Data analysis of Jupiter's synchrotron radio emission demonstrated that the Jovian radiation zones exhibit important temporal variability on different time scales. With the limited in-situ data obtained with spacecraft, much of our understanding of the energetic electrons dynamics has first increased through the analysis of radio observations, then by the development of radiation belts models. In this paper, we present model results that identify the role of various physical mechanisms in explaining the distribution of high-energy electrons trapped in Jupiter's inner radiation belts. Using a theory diffusion model and comparing to the observed features in Jupiter's synchrotron emission, we have investigated the long- and short-term variations of Jupiter's electron radiation belts. Mechanisms linked to solar activity and potentially responsible for temporal changes in the Jovian decimetric emission will be discussed, as well specific implications on the importance of phenomena taking place in the inner magnetosphere.
