Thématique(s) de Recherche :
Océans et variations climatiques: variabilité océanique et climatique tropicale, avec un focus sur les océans Pacifique et Indien, et sur les échelles intrasaisonnières à interannuelles. Evénements El Niño et La Niña : mécanismes, et diversité de leurs influences sur le Pacifique Sud, par exemple en terme de précipitations, de niveau de la mer et de production primaire. Impacts du changement climatique. Objectif principal : améliorer leur compréhension, et donc leur prévisibilité.
