Unifying Observations, Simulations, and Theory for Drizzle Size Distribution Tails
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract The onset and rate of drizzle remain open problems in atmospheric physics. This study brings together theory, simulations, and observations to analyze the emergence of power‐law tails in droplet size distributions as a signature of a dynamic steady state with coalescence growth balanced by sedimentation removal.

Magnetically Assisted Vorticity Production in Decaying Acoustic Turbulence
The Astrophysical JournalWe study vorticity production in isothermal, subsonic, acoustic (nonvortical), and decaying turbulence due to the presence of magnetic fields. Using three-dimensional numerical simulations, we find that the resulting kinetic energy cascade follows the ...

Phenomenology of hydromagnetic turbulence in a uniformly expanding medium [PDF]
, 1996 A simple phenomenology is developed for the decay and transport of turbulence in a constant-speed, uniformly expanding medium. The fluctuations are assumed to be locally incompressible, and either of the hydrodynamic or non-Alfvénic magnetohydrodynamic ...

Spatial Fluctuations of Optical Turbulence Strength in a Laboratory Turbulence Simulator
PhotonicsControlled turbulence simulators in the laboratory have been extensively employed to investigate turbulence effects on light propagation in the atmosphere, driven by some advanced optical engineering such as remote sensing, energy-delivery systems, and ...

Quantifying finite range plasma turbulence [PDF]
Turbulence is a highly non-linear process ubiquitous in Nature. The nonlinearity is responsible for the coupling of many degrees of freedom leading to an unpredictable dynamical evolution of a turbulent system.

Results in PhysicsBased on the unified theory of coherence-polarization, we utilize the extended Huygens-Fresnel principle to derive analytical expressions for the average intensity distribution of a radially polarized anomalous vortex beam (RPAVB) propagating through non-

A study of magnetic fluctuations and their anomalous scaling in the solar wind: the Ulysses fast-latitude scan [PDF]
Nonlinear Processes in Geophysics, 2001 The solar wind is a highly turbulent and intermittent medium at frequencies between 10-4 and 10-1 Hz. Power spectra are used to look at fluctuations in the components of the magnetic field at high frequencies over a wide range of latitudes.
