Diversity of strong negative Indian Ocean dipole events since 1980: characteristics and causes
In this study, the diverse features of four strongest negative Indian Ocean dipole (nIOD) (1996, 1998, 2010 and 2016) since 1980 are quantitatively examined. The contributions of air-sea feedback to La Niña-relat...
