YSYS PhYSique at the EcoSystems interface

Key words
Root anchoring; Biotic particle dispersion; Soil-plant-atmosphere exchange; Wind-plant interaction; Large Eddy Simulation; Fluid mechanics; Ozone; Landscape; REA

The Physics at the EcoSystems Interface (YSYS) team tackles environmental issues in a specific niche involving atmospheric flow, soil and plant mechanics, and soil-plant-atmosphere exchanges on a wide range of spatial scales, including that of the landscape in particular, which is heterogeneous in essence (from a few meters to several kilometers). These themes fall within the dual context of (i) climate change and extreme events (storms in particular), and (ii) agricultural practices and their agro-environmental consequences (on the dispersion of contaminants and pollutants, for example).

Our main results are balanced around three themes
Turbulent flow and wind-plant interaction
Atmospheric dispersion of particles
Matter and energy exchanges between ecosystems and the atmosphere
