Infrasounds and Gravity waves
A 1-yr Post-Doctoral position is opened in Paris to work on the interaction between gravity waves and infrasounds. The main objective is to analyse whether infrasounds data, as those collected by the IMS (International Monitoring System) network, can be used to infer the atmospheric states through which the infrasounds have propagated. To produce realistic atmospheric states, meteorological analysis products will be used in combination with stochastic gravity waves prediction models, similar to those that are used in the Atmospheric General Circulation Models (AGCMs) to parameterize gravity waves. The primary research focus will be on how tuning the parameterization schemes from recorded infrasound signals. This fellowship may be extended for a second year, providing either that the candidate (i) aims at studying infrasound propagation through mountain gravity wave fields predicted by high resolution atmospheric models, or (ii) analysing the impact of newly tuned gravity waves parameterization schemes on the stratospheric climate by using the LMDz AGCM. These two objectives fall under the framework of the ARISE2 European project (http://arise-project.eu/).
We seek a highly
motivated individual with a Ph.D in a discipline related to
geosciences and/or statistics. Publication in a high quality
is required. Interested applicants should submit a cover letter,
to F. Lott and C. Millet.
Starting time: January
2016, possibilities of a 2d year prolongation
