Gravitational tidal waves in Titan's upper atmosphere

Résumé

Tidal waves driven by Titan's orbital eccentricity through the time-dependent component of Saturn's gravitational potential attain nonlinear, saturation amplitudes ( |T|>10 K, |u|>20 ms, and |w|>5 cms) in the upper atmosphere (=>500 km) due to the approximate exponential growth as the inverse square root of pressure. The gravitational tides, with vertical wavelengths of ˜100-150 km above 500 km altitude, carry energy fluxes sufficient in magnitude to affect the energy balance of the upper atmosphere with heating rates =>10 ergcms in the altitude range of 500-900 km.
