For example, a , for instance, may dissipate close to the surface due to Friction with the land mass, and at higher levels due to Radiative Cooling . In Computational Physics , a numerical dissipation is also known as "artificial dissipation" or "artificial diffusion" or "numerical diffusion". They all mean this: when the pure advection equation--which, by definition, is free of dissipation--is solved by a numerical approximation method that reduces the amplitude and changes the shape of the initial wave in a way analogous to a diffusional process, the method is said to contain 'dissipation'. A formal, mathematical definition of dissipation, as commonly used in the mathematical study of Measure-preserving Dynamical System s, is given in the article '' Wandering Set ''. |
