Abstract
The fundamental equations of motion, and continuity equations for heat and water substance, are basically nonlinear. They contain information concerning atmospheric motion and transport over scales ranging from the largest eddies on the globe down to the very smallest eddies contributing to molecular dissipation. At the present time there is no known mathematical technique for exactly integrating this set of equations. Moreover, feasible observational systems are incapable of resolving or defining all scales of atmospheric motion contributing to the kinetic energy and transport in the atmosphere. Thus, meteorologists have been forced to distinguish between those eddies that are in a sense resolvable, either by observation systems or by some form of finite difference representation of the atmosphere (included are finite element and truncated spectral representations of the atmosphere), and the eddies that are not fully resolved either observationally or computationally.
