[Met-jobs] Post-doctoral Position at CNRM (France)

Applications are invited for a post-doctoral position at the CNRM
addressing tropical Atlantic atmospheric biases in the CNRM climate
model. The deadline for application is 15 May 2016.

Context:

The « Centre National des Recherches Météorologiques » (CNRM) is the
research center of Meteo- France, the French weather service. To carry
out its missions, CNRM hosts approximately 275 permanent positions (one
third being research scientists), and about 60 students and visitors,
working in specialised divisions. The climate group, GMGEC, is one of
these divisions. Its main specific research activities concern the
development of climate models, the studies of climate variability and
change at global and regional scales, of long-range forecasting, of
atmospheric chemistry and of ocean-air interactions. Besides, the CNRM
climate group has recently developed a new version of its global coupled
climate model including a deeply revised set of atmospheric
parameterisations. This new model will be used for the CMIP6 exercise.
The Tropical Atlantic is a region of key uncertainty in earth-climate
system: state-of-the-art climate models exhibit large systematic error
and climate change projections are highly uncertain over this region as
well as for the West African monsoon. Any improvement of the models over
the tropical Atlantic could increase our confidence on African monsoon
projections, which could have strong implications over this highly
populated region. Only few models have significantly improved in this
region from CMIP3 to CMIP5. The EU project PREFACE
(<http://preface.b.uib.no/>) aims at reducing these systematic errors to
reduce the uncertainty of seasonal hindcasts and climate projections.

Job Description:

The successful applicant will first document the behaviour of the new
CNRM climate model (CNRM- CM6) over the tropical Atlantic region. Then
he/she will identify leading-order mechanisms responsible for the
development of systematic coupled model biases. To achieve this, he/she
will focus on the analysis of the systematic drift in existing
integrations using full-field initialisation from observations (Toniazzo
and Woolnough, 2013), using high-frequency diagnostic output in both
oceanic and atmospheric components. Sensitivity experiments will then be
conducted with the CNRM-CM model in hindcast mode to isolate relevant
processes and model weaknesses (clouds convection and large scale dynamics).

The work will be carried out at CNRM (Toulouse, France) but with strong
interactions with Cerfacs (Toulouse) also involved in the PREFACE
project and using CNRM-CM. The applicant will benefit from the
collaborative framework of the PREFACE project.

Applications:

The candidate should have a PhD with experience / knowledge in climate
modelling, atmospheric physics modelling and ocean-atmosphere
interactions. The candidate should be autonomous and able to work with
computing tools such as FORTRAN and/or python, and with complex model
codes in UNIX environment. He should also have good communication
skills. Fluency in English is necessary. Net salary of the successful
applicant will range from 2500 to 3000€/month, depending on experience.
The selected candidate will be offered a contract for 14 months.
Applications should include a CV and a cover letter, and if possible the
names of two reference persons. They should be sent to Aurore Voldoire
(<aurore.voldoire@meteo.fr>) and Romain Roehrig
(<romain.roehrig@meteo.fr>). The position will start as soon as possible
and possibly no later than September 2016. Applications should be sent
by 15 May 2016.
