Basin-wide sea level coherency in the tropical Indian Ocean driven by Madden–Julian Oscillation

The intraseasonal barotropic response of the ocean has been assumed to be negligible in tropical regions. We show that boreal winter MJOs, aided by ocean stratification, trigger a significant basin-wide barotropic sea level response in the tropical Indian Ocean at intraseasonal time scales.
