Abstract
A form of the evolution equation for the dissipation showing the effects of rotation is derived directly from the Navier–Stokes equations. Rotation affects the dissipation if the flow is inhomogeneous or compressible. This is due to the fact that pressure scales with inverse Rossby number and certain pressure correlations usually neglected have to be retained when Re Ro≊1. The term reflecting the effects of rotation on the dissipation is a volume integral of the two‐point velocity correlation similar in structure to the ‘‘rapid‐pressure’’ correlation appearing in the second‐moment equations. Some of its properties are indicated.Keywords
