Abstract Southern Oscillation indices (differences in sea level atmospheric pressure between Easter Island and Darwin, Australia, and between Juan Fernandez Island and Darwin) were treated so as to emphasize interannual changes and considered for monitoring unusual equatorial Pacific ocean-atmosphere developments and certain of their consequences (e.g., El Nino invasions). It now appears that their trends can be used to predict activity of El Nino intensity several months in advance. 

Relationship between the southern oscillation/El Nino and rainfall in some tropical and midlatitude regions

Association of ENSO (El Nino/southern oscillation) events with annual rainfalls in S. America, Africa, India, Australia and New Zealand was found to be poor except for India and Victoria. For these

Predicting and Observing El Ni�o

In October 1974 the occurrence of a weak El Ni�o event was predicted for early 1975 on the basis of the southern oscillation index and an expedition was organized to study its occurrence and its development with time during two cruises in the waters off Peru and Ecuador.

El Niño: A Destructive Oceanographic Phenomenon

The Peru Current System, one of the most productive marine systems known, is characterized by abundant upwelling, enrichment of surface waters with nutrients, diverse plankton communities, and vast

Impact of El Niño / Southern Oscillation on Low-flows in South Georgia, USA

We investigated the impact of El Niño and La Niña climate patterns on the low flows of seven streams in south Georgia. Four stations were located in heavily irrigated areas of southwestern Georgia,

Differences in Atmospheric Circulation between the Development of Weak and Strong Warm Events in the Southern Oscillation

Abstract In this study temporal and spatial aspects of El Nino (warm event) development are explored by comparing composite sequences of sea level pressure (SLP), surface wind, and sea surface

Atmospheric Carbon Dioxide, the Southern Oscillation, and the Weak 1975 El Ni�o

The observed rate of change of the atmospheric carbon dioxide concentration at the South Pole, Fanning Island, Hawaii, and ocean weather station P correlates with an index of the southern oscillation

Long term variations in western tropical Pacific cyclogenesis associated with the Southern Oscillation

THE ‘Southern Oscillation’, as statistically defined by Sir Gilbert Walker, is the barometrically recorded exchange of air mass in tropical latitudes around the complete circumference of the

Quantification of El Niño Southern Oscillation impact on precipitation and streamflows for improved management of water resources in Alabama

There is increased pressure on the water resources of the southeastern United States due to the rapidly growing population of the region. This pressure is further exacerbated by the severe seasonal

Zonal Winds in the Central Equatorial Pacific and El Ni�o

Easterly trade winds from near-equatorial islands in the central Pacific weakened before each El Ni �o between 1950 and 1978, except for the 1963 El Ni�o, through a series of strong westerly wind bursts lasting 1 to 3 weeks.

The Southern Oscillation, environmental anomalies, and mortality of two Southern African seabirds

Mass mortalities and breeding failures of seabirds in the Pacific Ocean have been directly or indirectly linked to local manifestations of the Southern Oscillation. Similar seabird mortalities have
