Plain Language Summary: A marked impact of the stratospheric quasi-biennial oscillation (QBO) on the Madden–Julian Oscillation (MJO) has become evident in recent studies. In this study, we show that the QBO affects the annually phase-locked seasonal migration of the tropical convection from the equatorial Indian Ocean to the Western Pacific in the Austral summer: large-scale convection strengthens and moves eastward more effectively during easterly phase of the QBO (QBO‒E) in austral summers than that during westerly phase of the (QBO‒W).
