[Met-jobs] Post-doctoral position at CNRM-GAME (Toulouse, France) in atmospheric convection

From francoise guichard <>
Date Fri, 19 Apr 2013 12:52:27 +0200

A 18-month post-doctoral position, funded by the ANR CAVIARS, is
available at CNRM-GAME (CNRS and Météo-France) in Toulouse, France,
for a starting date around July 2013.

Topic: Gust winds and turbulence associated with convection in the Sahel

Applicants must contact Françoise Guichard
(, Dominique Bouniol
( and Fleur Couvreux
( no later than 1 June 2013.

Net salary will range from 2000 to 3000 €/m, depending on experience.



CAVIARS is a 4-year project funded by the Agence Nationale de la
Recherche (ANR) in France. The acronym stands for 'Climate,
Agriculture and Vegetation: Impacts on Aeolian eRosion in the Sahel'
and the project is motivated by the vulnerability of sahelian soils to
wind erosion, which affects soil fertility and productivity
capacities. The Sahel experimented major climatic fluctuations during
the last decades, together with substantial changes in land use.
CAVIARS aims to develop an integrated modelling tool allowing to
specifically study the evolution of wind erosion during these decades,
and its connections with climate and land use change. The project
capitalizes on the AMMA (African Monsoon Multidisciplinary Analysis)
project which provides critical datasets for the study, either for
validation or for input to the simulations. It involves several French
laboratories as well as collaborations with researchers from European


Past studies demonstrated the major contribution of convective gusts
to erosion. Such events occur mainly during short periods and are
poorly represented in the wind fields that are currently used by
simulations of dust emission. The first aim of the postdoc project is
to develop a new formulation of the surface gust winds associated with
convection that is well suited for semi-arid regions such as the
Sahel. The approach will be based on a joint exploitation of in-situ
data and convection-permitting simulations (including simulations
which have been performed within the CASCADE UK project over West
Africa and finer-resolution runs carried out with the MesoNH model
over The Sahel). The formulation, or parametrization, is to be further
applied in an off-line mode to meteorological reanalyses of surface
wind speeds that feed the dust emission model. The work involves
collaborations with researchers from other laboratories, in particular
from the LISA in France and the University of Leeds in the United

The candidate will hold a PhD degrees in atmospheric physics with
experience in convective and turbulent processes. Experience with
mesoscale modelling and convective parametrizations would be greatly
appreciated as well as capability in observational data handling. Good
programming skills (FORTRAN90, Unix shell, graphic sofwares...) are
required. Fluency in English is necessary.


The centre national des recherches météorologiques - groupe d'études
de l'atmosphère météorologique (CNRM-GAME) is the research centre of
Meteo-France, the French weather service and also an unité mixte de
recherche du CNRS.The laboratory hosts approximately 275 permanent
positions (one third being research scientists), and about 60 students
and visitors. The mesoscale meteorology group leads studies on
mesoscale and microscale processes of the atmosphere and its
interfaces. Research topics are cloud physics, boundary layer,
soil-vegetation-atmosphere transfers, remote-sensing of continental
surfaces, mesoscale predictability, high-impact weather events and
climate change impacts. Research seeks to improve the representation
of the mesoscale processes within numerical weather prediction and
climate models through development and improvement of physical


Applicants will send the following to, and
[1] a curriculum vitae (including research experience, publications
and conferences, computing skills and different language practice…)
[2] a brief statement of research interests
[3] names and contact details (email + telephone number) of three referees
