The Southern Oscillation is the atmospheric component of El Niño. This component is an oscillation in surface air pressure between the tropical eastern and the western Pacific Ocean waters. The El Niño–Southern Oscillation is a single climate phenomenon that periodically fluctuates between three phases: Neutral, La Niña or El Niño. [ 12]
El Paso expects another scorching summer and warm winter due to La Niña, with a 40% chance 2024 will be the hottest year on record, according to NWS. La Niña is pushing El Niño out. What that ...
During a La Niña, it’s typically wetter and colder in the Pacific Northwest throughout the winter. La Niñas and El Niños can also affect the Pacific hurricane season, which runs from June ...
The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
One of those climate patterns is El Niño and La Niña, a weather phenomenon that occurs in the Pacific Ocean and can affect global weather. Here’s what the two weather patterns mean and how ...
Impact of El Niño and La Niña on North America. The El Niño–Southern Oscillation affects the location of the jet stream, which alters rainfall patterns across the West, Midwest, the Southeast, and throughout the tropics. The shift in the jet stream also leads to shifts in the occurrence of severe weather, and the number of tropical ...
In Texas, La Nina generally means drought. As the ground dries up with lack of rain during a La Nina year, it generates an abundance of heat. North Texas experienced that in the summer of 2023 as ...
El Niño episodes are defined as continuous warming of the central and eastern tropical Pacific Ocean, thus resulting in a decrease in the strength of the Pacific trade winds, and a reduction in rainfall over eastern and northern Australia, particularly in winter and spring. An El Niño event typically begins in autumn and fully forms during ...
