We propose an excitation mechanism for the recently discovered very slow wavelike structure in the Jovian atmosphere. We regard it as normal mode gravity-wave oscillations of the Jovian atmosphere. Such oscillations are excited through resonance couplings with prograde inertial oscillations of the convective interior having negative energies. The amplitude of a low-frequency oscillation of the Jovian atmosphere can be large only in the equatorial region.
