Canopy wetness in the Eastern Amazon
...
Canopy wetness is a common condition that influences photosynthesis, the leaching or uptake of solutes, the water status and energy balance of canopies, and the interpretation of eddy covariance and remote sensing data. While often treated as a binary variable, ‘wet’ or ‘dry’, forest canopies are often partially wet, requiring the use of a continuo...
Couche limite turbulente sur paroi rugueuse : étude expérimentale et modélisation
Les écoulements turbulents sur parois rugueuses apparaissent dans de nombreuses situations environnementales ou industrielles, notamment dans l'aéronautique. Par rapport au cas idéal d'une paroi lisse, une augmentation de traînée et du flux de chaleur pariétal, susceptible de dégrader les performances d'un système (aile, machine tournante...), est ...

Spatially evolving cascades in temporal planar jets
Starting from an alternative decomposition of the turbulent field, a multi-dimensional statistical formalism for the description and understanding of turbulence in free-shear flows is proposed and applied to the symmetries of planar temporal jets. The theoretical framework is based on the exact equation for the second-order moment of the two-point ...

Drag distribution in idealized heterogeneous urban environments
Large-eddy simulations of nine idealized heterogeneous urban morphologies with identical building density and frontal area index are used to explore the impact of heterogeneity on urban airflow. The fractal-like urban morphologies were generated with a new open-source Urban Landscape Generator tool (doi:10.5281/zenodo.3747475). The vertical structu...

Electron energization and energy dissipation in microscale electromagnetic environments
...
Particle energization and energy dissipation in electromagnetic environments are longstanding topics of intensive research in space, laboratory, and astrophysical plasmas. One challenge is to understand these conversion processes at smaller and smaller spatial/temporal scales. In this Letter, with very high cadence measurements of particle distribu...
