Some of the dynamical aspects of baroclinic waves of intermediate wavelengths are investigated. A westerly jet, centred at 4S[degrees]N is considered. The flow is initially perturbed by a small-amplitude disturbance, having a zonal scale of 4000 km. This is the wavelength of the most unstable wave as determined by linear model integrations. Firstly, the primitive equations are solved over one life-cycle of the wave of maximum instability. It is found that intermediate wavelengths amplify through a dominating baroc1inic mechanism. The main sources of the eddy energy are the static stability component and zonal component of APE [Pearce (1978)]. It is therefore concluded that Pearce's theory of atmospheric energetics is a comprehensive formulation describing fully the two fundamental roles of eddies; namely the upward and poleward heat transfer.
