Two types of hydroclimatic conditions exist in the South-Western Pacifie: - one is characterized by the seasonal movement during the year from 10°S to 10°N of the Intertropical Convergence Zone of the winds, which induces the wet season and a surface salinity minimum. The surface circulation is made up of two current systems separated by the 160°W meridian. West of 180°, the maximum ofheat content spreads from 10°S to 10°N. - the other is characterized by the presence at the equator of the Intertropical Convergence Zone of the winds for severa! months. Due to heavy rainfall, the surface salinity minimum is found on the equator whereas, south of 1 oos, a maximum is noticed. Only one current system exists from 160°E to 140°W. The beat content maximum moves from the Western Pacifie to the Central Pacifie. These conditions usually prevail6 months after an El Nino phenomenon. Oceanol. Acta, 1981, 4, 1, 57-62. Deux sortes de conditions hydroclimatiques dans le Pacifique tropical Sud-Ouest. Il y a deux sortes de conditions hydroclimatiques dans le Pacifique tropical Sud-Ouest : - l'une est caractérisée par l'oscillation saisonnière de la zone intertropicale de convergence des vents de lOoS à 10°N, qui amène la saison des pluies et provoque l'apparition d'un minimum de salinité de surface. La circulation de surface est constituée de deux systèmes de courants séparés par le méridien 160°W. A l'ouest de 180°, le maxünum de co
