Abstract: The horizontal wavenumber spectra of wind and temperature in the upper troposphere and lower stratosphere display a narrow k?3 range at scales on the order of 1000 km and a broad k?5/3 range at mesoscales on the order of ...

Abstract: The author shows that the horizontal two-point correlations of vertical vorticity and the associated vorticity wavenumber spectrum can be constructed from previously measured velocity structure functions in the upper ...

Abstract: new formulation of the spectral energy budget of kinetic and available potential energies of the atmosphere is derived, with spherical harmonics as base functions. Compared to previous formulations, there are three main ...

Abstract: AbstractRecently, it has been discussed whether the mesoscale energy spectra in the upper troposphere and lower stratosphere are generated by weakly or strongly nonlinear dynamics. A necessary condition for weak nonlinearity ...

Abstract: Several existing sets of smaller-scale ocean and atmospheric data appear to display Kolmogorov?Obukov?Corrsin inertial ranges in horizontal spectra for length scales up to at least a few hundred meters. It is argued here ...
