  • 1.2 billion investment confirmed for state-of-the-art supercomputer to improve severe weather and climate forecasting
  • the latest supercomputing technology will unleash the full potential of weather and climate data for the UK
  • 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 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 worlds 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 UKs 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 Offices latest UK climate projections set out potential future flooding scenarios and how funding can be best allocated.

UK supercomputer 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 Queens 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.

UK Government Minister for Scotland Douglas Ross said:

The UK Government 30 million investment in Edinburghs supercomputers helps keep our capital at the forefront of cutting edge technology.

The University of Edinburgh facility will benefit scientists from across the UK as they are given the opportunity to use this new technology. This additional funding builds on the work of the Edinburgh and South East Scotland City Region Deal which is creating world-leading hubs for AI research.

The UK Government is committed to combatting the impact of climate change on top of creating thousands of high-earning jobs and ensuring businesses and public services in the UK are the first to benefit from the latest innovations.

Notes to editors

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.

1.2 billion refers to the total expected investment from Government. The expected contractual value for the supercomputing capability is 854 million. 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.

Met Office Supercomputer Case studies

Case study 1: The Met Office supported the response to the Toddbrook Reservoir incident and the protection of residents of Whaley Bridge. It worked directly with the emergency services and organisations involved in the emergency response advising on short-term and long-term weather forecast conditions. This was critical as further rainfall would impact the water level in the Dams reservoir.

Case study 2: In a global first, the government brought together the Met Office, the University of West Virginia, the University of Maryland and NASA to help save lives by accurately predicting cholera hotspots. The Met Office provided guidance on forecasted rainfall in the country for 14 days in advance, to help UNICEF and Oxfam target their on the ground efforts to prevent large outbreaks of cholera.

Case study 3: Africa is one of the worlds most vulnerable regions to climate change with millions of people relying on rainfall for agriculture. As part of the UK aid funded IMPALA programme, the Met Office led the development of the first pan-African convection-permitting model CP4-Africa. This ground-breaking research developed high-resolution climate projections that provided a glimpse into future weather and climate extremes across Africa, which were more severe than previously thought. The information will help decision-makers reduce climate-related risks.

Case Study 4: UK Climate Projections (UKCP) provides the most detailed picture yet of future climate in the UK. As part of this, UKCP Local (2.2km) provides the most realistic set of projections of future climate extremes like soaring temperatures during the summer and hourly summer rainfall for local areas in the coming decades. This enhanced detail could help inform future risk assessments and local decision-making on the future of climate change. The UKCP toolkit will be used to inform the next Climate Change Risk Assessment, due in 2022, and is being widely used by local authorities, industry and academia to help inform plans to manage future climate risks and enhance resilience.
