Objective: We propose to study turbulence and mixing in stably stratified fluid.
Chapters cover the system properties of the earth-atmosphere system, the basic meteorological variables, and thermodynamic processes related to atmospheric circulation; the physical basis of the general circulation of the atmosphere, the heat and moisture cycle, the influence of local physical and geographical conditions of atmospheric air movements, and patterns of development of man-made and natural processes in the boundary layer; the basic equations of mechanics of viscous stratified fluid used in the simulation of atmospheric circulation; problems related to the modeling of atmospheric processes of various scales; the development and use of parameterization methods of sub-scale processes; and analysis of numerical methods for reproducing specific physical processes.
Gravity collapse in a two-layer stratified fluid system is adopted to excite the ISWs [24].
The experiments of ISWs force measurement are conducted in a long stratified fluid tank at the PLA University of Science and Technology, which is made of steel frame and glass materials with the dimension of 12 m length, 0.
The principle of generating internal solitons and measuring forces in a stratified fluid tank is shown in Figure 8.
The evolution of long internal waves (IWs) with small amplitudes in a stably stratified fluid is governed approximately by a linear wave equation, with small but cumulative corrections due to weak nonlinearity, dispersion and dissipation, and possibly to a slowly varying background.

This continuously stratified fluid interface is more or less analogous to real situations involving miscible fluids.
The radially stratified fluid behaviour for the case of either or both the cylinders rotating co-currently or counter-currently so also the rigid rotation of cylinders has been verified experimentally and numerically by few authors (Schneyer and Berger, 1971; Joseph et al.
It has been observed from the simulations that the interface radius depends on the rotation ratios of both the cylinders, the properties of the fluids, the interfacial tension and the volume fraction of the stratified fluid phases.
