The climate is a forced and dissipative nonlinear system featuring nontrivial dynamics on a
vast range of spatial and temporal scales. The understanding of the climate's structural and …

Understanding inhomogeneous and anisotropic fluid flows requires mathematical and
computational tools that are tailored to such flows and distinct from methods used to …

The atmosphere and ocean are two of the most important components of the climate system,
and fluid dynamics is central to our understanding of both. This book provides a unified and …

Many turbulent flows undergo drastic and abrupt configuration changes with huge impacts.
As a paradigmatic example we study the multistability of jet dynamics in a barotropic beta …

Recent advances in mean-field theory are reviewed and applications to the Sun, late-type
stars, accretion disks, galaxies and the early Universe are discussed. We focus particularly …

Mean-field dynamo theory has important applications in solar physics and galactic
magnetism. We discuss some of the many turbulence effects relevant to the generation of …

Quasilinear theory is often utilized to approximate the dynamics of fluids exhibiting
significant interactions between mean flows and eddies. We present a generalization of …

Zonal flows are well known to arise spontaneously out of turbulence. We show that for
statistically averaged equations of the stochastically forced generalized Hasegawa-Mima …

Emergence and Equilibration of Jets in Beta-Plane Turbulence: Applications of Stochastic
Structural Stability Theory in: Journal of the Atmospheric Sciences Volume 71 Issue 5 (2014) …

We discuss the dynamics of zonal (or unidirectional) jets for barotropic flows forced by
Gaussian stochastic fields with white in time correlation functions. This problem contains the …
