Domaine scientifique : Gravity wave parameterization in Climate models: development and calibration of source related parameterizations.
Description du poste :

A 2-year post doctoral position is opening at the “Laboratoire de Météorologie Dynamique” to work on the parameterization of subgrid scale 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).

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

Compétences requises :
Rémunération : The position opens for two years, salaries according to the local french standards (around 2500E net/month but this depends on experience) it will stay opened until completed.
