Excitation of gravity modes in the parameter space of the tidal wind system

Mostrar todas las versiones(3)

Perturbing the Navier-Stokes equation in the ionospheric F-region, the dispersion relation and the unstable regions in wavenumber space are derived as a function of two control parameters, the colatitude θ and the slow time evolution for tidal modes τ. Our results satisfy the internal gravity wave (...
