layer; and C D is the bottom drag coefficient. (For specific values, see CPH.) The time-averaged momentum budget is discussed in CPH. The three terms on the right-hand side of (2) must balance. The wind stress is balanced, on the broad scale, by bottom drag as shown in Fig. 12 . However, there are spatial variations in the latter on the jet scale that do not correspond to features in the wind stress; rather, these variations balance the convergence of eddy momentum fluxes (e.g., Held 1975

1. Introduction Chaotic flows in stratified, rotating fluid systems like planetary atmospheres and oceans are often called “turbulent.” However, in such systems there is no such thing as turbulence without waves, a point well brought out in the celebrated paper of Rhines (1975) . One way to appreciate the point is to note that such systems always have background gradients of potential vorticity (PV) and then consider the implications for the momentum and angular momentum budgets. As will be
