Growth rates of the most unstable waves as functions of kx for linear baroclinic instability about the state of rest,
. High latitude (solid line), midlatitude (long-dashed line), and low latitude (short-dashed line). The Nyquist wavenumber of the coarse grid in the stochastic SP tests is |kx| = 32, and the deformation wavenumber is kd = 50.
