Intermittent turbulence is key for understanding the stochastic nonlinear dynamics of space,
astrophysical, and laboratory plasmas. We review the theory of deterministic and stochastic …

Turbulence is ubiquitous in the insterstellar medium and plays a major role in several
processes such as the formation of dense structures and stars, the stability of molecular …

The spatiotemporal dynamics of vorticity and magnetic field in the region of a photospheric
vortex at a supergranular junction of the quiet Sun is studied, using Hinode's continuum …

The Schwabe cycle of solar activity exhibits modulations and frequency fluctuations on slow
timescales of centuries and millennia. Plausible physical explanations for the cause of these …

The dynamics of the Earth's atmosphere is characterized by a wide spectrum of oscillations,
ranging from hourly to interdecadal and beyond. The low-frequency component of the …

We report observational evidence of Lagrangian chaotic saddles in plasmas, given by the
intersections of finite-time unstable and stable manifolds, using an≈ 22 h sequence of …

The relation between current sheets, turbulence, and magnetic reconnections at the leading
edge of an interplanetary coronal mass ejection detected by four Cluster spacecraft on 2005 …

The study of tropical tropospheric disturbances has led to important challenges from both
observational and theoretical points of view. In particular, the observed wavenumber …

The long-term solar cycle variability and Grand solar minima remain open questions from a
theoretical point of view. Recently, a growing basis of evidence points out to the role of the …

We present a theoretical and numerical study of Fourier-space triad phase dynamics in the
one-dimensional stochastically forced Burgers equation at Reynolds number. We …
