Turbulence in Geophysics

Fluid in Geophysics including atmosphere and ocean, compared with the normal fluid in Hydrodynamics, its properties, such as density, pressure, temperature and velocity, all change along with altitude. That is to say, fluid in Geophysics is stratified. Therefore, the characteristics of its turbulence at different stratifications will not be the same, either. Some special characteristics, as well as some common ones, will be discussed with nonlinear dynamic methods in this paper. The main problems, such as stratification, non-characteristic scale, scaling invariance and hierarchical structure, may also give suggestions to the research of air turbulence on fire and ventilation.
