On Redistributed Energy Fluxes in Topographic Scattering Problems
نویسنده
چکیده
The scattering of infinitesimal inviscid internal waves at topography redistributes the incoming energy flux in wave number and physical space. This energy flux redistribution describes the scattering process most succinctly. The definitions of the redistributed energy flux in wave number space and in various subspaces are given. All of the incident energy flux is redistributed in wave number space. The total redistributed energy flux in subspaces is only a fraction of the total incident flux and depends on the choice of subspace. These concepts are illustrated with examples from the scattering at an infinite straight slope, random infinitesimal topography, and finite topography in a finite-depth ocean.

The critical role of magnetic helicity in astrophysical large-scale dynamos
The role of magnetic helicity in astrophysical large-scale dynamos is reviewed and compared with cases where there is no energy supply and an initial magnetic field can only decay. In both cases magnetic energy tends to get redistributed to larger scales. Depending on the efficiency of magnetic helicity fluxes, the decay of a helical field can speed up. Likewise, the saturation of a helical dyn...
