Topic: High-performance numerical weather prediction at ECMWF

The skill of ECMWF’s weather forecasts has improved continuously for over three decades, with each decade of research and development delivering another day in lead time. Nowadays, for example, we are able to accurately predict the tracks of tropical cyclones even more than a week before they make landfall. This achievement is thanks to a multitude of technologies allowing us to observe, describe, and compute the weather with greater and greater detail and physical fidelity. An important factor underpinning this development has been a steady increase in compute power which has enabled an increase in model resolution, from 125 km in the 1980s to 9 km today, with a prospect for 5-km resolution forecasts in the next few years. However, running such high-resolution forecasts efficiently will require careful exploitation of the next generation of supercomputers, which will be even more massively parallel and heterogeneous. This talk will be about ECMWF’s efforts in computational science to enable weather forecasts at a resolution of up to 1 km to run efficiently on these supercomputers. I will summarise our research carried out on a number of Top 10 supercomputers, much of it supporting the goals of the European Union’s new Destination Earth initiative. I will also touch on ECMWF’s activities in machine learning and data assimilation.

Date: 9th Nov 2022, Wednesday (11:00am – 12:00pm)
Presenter: Ryan Kang (CCRS)
Topic: The ‘Walstad’ method on creating an optimal multi-system seasonal super-ensemble for Southeast Asia

The Walstad Method is a natural method for making your own balanced aquarium (or ecosystem) that can be almost completely self-sufficient without a filter or regular water changes. In this seminar, I will apply these Walstad’s concepts to create an optimal multi-system seasonal super-ensemble for Southeast Asia. Also, a confluence of three ‘game-changer’ events (operationalisation of C3S Data Store in 2008, availability of key updates in the python packages Xskillscore and Xclim in 2020/21 and SSP team’s ideas in 2022) needed for a proper execution of this ‘optimal combination’ methodology will be briefly introduced.


About the CCRS seminar series

CCRS hosts a regular seminar series to share scientific progress in areas of relevance to CCRS and MSS activities, amongst our staff as well as with our collaborators.

These seminars serve also to connect the wider research communities interested in these topics. As such, we actively encourage and promote participation in the seminar series from the local and international researchers/practitioners in the field of earth sciences. You can find out more about the topics that were covered and the seminar speakers from the list of the past talks below.

If you wish to be kept updated on upcoming seminars or to present your research in the CCRS seminar series, or just to find out more about our seminar series, please contact us at for more details.
