Following the El Nino event in 1997 – 1998, the Pacific Marine Environmental Laboratory attributes the first large-scale coral bleaching event to the warming waters. [169] Most critically, global mass bleaching events were recorded in 1997-98 and 2015–16, when around 75-99% losses of live coral were registered across the world.
A major key to shaping weather patterns worldwide is found in the tropical Pacific Ocean, far from any mainland. Known as the El Niño-Southern Oscillation (ENSO), this climate phenomenon is the ...
La Niña is considered 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 ...
Palm Beach Post weather reporter Kimberly Miller explains the effects of El Niño and La Niña on South Florida weather.
An El Niño episode is characterised by a breakdown of this water and air cycle, resulting in relatively warm water and moist air in the eastern Pacific. The Walker circulation , also known as the Walker cell , is a conceptual model of the air flow in the tropics in the lower atmosphere ( troposphere ).
El Niño is a natural climate event caused by the Southern Oscillation, popularly known as El Niño or also in meteorological circles as El Niño-Southern Oscillation or ENSO, [6] through which global warming of the eastern equatorial Pacific Ocean results in the development of unusually warm waters between the coast of South America and the ...
El Niño finally lost its grip on global weather in June, but La Niña’s arrival was delayed repeatedly, leaving an extended period of neutral conditions in place through the summer and fall.
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 ...
