Scale invariance, symmetries, fractals and stochastic simulations of atmospheric phenomena.

Abstract

Examines the implications of three observed characteristics of mesoscale circulations. Some recent work in turbulence, physics, and meteorology, that is relevant to systems with extreme variability over a wide range of scales is reviewed. The concepts of scaling, intermittency, and fractals, are briefly introduced to show how they can be used to understand the physics of both homogeneous and intermittent energy cascades in isotropic atmospheres. Finally, it is shown how to construct fractal models.-from Authors
