Modulus of the horizontal components (ξ_θ and ξ_ϕ) of the displacement vector versus θ/π at some radial meshpoints in the stellar surface region, including the convective shell, for the (100) g-mode with corresponding to 1.033 cpd in the inertial frame. The upper two panels depict the forced solution (with a jump), the lower panels the corresponding free solution with a short wavelength disturbance near θ_c and a tiny spike. The arrow indicates the critical (co)latitude θ_c.
