Solar forced Dansgaard-Oeschger events and their phase relation with solar proxies
H. Braun, P. Ditlevsen, D. R. Chialvo
North Atlantic climate during glacial times was characterized by large-amplitude switchings, the Dansgaard-Oeschger (DO) events, with an apparent tendency to recur preferably in mu…
Scaling and the prediction of energy spectra in decaying hydrodynamic turbulence
P. D. Ditlevsen, M. H. Jensen, P. Olesen
Few rigorous results are derived for fully developed turbulence. By applying the scaling properties of the Navier-Stokes equation we have derived a relation for the energy spectrum…
A note on dissipation in helical turbulence
P. D. Ditlevsen, P. Giuliani
In helical turbulence a linear cascade of helicity accompanying the energy cascade has been suggested. Since energy and helicity have different dimensionality we suggest the existe…
Temporal intermittency and cascades in shell models of turbulence
P. D. Ditlevsen
The 2d and 3d like Gletzer, Okhitani and Yamada (GOY) shell models are examined. The 2d like model shows a transition from statistical quasi-equilibrium to cascade of enstrophy as…
Cascades and statistical equilibrium in shell models of turbulence
P. D. Ditlevsen, I. A. Mogensen
We study the GOY shell model simulating the cascade processes of turbulent flow. The model has two inviscid invariants governing the dynamical behavior. Depending on the choice of…
