Planetary and Inertia-Gravity Waves in a Mid-latitude Channel on a Sphere

Abstract

Having examined in the previous chapter the relationship between waves in an equatorial channel on the $\beta$-plane and on a sphere it is only natural to do the same for a mid-latitude channel. Though mid-latitude waves do not include a unique wave such as the equatorial mixed mode it is still unclear whether or how the inclusion of several latitude-dependent terms associated with the spherical geometry will modify the planar solution derived in Chap. 2 in which only the Coriolis frequency, f(y), was assumed to vary with latitude.
