Scientist – Ocean and Sea Ice Variability and Predictability

Your role 

We are 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.

About the Earth System Predictability Section

The Earth System Predictability Section is part of ECMWF’s Research Department. The Section explores relevant directions to improve the skill of the ECMWF forecasting systems. This involves both exploring the predictability horizon of the earth system, as well as identifying those elements limiting the actual forecast skill. The aim is to guide future development of the ECMWF Seamless Earth-System forecasting system.

Within the Earth System Predictability Section, the extended-range Prediction Team is responsible for the design of the ECMWF extended-range prediction system, which currently covers forecasts up to 46 days ahead. The team conducts predictability research to inform on the representation of sources of sub-seasonal predictability, as well as identifying critical elements to translate predictability into prediction skill.

About ECMWF

The European Centre for Medium-Range Weather Forecasts (ECMWF) is a world-leader in weather and environmental forecasting. As an international organisation we serve our members and the wider community with global weather predictions and data that is critical for understanding and solving the climate crisis. We function as a 24/7 research and operational centre with a focus on medium and long-range predictions, holding one of the largest meteorological data archives in the world. The success of our activities builds on the talent of our scientists and experts, strong partnerships with 35 Member and Co-operating States and the international community, some of the most powerful supercomputers in the world, and the use of innovative technologies and machine learning across our operations. 

ECMWF has also developed a strong partnership with the European Union and has been entrusted with the implementation and operation of the Destination Earth Initiative and the Climate Change and Atmosphere Monitoring Services of the Copernicus Programme. Other areas of work include High Performance Computing and the development of digital tools that enable ECMWF to extend provision of data and products covering weather, climate, air quality, fire and flood prediction and monitoring. 

ECMWF is a multi-site organisation, with a main office in Reading, UK, a data centre/supercomputer in Bologna, Italy, and a large presence in Bonn, Germany. We appreciate the need for flexibility in the way our staff work and staff have the option to mix office work and teleworking up to 10 days/month.
