Figure 7
Wave rays predicted by the buoyancy term of Eq. (8) overlain with near-inertial kinetic energy in the background shading. Curves in red, black, and white show those generated by Krosa, Tapah, and Mitag, respectively. The selected paths are examined for frequencies of \(\omega=1.01f_e,\boldsymbol{ }1.03f_e,\boldsymbol{ }\mathrm{and}\; 1.07f_e\), while horizontal wavenumbers of \(k_H=k_H^M\) and \(k_H=k_H^C\) shown by dashed and solid curves, respectively. As an example, numbers of \(\omega\) and \(k_H\) (subscript) are shown for the curves of Krosa. Note that wave kinetic energy in background is WKB-scaled.
