El Niño - National Geographic Society
Dec 9, 2024 · Scientists use the Oceanic Nino Index (ONI) to measure deviations from normal sea-surface temperatures. El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons.
El Nino has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America. El Niño events occur irregularly at two- to seven-year intervals.
What You Need to Know about El Niño - National Geographic …
Oct 26, 2015 · El Niño is the “warm phase” of the El Niño-Southern Oscillation (ENSO). The cool phase, La Niña, is characterized by unusually cool ocean surface currents. El Niño and La Niña can be thought of as the ocean part of ENSO, while the Southern Oscillation can be thought of as the atmospheric part of the phenomenon. When is El Niño going ...
La Niña - Education | National Geographic Society
Dec 9, 2024 · La Niña is considered to be the counterpart to El Niño, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean. Together, La Niña and El Niño are the "cold" (La Niña) and "warm" (El Niño) phases of the El Nino-Southern Oscillation (ENSO).
During El Niño, a weather phenomenon that typically occurs every three to seven years, the Pacific Ocean’s climate changes dramatically. The transition zone between warm surface water and cold deep water deepens.

Jet Stream - National Geographic Society
Oct 19, 2023 · Jet streams are currents of air high above Earth. They move eastward at altitudes of about eight to 15 kilometers (five to nine miles). They form where large temperature differences exist in the atmosphere. An air current is a flowing movement of air within a larger body of air. Air currents flow in the atmosphere, the layers of air surrounding the planet
Ocean Gyre - Education | National Geographic Society
Dec 9, 2024 · An ocean gyre is a large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation.. The movement of the world’s major ocean gyres helps drive the “ ocean conveyor belt.”The ocean conveyor belt circulates ocean water around the entire planet.Also known as thermohaline circulation, the ocean conveyor belt is essential for …
