<div dir="ltr">The CNRS is inviting applications for a
2-year postdoctoral research position to undertake
high-resolution model analysis to investigate
dynamical processes in the Southern Ocean.<br>
<br>
The post is attached to the Exciting project, which
aims at mapping and unveiling the dynamics of the
tri-dimensional structure of the meridional
overturning circulation in the Southern Ocean. The
successful applicant will investigate the dynamics
associated to cross-frontal exchange and mixing in the
Antarctic Circumpolar Current using a state-of-the art
high-resolution ocean model (NEMO framework).
Cross-frontal exchange and dynamics in the model will
be investigated using Lagrangian particles diagnosis.
The study will build on <span>observation</span>-based
analysis demonstrating that cross-front transport in
the ACC is highly asymmetric. Cross-front exchanges at
<span>ocean surface</span> is localized in the lee of
<span>bathymetric</span> features with more than 75%
of crossing events occurring in regions corresponding
to only 20% of the ACC’s zonal extent. The goal of
this study will be to investigate the vertical
structure of this exchange and its time-<span>variability</span>.
In addition, strong emphasis will be given to the
jet/topography interactions and the dynamics
associated <span>to</span> it (e.g. <span>vertical</span>
propagation of momentum flux, form drag,
stratification, vertical velocities). Strong <span>connexions</span>
between this model-based analysis and
observation-based analysis will be made. We
particularly seek a researcher with an interest in and
talent in ocean model analysis and ability in running
numerical simulations to develop deeper dynamical
understanding of ocean circulation and climate. The
researcher will join a team of scientists at
LOCEAN-IPSL in Paris and will strongly collaborate
with project partners at the National Oceanography
Centre (Jan Zika in Southampton, UK) and LPO (Bruno
Blanke in Brest, France).<br>
