dc.description.abstractThe impacts of explosive volcanism on the densely populated Indian Ocean (IO) region remain elusive. Dedicated sensitivity experiments indicate that tropical volcanic eruptions induce a stronger surface cooling over Africa than of ocean, promoting westerlies in the equatorial IO. These westerlies drive a subsurface response reminiscent to that of a negative IO Dipole (IOD) during autumn in the year of eruption. The eruption also drives an enhanced cooling over the northwestern IO as a direct response to climatological cloud cover distribution. The resulting anomalous zonal sea surface temperature gradient contributes to enhance equatorial westerly anomalies in summer. The response is sensitive to the IO preconditioning, being larger when the system is favorable to a positive IOD development. Volcanic eruptions also induce a subsurface IOD-like response in the multimodel database from the Coupled Model Intercomparison Project Phase 5 as well as a primary productivity decrease in the eastern IO
