<jats:p>This article explores a possible relationship between <jats:italic>S</jats:italic> bursts and trapped Alfvén waves in Jupiter's upper ionosphere. Eigenmodes of inertial Alfvén waves in Jupiter's ionosphere are predicted to have frequencies (∼20 Hz) that match the repetition frequency of <jats:italic>S</jats:italic> bursts and the two phenomena are colocated, suggesting such an association is possible. Electron acceleration or modulation may provide the physical mechanism that transfers energy from the Alfvén wave to the <jats:italic>S</jats:italic> burst. Inertial Alfvén waves are known to accelerate electrons with fluxes that are modulated at Alfvén wave eigenmode frequencies. The modulated electron fluxes, in turn, may generate or modulate the generation of the <jats:italic>S</jats:italic> burst emissions. The exact growth mechanism has not been identified, but we put forth and discuss two possibilities, an anti‐Jovian electron beam or a ring distribution created from impulsive acceleration and mirroring.
