Parameter values for modes 1–10 of the LCS model. Values of c_{n} correspond to the N_{b}(z) profile used for the control run. Coefficients Z_{n} are determined from profile (2) with z_{1} = −10 m and z_{2} = −20 m. The quantities α^{−1}_{n0} = c_{n}/β and σ_{n0} = βc_{n} are the equatorial Rossby radii of deformation and equatorial inertial frequencies for each mode, respectively. The quantities 2π/k_{r} and k^{−1}_{i}, defined after (10), are the wavelength and damping scale of a Yanai wave when 2π/σ = 14 days and A = 8.84 × 10^{−4} cm^{2} s^{−3}.
