Growth of small localized perturbations in Surface Quasi-Geostrophic turbulence
V. J. Valadão, M. Cencini, F. De Lillo +2
The butterfly effect, namely the amplification of an initially localized infinitesimal perturbation, is a fundamental hallmark of chaotic systems. While this phenomenon is well und…

Spectrum correction in Ekman-Navier-Stokes turbulence
V. J. Valadão, G. Boffetta, F. De Lillo +2
The presence of a linear friction drag affects significantly the dynamics of turbulent flows in two-dimensions. At small scales, it induces a correction to the slope of the energy…
