[Met-jobs] PostDoc: Gravity waves parameterization in Climate models (LMD/Paris)

Post-Doc announcement at LMD (Paris)

Postdoc at LMD/ENS (Paris): Gravity waves parameterization in Climate models.

Responsible: François Lott in collaboration with R. Plougonven, H. Hertzog and 
A. Podglagen from LMD.

A 2-year post doctoral position is opening at the “Laboratoire de Meteorologie 
Dynamique” to work on the parameterization of atmospheric gravity waves in the 
IPSL Climate model. The candidate will develop off-line versions of the 
operational subgrid scale parameterizations of gravity waves that are related 
to mountains (Lott and Miller 1997), convection (Lott and Guez 2013) and fronts 
(de la Camara and Lott 2016) and guide them with analysis field from  ECMWF.  
The candidate will then vary the parameters of the schemes to give the best fit 
against balloon observations. Then, the IPSL model will be launched over long 
periods (climate), and the impact of the updated scheme on various key climate 
modes will be tested. The candidate will then test if the changes made in the 
parameterization impact the model climate in climate change scenarios. 

Depending on the his own skill and desire, the candidate could instead  conduct 
research to improve our understanding of the mountain drag forces.  The 
contribution of the gravity waves to that force, and in the presence of 
atmospheric boundary layers and trapped lee waves will be ascertain.  We seek 
to develop parameterizations that handle orographic boundary layer drag and 
gravity wave drag on the same basis, distinguishing the two according to the 
low level flow stability.  The candidate  will develop theory and test impacts 
in the IPSL Climate  model again, may be in the ECMWF model. 

The candidate will actively interact with an international consortium (USA, UK, 
Germany, France).

Employment conditions
The position opens for two years, salaries according to the local french 
standards (around 2500E net/month but this depends on experience and includes 
social insurances). This call is opened until Feb, 20, 2021. Starting date: as 
soon as possible.

PHD in atmospheric sciences, geophysical fluid dyamics, climate dynamics or 
related fields.
Publication(s) in peer-reviewed international journals
Experience in modeling, programming, data management.

Document requested:
Applicants should send via e-mail to François Lott: (i) a statement of research 
experience, qualification and interest, (ii) a complete CV including a list of 
publications, and (iii) the name of at least two scientists who would agree to 
send a letter of recommendation.
