The Statistical Theory of Stationary Turbulence
… ranges dominated, respectively, by a downward enstrophy cascade and an upward energy cascade. Finally, we contribute to the theory of wavelet transforms by demonstrating the existence of a Gibbs phenomenon for the continuous wavelet transform; the overshoot of the reconstructed function, at …

Exact coherent structures and non-universality in the direct cascade in two-dimensional turbulence
… often characterized by the presence of various cascades, which transport various quantities across length scales. This dissertation focuses on turbulence confined in two-dimensions, which has two cascades: an inverse (energy) cascade that moves energy towards increasingly larger scales, and a …

Experiments in turbulent soap-film flows: Marangoni shocks, frictional drag, and energy spectra
… theoretically possible in two dimensions: the ``enstrophy cascade,'' for which the spectral exponent $\alpha=3$, and the ``inverse energy cascade,'' for which the spectral exponent $\alpha=5/3$. We find that the functional relation between the frictional drag $f$ and the Reynolds number Re …

Eddy forcing of the mean circulation in the western North Atlantic
… that the strength of the eddy transfer in the enstrophy cascade is comparable to the source terms in the mean enstrophy balance. The Austauch coefficient for potential vorticity mixing is estimated to be 0(107cm2/sec). An order of magnitude estimate of the enstrophy dissipation due only to the …
