UK Meteorological Office and Microsoft are to build a weather forecasting supercomputer in the United Kingdom. The Government of the United Kingdom is to invest 1.2 billion Pound Sterling in the project.


  • It is expected to be one of the top 25 supercomputers in the world.
  • It will help in better understanding of weather Climate Change.
  • The supercomputer will provide the following:
    • Provide detailed weather models
    • Help to improve localised forecasts
    • Run more potential weather scenarios
    • Help predict severe weather
  • It is to run completely on renewable energy. This will help to save 7,415 tonnes of Carbon Dioxide (CO2) in one year. Supercomputers release huge amounts of heat and thus a strong cooling system is required for their operation. Thus, energy required to maintain supercomputers is high.
  • It will have more than 1.5 million processor cores
  • The supercomputer will be able to do 60 quadrillion calculations per second, which is 60,000,000,000,000,000.

Benefits of Supercomputer

  • The Supercomputer will be used to create detailed city scale simulations to provide localised climate reports.
  • Supercomputer will help the aviation industry with an accurate forecast of temperature and wind information. This in turn will help to improve the fuel efficiency.
  • It will help United Kingdom to achieve its net Zero target by 2050.

About Supercomputers

  • Since the 2017 the top 500 supercomputers of the world are running on Linux-based Operating System (LBOS).
  • The performance of supercomputers is now measured in Floating Point operations per second called FLOPS. Earlier they were measured in Million Instructions per Second.
  • Lenovo became the largest provider of Top 500 supercomputers. It has provided 117 units of the top 500 supercomputers in the world.
