Frequency spectrum of the energy per mass unit dissipated in different regimes (ζ) (continuous red line), and of its viscous and thermal contributions ζvisc (dashed green line) and ζtherm (dashed blue line). The latitude is fixed at θ = 0. In abscissa, the normalized frequency ω = χ/ 2Ω. Top left: A = 1.0 × 10-2; E = 1.0 × 10-2; K = 1.0 × 10-4. Top right: A = 1.0 × 102; E = 1.0 × 10-2; K = 1.0 × 10-4. Bottom left: A = 1.0 × 10-2; E = 1.0 × 10-4; K = 1.0 × 10-2. Bottom right: A = 1.0 × 102; E = 1.0 × 10-4; K = 1.0 × 10-2.
