El Niño and La Niña have perhaps the strongest influence on year-to-year climate variability in Australia. They are a part of a natural cycle known as the El Niño–Southern Oscillation (ENSO) and are associated with a sustained period (many months) of warming (El Niño) or cooling (La Niña) in the central and eastern tropical Pacific.
WMO issues quarterly El Niño/La Niña Updates prepared through a collaborative effort between WMO and the International Research Institute for Climate and Society (IRI) and based on contributions from the leading centres around the world, monitoring and predicting this phenomenon and expert consensus facilitated by WMO and IRI. These updates comprise the observational monitoring of the ...
The El Niño phenomenon can have an impact on weather conditions around the globe, for both the winter and summer periods, as seen in the maps below. The key shows which areas will be wetter, drier, warmer and cooler than normal.
19 de oct. de 2023 · La Niña is a climate pattern that describes the cooling of surface-ocean waters along the tropical west coast of South America. 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 ...
The El Niño phenomenon affects rainfall patterns and temperatures in many parts of the globe, most intensely in the tropics with significant impacts on human health. El Niño 2015-2016 is currently affecting the health of millions of vulnerable people in the Horn of Africa, southern and eastern Africa, South Pacific, Central America and South
El Niño is felt strongly in the tropical eastern Pacific with warmer than average weather. The effects of El Niño often peak during December; it's name "the boy" is thought to have originated as "El Niño de Navidad" centuries ago when Peruvian fishermen named the weather phenomenon after the newborn Christ. What is La Niña?
The El Niño phenomenon is a natural event, frequent in the fire belt of the Pacific Ocean, characterized by intense tectonic activity: volcanic and seismic that add energy to the ocean floor and the atmosphere causing the El Niño tectonic phenomenon. The Earth is made up of geospheres to the solid,... Descripción completa
