The Southern Oscillation is the accompanying atmospheric oscillation, which is coupled with the sea temperature change. El Niño is associated with higher than normal air sea level pressure over Indonesia, Australia and across the Indian Ocean to the Atlantic. La Niña has roughly the reverse pattern: high pressure over the central and eastern ...
This El Niño-related drought ended in March, when a monsoon depression became an extratropical low and swept across Australia's interior and on to the south-east in mid-to late March. 1987–88 were weak El Niño years, with 1988–89 featuring a strong La Niña event affecting the southeast half of the country.
The completed TAO array provides in-situ data collection of high quality oceanographic and surface meteorological data for monitoring, forecasting, and understanding of climate swings associated with El Niño and La Nina. In January 2000, the TAO array was renamed the TAO/TRITON array in recognition of the contribution made by the TRITON ...
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 ...
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 ...
El Niños and their opposites, La Niñas, are naturally occurring weather phenomena that usually appear every two to seven years as a function of how the Pacific Ocean interacts with the air above it.
Strong El Niños have recently been observed from 1997 into 1998 and from 2015 into 2016. The increased chance for El Niño comes after La Niña conditions were present for nearly three straight ...
El Niño and La Niña are opposite surface temperature anomalies of the Southern Pacific, which heavily influence the weather on a large scale. In the case of El Niño, warm surface water approaches the coasts of South America which results in blocking the upwelling of nutrient-rich deep water. This has serious impacts on the fish populations.
