Abstract
The occurrence characteristics of Jovian multiple quasi‐periodic (QP) bursts are investigated based on Galileo spacecraft observations. Multiple QP bursts recurrently appeared in a group with a planetary spin period of 10 hours. Their appearance was synchronized with the planetary rotation, i.e., they were preferably excited when Jupiter had a particular spin phase angle with respect to the Sun (at a subsolar longitude of System III around 260–320°). We also found that the burst groups were activated during magnetospheric disturbances probably caused by solar wind pressure variations. The rotationally driven polar disturbances accompanying quasi‐periodic particle accelerations and radio wave bursts are discussed as being one of the daily unloading processes of planetary rotational energy.
