Narrow-band (NB) events in dynamic spectra and their relation with short (S-) bursts are an unresolved enigma of the Jovian decametric emission. This paper is focused on the S/NB-structure with timescales between 0.03 s and 0.3 s. We show that the main S/NB-phenomenology can be reduced to three main ingredients which are: the dispersion delay of the radio emission, the motion of emitting electrons in the parallel electric field of the standing Alfv´en wave, and the shadow effect.
