We are looking for a highly motivated Scientist to improve the representation of cloud and precipitation processes for global km-scale resolution simulations with ECMWF’s Integrated Forecast System (IFS), in the framework of ECMWF’s contribution to the Destination Earth (DestinE) initiative of the European Commission. This is an exciting opportunity to be part of a team pushing the bounds of global modelling as part of the efforts to operationalize and continuously evolve the global component of the DestinE Weather-induced Extremes Digital Twin (Extremes DT) and the Climate Adaptation Digital Twin (Climate DT). Clouds and precipitation are of fundamental importance for weather prediction and climate projections, and there are many challenges to improve their representation in models, including the appropriate level of complexity of microphysical processes, spatial heterogeneity, and interactions with radiation, turbulence, parametrized convection and resolved dynamics. Particularly for km-scale resolutions, deep convection becomes partially resolved and there is increasing emphasis on the formulation of the microphysics for convective storms. The successful candidate will evaluate and further develop the representation of cloud and precipitation processes in the IFS investigating the impacts of a more complex implementation (e.g. representation of graupel, ice phase, particle number concentrations) and interactions with other processes. Assessments will range from local impacts of extreme precipitation events to large-scale impacts on the global circulation for both simulations on a timescale of a few days ahead in the Extremes DT to multi-annual simulations in the Climate DT and Horizon 2020 project nextGEMS.
This position is based in the Physical Processes Team, responsible for the improved representation of atmospheric processes within the ECMWF IFS. The team is part of the Earth System Modelling Section of the Research Department at ECMWF. You will report to the Physical Processes Team Leader and will work closely with other scientists across ECMWF on the IFS and the development of the DestinE Digital Twins both at ECMWF and at partner institutions involved in the implementation of the Climate DT.
At ECMWF, you will find a passionate community, collectively aiming to build world-leading global Earth system models for numerical weather prediction and climate simulations. This effort supports ECMWF’s strategy of producing cutting‐edge science and world-leading weather predictions and monitoring of the Earth system. This contract is funded by Destination Earth and the H2020 project nextGEMS.
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 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.
ECMWF has 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 one of the three entities entrusted to implement the Destination Earth (DestinE) initiative of the European Commission, alongside ESA and EUMETSAT as partners. DestinE aims to deploy several highly accurate thematic digital replicas of the Earth, called Digital Twins. The Digital Twins will help monitor and predict environmental change and human impact, in order to develop and test scenarios that would support sustainable development and corresponding European policies for the Green Deal. ECMWF is responsible for the delivery of these digital twins and of the Digital Twin engine, the software infrastructure needed to power them of some of Europe’s largest supercomputers, those of the European HPC Joint Undertaking (EuroHPC).
The second phase of DestinE covers the period June 2024 – May 2026, and future phases are foreseen (subject to funding). Phase 2 will focus on early operations with consolidation, maintenance, and continuous evolution of the DestinE system components developed in the first phase.
