Unstable periodic motion in turbulent flows [PDF]
Recently found unstable time-periodic solutions to the incompressible Navier-Stokes equation are reviewed to discuss their relevance to plane Couette turbulence and isotropic turbulence.

Abstract An open boundary setup is presented in which a high‐resolution (high‐res) large eddy simulation (LES) is one‐way nested in a low‐resolution (low‐res) LES. The high‐res nested LES is compared to the periodic LES from Savazzi et al. (2023, https://doi.org/10.1175/jas‐d‐23‐0098.1).

Multiscale turbulence in stellarators
We present the first gyrokinetic simulations of multiscale turbulence in a stellarator, using the magnetic geometry of Wendelstein 7-X (W7-X) and experimentally relevant parameters. A broad range of scenarios is explored, including regimes where electron-

Part I of this two-part series compared two theories for the radial distribution function (RDF), a statistical measure of the clustering of inertial particles in isotropic turbulence. In Part II, we will contrast three theoretical models for the relative

Microclimf: Fast modelling of microclimate across real landscapes in R
Abstract Many ecological studies require climate data, but readily available datasets are poor surrogates for the conditions that organisms experience in nature. Understanding the climatic conditions experienced by organisms requires modelling microclimate rather than relying on coarse, station‐based climate data.

Internal Lee Waves Control Deep Ocean Turbulent Mixing in the Antarctic Circumpolar Current at 50°E
Abstract Full‐depth (Surface‐to‐bottom) turbulent kinetic energy dissipation (TKED) observed with fast‐response thermistors across the Antarctic Circumpolar Current (ACC) at 50° $\mathit{{}^{\circ}}$E is compared with the energy flux of bottom‐generated internal waves estimated with high‐resolution multibeam bathymetry.

Abstract Small‐scale turbulence above 10 km is investigated using observations from two recent airborne field campaigns: the Asian Summer Monsoon Chemical & Climate Impact Project (ACCLIP) and the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS). Turbulence is enhanced by factors of 2–24 inside clouds, within 100 km of active deep convection,

Abstract Accurate simulation of near‐surface wind speed is crucial for applications in renewable energy, dust emission, and air quality modeling. However, the Weather Research and Forecasting (WRF) model systematically over‐estimates 10 m wind speed due to simplified representations of surface roughness and momentum exchange.

Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail
Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.
