Postdoc on Interactions between large structures, gravity waves

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.
