Description du sujet de thèse

This PhD thesis focuses on the physics of turbulence and its application to environmental systems, specifically air-sea interactions in the ocean. The primary objective is to develop a consistent and well-calibrated mixed-layer-wave parameterization to capture turbulent kinetic energy (TKE) and dissipation processes driven by waves in the ocean. The thesis involves numerical simulations of various atmospheric and oceanic conditions using large eddy simulations (LES), followed by parameter calibration using advanced statistical methods. The goal is to improve our understanding of wave-driven turbulence processes, which are crucial for accurate climate modeling.

An engineering degree and/or Master's degree in physical oceanography, meteorology, climate science or geophysical fluid mechanics is required. The position requires good oral and written communication skills (French and English required) to present at conferences and write articles for scientific journals. We're looking for a young researcher with a strong sense of commitment, curiosity, autonomy and motivation to develop skills in ocean physics. In addition, the candidate must be able to work as part of a team on multidisciplinary projects.

Contexte de travail

The Institut des Géosciences de l'Environnement (IGE) is a public research laboratory under the auspices of the CNRS, the IRD, the Université Grenoble Alpes (UGA) and Grenoble-INP, working on climate change and the anthropisation of our planet in the polar and mountain regions and the intertropical zone, regions that are particularly sensitive and have major societal issues at stake. The average number of staff in the laboratory is around 330, including 190 permanent members (researchers, teacher-researchers, engineers, technicians and administrative staff) and around 140 PhD students, post-docs and staff on fixed-term contracts. Every year, welcomes around 120 scientific interns and visitors. The IGE is housed in four buildings on the Grenoble university campus (glaciology building, OSUG-B, Maison Climat Planète and INRAE-Grenoble Saint Martin d'Hères). The person recruited will work as part of the MEOM team at the IGE and the Institut d'Alembert - Sorbonne Université will be under the responsibility of Julien Lesommer, Bruno Deremble and Stéphane Popinet.
