  abstract = {{C}hanges in sea level may be attributed either to barotropic (involving the entire water column) or baroclinic processes (governed by stratification). {I}t has been widely accepted that barotropic sea level changes in the tropics are insignificant at intraseasonal time scales (periods of 30-80 days). {B}ased on bottom pressure records, we present evidence for significant basin-wide barotropic sea level variability in the tropical {I}ndian {O}cean during {D}ecember-{A}pril with standard deviations amounting to similar to 30-60% of the standard deviation in total intraseasonal sea level variability. {T}he origin of this variability is linked to a small patch of wind over the {E}astern {I}ndian {O}cean, associated with boreal winter {M}adden-{J}ulian {O}scillations ({MJO}). {T}hese large fluctuations are likely to play a prominent role in the intraseasonal sea level and mass budgets. {B}ecause of their much faster propagation than baroclinic processes, they allow the basin to adjust to climatic perturbations much more rapidly than was previously thought.},
