Up to £1.2 billion investment has been confirmed for a state-of-the-art supercomputer to improve severe weather and climate forecasting,

Data from the supercomputer will be used to inform Government policy as part of leading the global fight against climate change and meeting net zero emission targets.

Predicting severe weather and the impacts of climate change will be faster and more accurate than ever before, thanks to confirmation of up to £1.2 billion government funding to develop a state-of-the-art supercomputer, Business and Energy Secretary and COP26 President Alok Sharma announced today (17 February 2020).

Data from this new supercomputer – expected to be the world’s most advanced dedicated to weather and climate – will be used to help more accurately predict storms, select the most suitable locations for flood defences and predict changes to the global climate.

The new supercomputer, to be managed by the Met Office, will also be used to help ensure communities can be better prepared for weather disruption, including through:

  • More sophisticated rainfall predictions, helping the Environment Agency rapidly deploy mobile flood defences
  • Better forecasting at airports so they can plan for potential disruption; and
  • More detailed information for the energy sector to help them mitigate against potential energy blackouts and surges

With the Government announcing its Year of Climate Action, the news further demonstrates the UK is leading by example ahead of hosting UN climate conference COP26, where the world will meet to agree more ambitious action.

Business and Energy Secretary and COP26 President Alok Sharma said:

“Over the last 30 years, new technologies have meant more accurate weather forecasting, with storms being predicted up to five days in advance.

“Come rain or shine, our significant investment for a new supercomputer will further speed up weather predictions, helping people be more prepared for weather disruption from planning travel journeys to deploying flood defences.”

The new supercomputer will also strengthen the UK’s supercomputing and data technology capabilities, driving forward innovation and growing world-class skills across supercomputing, data science, machine learning and artificial intelligence. 

Professor Penny Endersby, Met Office Chief Executive said:

“This investment will ultimately provide earlier more accurate warning of severe weather, the information needed to build a more resilient world in a changing climate and help support the transition to a low carbon economy across the UK.

“It will help the UK to continue to lead the field in weather and climate science and services, working collaboratively to ensure that the benefits of our work help government, the public and industry make better decisions to stay safe and thrive. 

“We welcome this planned investment from UK Government.”

Chair of the Science Review Group Professor Ted Shepherd said:

“The agreement to upgrade the Met Office high performance computer is welcome news. The improved processing power will deliver a step-change in weather forecasting and climate modelling capability for the UK, such as the further development of the Earth Systems Model, which involves collaboration with the many UKRI-NERC funded research centres.

“Improved daily to seasonal forecasts and longer-term climate projections will equip society with a greater ability to proactively protect itself against the adverse impacts of climate change.”

The Met Office is at the forefront of supercomputing, using its current technology to drive advances in environmental forecasting.

As a result, detailed weather predictions for the UK now take place every hour instead of every three hours, providing crucial and timely updates when extreme weather is approaching.

The benefit of this has been felt recently: major storms Ciara and Dennis, and the ‘Beast from the East’ in 2018, were forecast five days in advance, enabling local councils and emergency services to prepare and instigate resilience plans.  Similarly, the Environment Agency has used the Met Office’s latest UK climate projections to set out potential future flooding scenarios and how funding can be best allocated.

UK supercomputer investment and breakthroughs

Today, the Government also announced £30 million investment for advanced supercomputing services, providing researchers with access to the latest technology and expert software engineers.  It will also help them speed up scientific breakthroughs like developing ‘food fingerprinting’ to detect chemical contaminants in food and improving drug design.

The funding will support seven High Performance Computing (HPC) services run by universities from across the UK, including Queen’s University Belfast, the University of Edinburgh, and Durham University. The services will provide researchers with invaluable access to powerful systems to support ground-breaking work in areas from Artificial Intelligence, energy storage and supply, and therapeutic drug design, as well as boosting the skills of UK scientists.

