ECMWF is searching for a highly motivated Scientist (A2) to conduct scientific research on evaluating (1) the representation of ocean and sea ice model uncertainty and mesoscale features in ECMWF coupled predictions and (2) understanding their local and remote impacts on weather and climate variability.
You will perform numerical experimentation with stochastically perturbed parameters (SPP) in the ocean and sea ice model, to assess potential improvements to the ECMWF climate predictions in affordable eddy-permitting configurations. This will involve (1) diagnostic work on ensemble reliability, climate mean and trend and (2) evaluation of air-sea-ice interactions at the ocean mesoscale and impacts on the large-scale atmosphere circulation. The impact of stochastic parameterisations on air-sea-ice interactions and the associated atmospheric response, will be evaluated and compared with results from benchmark eddy-rich ocean-atmosphere simulations (including IFS-FESOM and IFS-NEMO) and idealised IFS sensitivity experiments .The research and development will take place in close collaboration with colleagues in the Earth System Predictability Section and with external partners in the ACCIBERG and EERIE projects.
Your responsibilities:
- Develop and apply diagnostics to understand the atmospheric response to air-sea-ice interactions in (1) eddy-permitting configurations with and without ocean/ice SPP, (2) benchmark eddy-rich simulations, and (3) idealised IFS sensitivity experiments
- Perform numerical experimentation to study the potential benefits of implementing stochastic physics in the ocean and sea ice on ECMWF's subseasonal-to-seasonal forecasts
- Contribute to timely delivery and high quality of relevant ACCIBERG and EERIE results, as well as their contribution to ECMWF’s goals
- Communicate and document scientific results and software developments in technical reports, journal publications, conferences and meetings as appropriate
