El Niño and La Niña - National Oceanic and Atmospheric Administration By influencing global temperatures and precipitation, the El Niño Southern Oscillation (ENSO) significantly impacts Earth’s ecosystems and human societies El Niño and La Niña are opposite extremes of the ENSO, which refers to cyclical environmental conditions that occur across the Equatorial Pacific Ocean These changes are due to natural interactions between the ocean and atmosphere
Understanding El Niño - National Oceanic and Atmospheric Administration El Nino has its largest impacts during the winter In the winter, El Niño typically brings milder weather to the northern parts of the United States and wetter conditions across the southern United States The opposite of El Niño is La Niña, the cold phase, which also changes weather worldwide
El Niño Southern Oscillation (ENSO) - National Oceanic and Atmospheric . . . Further research found that El Niño is actually part of a much larger global variation in the atmosphere called ENSO (El Niño Southern Oscillation) The Southern Oscillation describes changes in air pressure patterns in the Southern Pacific Ocean between Tahiti, in the middle of the southern Pacific Ocean, and Darwin, Australia, to the west Normally, lower pressure over Darwin and higher
El Niño and La Niña Explained | Ocean Today Transcript NARRATOR: Warmer or colder than average ocean temperatures in one part of the world can influence weather around the globe - boggles the mind, right? Here’s how it works During normal conditions, trade winds, which blow from east to west, push warm surface waters towards Asia, piling it up in the western Pacific In some years though, the trade winds weaken The warm surface
Forecasting El Niño and La Niña| Ocean Today El Niño and La Niña are periodic weather patterns resulting from interactions between the ocean and the atmosphere in the tropical Pacific Ocean
Data in the Classroom - National Oceanic and Atmospheric Administration With NOAA’s Data in the Classroom, students use historical and real-time NOAA data to explore today’s most pressing environmental issues Each of the five modules addresses research questions, includes stepped levels of engagement, and builds students’ abilities to understand, interpret, and think critically about data Explore the online modules and educator resources below
U. S. Winter Outlook: Wetter South, warmer North This year, El Nino is in place heading into winter for the first time in four years, driving the outlook for warmer-than-average temperatures for the northern tier of the continental United States, according to NOAA’s U S Winter Outlook released today by the Climate Prediction Center — a division of the National Weather Service “These outlooks provide critical guidance on the upcoming
Effects of ENSO in the Pacific - National Oceanic and Atmospheric . . . Normal Conditions Normally, sea surface temperature is about 14°F (8°C) higher in the Western Pacific than the waters off South America This is due to the trade winds blowing from east to west along the equator, allowing the upwelling of cold, nutrient rich water from deeper levels off the northwest coast of South America These s
Spring Outlook: Dry in the West, milder than average in the South and . . . There is a 75% probability that ENSO-neutral conditions — neither El Nino nor La Nina — will return in the February-April 2025 time frame “La Nina’s influence on the Spring Outlook is limited as it weakens entering the spring months,” said Jon Gottschalck, chief of the Operational Prediction Branch, NOAA’s Climate Prediction Center
