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 …

In recent decades, great progress has been made in our understanding of zonal jets across
many subjects-atmospheric science, oceanography, planetary science, geophysical fluid …

We study the role of noise on the nature of the transition to collective motion in dry active
matter. Starting from field theories that predict a continuous transition at the deterministic …

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 …

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

In stochastic systems with weak noise, the logarithm of the stationary distribution becomes
proportional to a large deviation rate function called the quasi-potential. The quasi-potential …

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 …

The perspective of statistical state dynamics (SSD) has recently been applied to the study of
mechanisms underlying turbulence in a variety of physical systems. An SSD is a dynamical …

The Cassini mission unveiled the intense and diverse activity in Saturn's atmosphere:
banded jets, waves, vortices, equatorial oscillations. To set the path towards a better …
