade winds cause nutrient-rich cold water along the coast to rise from deeper depths to more shallow ones. This upwelling of water has economic repercussions. Fishing, especially for anchovies, is a major local industry. Every year during the months of December and January, a weak, warm countercurrent replaces the normally cold coastal waters. Without the upwelling of nutrients from below to feed the fish, fishing comes to a standstill. Fishers in this region have known the phenomenon for hundreds of years. In fact, this is the time of year they traditionally set aside to tend to their equipment and await the return of cold water. The residents of the region have given this phenomenon the name of El Niño, which is Spanish for "the child," because it occurs at about the time of the celebration of birth of the Christ child. While the warm-water countercurrent usually lasts for two months or less, there are occasions when the disruption to the normal flow lasts for many months. In these situations, water temperatures are raised not just along the coast, but for thousands of kilometers offshore. Over the last few decades, the term El Niño has come to be used to describe these exceptionally strong episodes and not the annual event. During the past 60 years, at least ten El Niños have been ob...
