The Blob is an anomalous body having sea surface temperature much above normal, seen here in a graphic of April 2014 by the NOAA.. The Blob is a large mass of relatively warm water in the Pacific Ocean off the coast of North America that was first detected in late 2013 and continued to spread throughout 2014 and 2015.
By early March 2024, pockets of below average Sea Surface Temperature SST Anomalies pierced the surface in the equatorial East Pacific, a clear sign that the El Niño event was in full retreat. [23] Several severe thunderstorms bringing high winds and pea-sized hail hit Los Angeles, California, causing strong flooding in streets. [24]
El Niño is strictly related to water temperatures near the equator in the eastern Pacific Ocean. In April, NOAA issued an El Niño watch, saying there is a 62% chance of the phenomenon developing ...
Weakening sea surface temperature anomalies in the tropical Pacific in early 2023 associated with the end of the La Niña event. The 2020–2023 La Niña event was unusual in that it featured three consecutive years of La Niña conditions (also called a "triple-dip" La Niña) in contrast to the typical 9–12 month cycles of the El Niño–Southern Oscillation (ENSO), [3] though the magnitude ...
During their March 2015 diagnostic discussion, NOAA's CPC and the IRI reported that El Niño conditions had been observed during February 2015, after the above average sea surface temperatures had become weakly coupled with the tropical atmosphere. [22] [23] By January 2015, westerly wind burst activity picked up again.
where F is the variance of the white noise forcing and w is the frequency, an implication of this equation is that at short time scales (w>>λ) the variance of the ocean temperature increase with the square of the period while at longer timescales(w<<λ, ~150 months) the damping process dominates and limits sea surface temperature anomalies so ...
In the United States, an El Niño is declared when the Climate Prediction Center, which monitors the sea surface temperatures in the Niño 3.4 region and the tropical Pacific, forecasts that the sea surface temperature will be .5 °C (0.90 °F) above average or more for the next several seasons. [108]
Sea surface temperatures have broken records every day for a year, puzzling scientists. The warm water could significantly affect hurricanes and other weather. 12 months of record ocean heat has ...
