Southern Oscillation Index (“SOI”) Index de l’Oscillation Australe

28 Nov 2004 by group

A measure of the difference in sea level pressure between the western (e.g., Darwin, Australia) and central/eastern (e.g., Tahiti) equatorial Pacific, representative of the east-west changes in atmospheric circulation associated with the El Nino/Southern Oscillation phenomenon. Term was introduced by Sir Gilbert Walker (Walker and Bliss, 1932). More information on the SOI can be found here.

Mesure de la différence de pression atmosphérique au niveau de la mer, entre l’Ouest (ex. Darwin, Australie) et le centre/Est de la région Pacifique équatoriale. Cet index est représentatif des changements Est-/Ouest dans la circulation atmosphérique associés avec le phénomene d’El Niño-Oscillation Australe. Ce terme a été introduit par Sir Gabriel Walker (Walker and Bliss, 1932). Plus d’infos sur cet Index peuvent etre trouvées ici (en anglais).
