Nonlinear emission mechanism for continuum radiation in Jupiter's magnetosphere

The. question of how continuum radiation trapped in Jupiter's magnetosphere might be generated is considered. It is shown that the efficiency of the l inear conversion is not sufficient to account for the observed intensity of the emission. We discuss nonlinear processes that can more easily provide the required conversion efficiency. The field strengths of upper hybrid wav es required to generate the fundamental harmonic emissions are similar to0. 5 divided by 4 mV m(-1). Comparison of the results of the discussed model w ith electric fields reported in the Jovian magnetosphere shows that the mod el adequately explains the generation of continuum radiation trapped in the planetary cavity.
