A Postdoctoral fellowship is available at IPSL/LOCEAN laboratory to work within the H2020 EUCP European project.
This fellowship aims at improving the robustness of the evaluation of decadal predictions predictive skill. Decadal prediction represents a recent challenge in the climate community, especially with the development of climate services. It consists in using observations to constrain the initial conditions of the climate projections, in order to initialise the phase from the natural modes of climate variability and thereby provide a forecast at the decadal timescale. Within the ongoing 6th climate models intercomparison project, tenths of modelling groups are developing such prediction systems. Yet, estimating the skill that arises from this system is not straightforward. It indeed depends on several steps: debiasing, detrending, use of a multi-model etc. Here, a specific issue will be tested: the mean state debiasing. For this, we will use a statistical procedure initially developed for centennial simulations. This procedure has been proved to efficiently improve the capacity of climate simulations to be used for local impact studies. Here, we propose to use test the impact of this procedure for decadal prediction simulations.
This study will be performed within the EUCP project, which aims at developing an innovative European regional ensemble climate prediction system. In this framework, a large effort is put into evaluating and improving the decadal climate predictions in order to support practical and strategic climate adaptation and mitigation decision tasking. Results from the work proposed here may thus be directly used and promoted by impact studies carried within the project.
We expect a PhD in oceanography, meteorology, environmental sciences or similar research experience.
The postdoctoral fellowship will be located at IPSL/LOCEAN laboratory located in the heart of Paris, with close collaboration with the EPOC laboratory. The IPSL-EPOC decadal prediction team is composed of four permanent researchers. Four other postdoctoral fellows are also part the team at the same time as the present proposal, one involved in the same EU-H2020 project (EUCP). This will ensure stimulating interactions within and outside the research group. The IPSL-EPOC decadal prediction team also benefits from the enthusiastic scientific environment both in Paris and Bordeaux, notably both the NEMO and the IPSL coupled model developing teams, both of which will be key within the fellowship.
The postdoctoral fellowship will be primarily supervised by Didier Swingedouw and Juliette Mignot, with strong involvement of Eric Guilyardi and Guillaume Gastineau as well as the statistical development team of IPSL.