The Government investment will replace Met Office supercomputing capabilities over a 10-year period from 2022 to 2032. The current Met Office Cray supercomputers reach their end of life in late 2022. The first phase of the new supercomputer will increase the Met Office computing capacity by 6-fold alone. The Met Office will look to deliver at least a further three times increase in supercomputing capacity for years 6-10.

Up to £1.2bn refers to the total expected investment from Government. The expected contractual value for the supercomputing capability is £854m. Other costs include investment in the Observations network, exploiting the capabilities of the supercomputer and the programme office costs.

2020 marks the 30th Anniversary of the establishment of the Met Office Hadley Centre for Climate Science, working at the forefront of climate science and pioneering research.

High Performance Computing case studies

GW4 Tier-2 HPC Centre for Advanced Architectures (Isambard 2)

Led by: The GW4 Alliance of the Universities of Bath, Bristol, Cardiff and Exeter, and hosted by the Met Office

EPSRC support: £4.1 million

The Isambard 2 service will use the very latest technology from the UK-based Arm Holdings to provide scientists with a world-class High Performance Computing service. The same technology is expected to be used in some of the first supercomputers capable of a billion billion calculations per second, called Exascale supercomputers. This technological step change will require scientists to adapt their codes in order to run as quickly and efficiently as possible and thus accelerate scientific discovery. Isambard 2 will succeed the current Isambard system and will help enable British researchers to prepare their codes for the widespread use of Exascale systems.

Isambard has already been used to investigate potential drugs to treat osteoporosis and simulate Parkinson's disease at the molecular level. Isambard 2 will enable researchers to expand this further with the potential for scientific breakthroughs.

The AI techniques developed using the service will have impact in a range of sectors including financial services, manufacturing, energy and healthcare. The Molecular Dynamics research conducted on JADE 2 will advance understanding of the structure and function of large biological molecules, many of which are targets for therapeutic agents for a large variety of health conditions. The service will provide a valuable computing resource to the new UKRI Artificial Intelligence Centres for Doctoral training, and thus provide a critical computational capacity needed to develop the next generation of experts in AI.

Cirrus Phase II: Preparing for Heterogeneity at Exascale

Led by: The Edinburgh Parallel Computing Centre at the University of Edinburgh

EPSRC support: £3.5 million

Cirrus Phase II will expand the capabilities of the Cirrus service by adding specialized GPUs to the current system. GPUs are commonly used as graphics/video cards in mobile phones, personal computers and games consoles. However, specialized GPUs can be also be used in supercomputers as accelerators enabling them to run numerical calculations more quickly. The technology used in Cirrus is expected to be used in some of the first Exascale supercomputers and will allow scientists to test and adapt their code for modelling and simulation to be ready to advance discovery and innovation as soon as Exascale systems become available. It will help to ensure the UK has a supply of individuals trained with these specialised skills and could lead to far more rapid and detailed discoveries in new areas and the projects Cirrus has already supported, such as modelling protein shape for better drug design and simulating tidal flows to optimise turbine installations and their effects on sea beds. The new GPUs will also provide a high-performance platform for AI training and research, a critical and rapidly growing area.

Northern Intensive Computing Environment (NICE)

Led by: Durham University as part of the N8 Research Partnership (Durham and Newcastle Universities, Universities of Lancaster, Leeds, Liverpool, Manchester, Sheffield and York)

EPSRC support: £3.1 million

The new NICE service will use the same technology as that used in the current leading supercomputers in the world, extending the capability of accelerated computing. The technology has been chosen with the aim of combining experimental, modelling and machine learning approaches, bringing these communities together to address new challenges.

This will mean that machine learning can be used alongside modelling and simulation to better understand the vast data sets now being generated by experimentalists through, for example, national facilities such as Diamond and the Henry Royce Institute and international facilities such as the European Synchrotron Radiation Facility. This approach will enable scientists to, for example, advance the imaging techniques necessary to produce the next generation of X-ray instruments and develop future students working with deep learning techniques at the interface of algorithms and High Performance Computing.
