Heating of Jupiter's thermosphere by the dissipation of upward propagating acoustic waves

摘要: Abstract Thunderstorms in Jupiter’s atmosphere are likely to be prodigious generators of acoustic waves, as thunderstorms Earth’s atmosphere. Accordingly, we have used a numerical model study the dissipation thermosphere upward propagating waves. Model simulations performed for range wave periods and horizontal wavelengths believed characterize these The possibility that thermospheric waves observed by Galileo Probe might is also investigated. Whereas dissipating gravity can cool upper through effects sensible heat flux divergence, it found mainly Jovian molecular dissipation, Eulerian drift work. Only wave-induced pressure gradient work cools atmosphere, an effect operates at all altitudes. sum heating heights. Acoustic fundamentally different ways. Though amplitudes mechanical energy fluxes poorly constrained calculations suggest locally significant rate, tens hundred Kelvins per day, thereby account high temperatures It unlikely detected were waves; if they were, would heated enormous rates.
