Time variation of Jupiter's internal magnetic field consistent with zonal wind advection

Bolton, S. J.; Connerney, J. E. P.; Cao, H. +3 more

Determination of the time dependency (secular variation) of a planet's magnetic field provides a window into understanding the dynamo responsible for generating its field. However, of the six Solar System planets with active dynamos, secular variation has been firmly established only for Earth. Here, we compare magnetic field observations of Jupit…
