This postdoctorate investigates the question of the influence of large 
structures on small scales and their fluctuations and vice versa in atmospherics dynamics.

In particular, this postdoctorate will consist especially in performing Direct
 Numerical Simulations (DNS) of an idealized geophysical flow in the strongly 
stratified turbulence (SST) regime (i.e. small Froude number and high buoyancy 
Reynolds number) containing large structures called vertically-sheared 
horizontal flow, internal gravity waves and eddies. In addition, he will have to 
apply a new method for extracting large strutures, waves and vortices, developed 
in our team (Lam et.al. atmos 2020 , JFM 2021 & JFM 2023) and calculate the 
velocity increments for each part.  

This post-doctorate is founded by French Agency of Research (ANR) with LASWATEX 
project which aims to better understand and predict large scale / Gravity-Wave / 
micro-turbulence interactions by new theoretical models fed by quantitative data 
provided by numerical simulations. The project is a collaboration between 
theoretician (M2C laboratory at Rouen France) and numericists (LMFA laboratory 
at Ecole Centrale de Lyon France).
