New perspectives on superparameterization for geophysical turbulence
This is a research expository paper regarding superparameterization, a class of multi-scale numerical methods designed to cope with the intermittent multi-scale effects of inhomogeneous geophysical turbulence where energy often inverse-cascades from the unresolved scales to the large scales through the effects of waves, jets, vortices, and latent heat release from moist processes. Original as w...
متن کاملRoutes to Dissipation in the Ocean: The 2D/3D Turbulence Conundrum
Turbulence research has reached a mature stage, even though at the most fundamental level turbulence itself remains a mystery. The phenomenology and physical mechanisms of the separate regimes of twoand threedimensional, geostrophic, stratified, gravity-wave, and boundary-layer turbulence are all now fairly completely established. They describe well the nature of geophysical turbulence at vario...
متن کاملQuasi-linear theory of forced rotating sheared turbulence
Rotation and shear flows are an ubiquitous features of many astrophysical and geophysical bodies, playing a crucial role in turbulent transport. To understand the complex dynamics in these systems, we provide a consistent theory of turbulence in the presence of shear and rotation. Starting from a quasi-linear equation for the fluctuating fields, we derive turbulence amplitude and turbulent tran...
متن کاملOn a possible mechanism of anomalous diffusion in geophysical turbulence
The main characteristic features of the geophysical turbulence are differential (so called ,8-effect) rotation and stratification. Each of these phenomena is responsible for a specific type of waves: planetary or Rossby waves and internal gravity waves, respectively. It is well-known that e.g. for the ,8plane turbulence [1] one may have vortex-dominated (Le. close to the 2d turbulence), wave-do...
متن کاملNon-stationary Geophysical Processes, Application to Turbulence and Clouds
In recent years, considerable progress has been achieved in the description of natural variability, largely due to the widespread use of scale-invariant concepts such as fractals and multifractals. In particular, this last concept has been used to clarify the fuzzy notion of ‘inhomogeneity’ by introducing and quantifying the effects of intermittency. In this paper, we present a more comprehensi...
