• Resumen

  • We present an exact solution to the governing equations for some azimuthally propagating flows with stratification in the spherical coordinates. Using the short-wavelength perturbation method in the spirit of Constantin, Germain (J Geophys Res Oceans 118:2802-2810, 2013), Henry, Martin (J Diff Equ 266:6788-6808, 2019), Henry, Martin (Arch Rat Mech Anal 233:497-512, 2019), Ionescu-Kruse, Martin (J Math Fluid Mech 20:7-34, 2018), we prove that such flows are linearly stable for a specific choice of the density.
