Using ECMWF's Forecasts (UEF2022)

Météo-France is facing a decreasing man-power dedicated to weather forecasting whereas in the meantime more and more weather data become available to the forecasters. Therefore, in the last couple of years, several products and technologies have been developed to quickly visualize those data. One of those technologies is a automated surveillance system that warns forecasters of a possible...

Effective visualisations can take a lot of time and experimentation to get right. Having an interactive environment in which to try out different aspects such as colour schemes can drastically reduce the time required. An interactive environment is also a great way to dynamically explore data, look for features and compare different datasets. On top of this, it can be essential to pre-process...

Advances in numerical weather prediction regularly produce more skilful and far-ranging predictions of the atmospheric state – but at the cost of increased complexity. As resolution becomes finer and ensemble sizes grow, it becomes ever-more difficult to track why a forecast system predicts a certain outcome: despite their basis in theory, our NWP systems often end up being treated simply as...

Floods cause between thousands and tens of thousands fatalities, affect hundreds of millions of people, and cost tens of billions of dollars every year. Google’s Flood Forecasting Initiative aims to provide actionable flood warnings to local agencies, NGOs, and the public, especially in those regions where little to no other warning systems are available. Starting 4 years ago with a small...
