Esperanza Cuartero and Julia Wagemann take us through this year’s projects.
Progress in sub-seasonal forecasting of weather extremes04 October 2022As their work under the EU-funded CAFE project draws to a close, ECMWF scientists Emmanuel Rouges and Nikolaos Mastrantonas highlight the progress they’ve achieved in forecasting extreme conditions over Europe at the challenging sub-seasonal timescale.
Predicting the impact of new satellites on ECMWF’s forecasts16 June 2022ECMWF’s Ensemble of Data Assimilations is providing a novel and efficient way to assess the impact of new satellite observations and to help inform the development of the Global Observing System. Sean Healy and Katrin Lonitz discuss some of the latest work.
Radio Frequency Interference: an NWP perspective on the RFI 2022 workshop14 March 2022Radio frequency interference poses serious risks to numerical weather prediction and other fields. Stephen English takes us through the key issues discussed at the RFI 2022 workshop on monitoring, mitigation, and management.
ECMWF – a stimulating and diverse working environment08 March 2022On International Women’s Day, ECMWF’s Director-General Florence Rabier discusses working in the diverse environment of ECMWF, in a field that has fascinated her since childhood.
Secondment at ECMWF on the Maestro project31 January 2022Over his nine-month secondment at ECMWF, Miloš Lompar from the Serbian Met Service worked with Domokos Sármány and others in Production Services as part of the Maestro project looking at novel technologies for data input/output – currently one of the major bottlenecks in ECMWF’s Integrated Forecasting System.
Machine learning to emulate components of ECMWF’s Integrated Forecasting System13 December 2021Matthew Chantry and Peter Dueben look at the expanding range of projects exploring the use of machine learning within the Centre’s forecasting system.
ECMWF Summer of Weather Code 202101 November 2021Julia Wagemann and Esperanza Cuartero discuss the cutting-edge innovations and high-quality open-source developments from this year’s Summer of Weather Code.
Advancing high-performance data management in the EuroHPC ACROSS project13 October 2021Following the opening of ECMWF's data centre in Bologna and offices in Bonn, Emanuele Danovaro highlights the opportunities this brings for collaboration in the EuroHPC ACROSS project.
CALIPSO: 15 years of cloud and aerosol lidar data from space28 June 2021For the last 15 years, the CALIPSO satellite has been providing a unique, three-dimensional view of clouds and aerosols. Our scientists look back at its contribution to weather forecasting and atmospheric monitoring.
Better glimpses of the future with global storm-resolving simulations02 June 2021Irina Sandu and Bjorn Stevens present a European effort to build the next generation of Earth system models in the H2020 project NextGEMS.
Assimilating soil moisture scatterometer data using neural networks26 April 2021Patricia De Rosnay and colleagues discuss a recent study which uses neural network techniques to derive soil moisture from satellite observations. Neural networks are shown to outperform operational methods in some regions.
Large-scale machine learning applications for weather and climate12 April 2021The machine learning for scalable meteorology and climate (MAELSTROM) project began in April 2021. Peter Dueben, project coordinator, talks about its aims and the importance of co-design projects for concerted developments of applications, software, and hardware design.
The importance of additional surface-based observations in data-sparse regions22 March 2021Data from surface-based observations are vital for skilful forecasts, but significant areas of the globe remain comparatively poorly observed. Bruce Ingleby looks at the role that surface-based observations play and the impact of gaps in coverage.
Extreme precipitation and large-scale flow patterns in the Mediterranean01 March 2021Following a recent publication, Nikolaos Mastrantonas discusses the spatio-temporal characteristics of extreme precipitation events across the Mediterranean and their connection to large-scale atmospheric flow patterns.
New insights into polar observing systems using numerical models08 January 2021Irina Sandu and François Massonnet (Université Catholique de Louvain) discuss polar observations, their impact on forecasting, and how the development of observing systems goes hand in hand with the development of numerical prediction systems.
2020 – a crazy year (for satellite navigation data and NWP)!18 December 2020Sean Healy has had a crazy year – and for a change we are not talking about COVID. Despite the restrictions of working from home, Sean and colleagues at the Centre have achieved remarkable progress in the use of data from global satellite navigation systems to improve our forecasts.
