La Niña is considered to be the cool phase of the El Niño-Southern Oscillation (ENSO) and is characterized by lower-than-average sea-surface temperatures, with anomalies of at least -0.5 degrees ...
A weak La Niña is favored to develop. NOAA says there is a 59% chance the criteria for La Niña conditions will be met by the end of January 2025.
La Niña conditions typically span about 9 to 12 months, but can go as long as two years, according to the National Oceanic Atmospheric Administration. Ullrich said the current episode is a record ...
The El Niño–Southern Oscillation is a single climate phenomenon that quasi-periodically fluctuates between three phases: Neutral, La Niña or El Niño. [12] La Niña and El Niño are opposite phases which require certain changes to take place in both the ocean and the atmosphere before an event is declared. [12]
Across Alaska, El Niño events do not have a correlation towards dry or wet conditions; however, La Niña events lead to drier than normal conditions.During El Niño events, increased precipitation is expected in Southern California, Arizona, and New Mexico due to a more southerly, zonal, storm track over the Southwest, leading to increased winter snowpack, but a more subdued summer monsoon ...
Jason-3 is a satellite altimeter created by a partnership of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Aeronautic and Space Administration (), and is an international cooperative mission in which National Oceanic and Atmospheric Administration (NOAA) is partnering with the Centre National d'Études Spatiales (CNES, French space agency).
La Niña conditions typically span about 9 to 12 months but can go as long as two years, according to NOAA. “There’s a lot of things that come into play with that,” Cullen said on why La ...
[8] [9] [10] Despite the La Niña background to the Pacific Climate, four El Niño events occurred during 2002–03, 2004–05, 2006–07, and 2009–10. The first three of these events were weaker, while the 2009-10 event was a strong El Niño, but had shorter effects than the 1997–98 event.
