Keynote Speaker

Richard Lawrence

IT-Fellow - Supercomputing, Met Office

Modelling clouds in the cloud

Abstract: The Met Office has signed a multimillion-pound agreement with Microsoft to provide a world-leading supercomputing capability that will take weather and climate forecasting to the next level.

In his talk, Richard will explain how the government was convinced to invest a significant amount of money in a world changing IT upgrade.

  • Understand the workings of the Met Office and how it makes use of Supercomputers
  • Learn how government spent £1bn on supercomputing
  • Gain insight into how you move 1 petabyte of data a day

Short biography: Specialising in supercomputing architecture, Richard is accountable for the technical design, implementation, and future direction of one of the world’s largest supercomputers dedicated to weather and climate research.

As the programme architect for the Met Office’s Supercomputer 2020+ programme, he led the work on the Data Centre, Connectivity and Scientific Compute Environment packages and oversaw the requirement capture and design of the Active Data Archive expected to handle 1PB of data a day with a capacity of ~4 Exabytes.

Richard holds a MEng in Software Engineering at Aberystwyth University and is a Chartered Engineer and Chartered IT Professional.

Future development of the Azure HPC platform, applications and intelligent services

Abstract: Researchers and scientists can now, more than ever, more accurately simulate, predict and analyse a broad range of topics – from extreme weather events to population health.

Some of these discoveries can help inform government policy and support strategies that help mitigate and address potentially severe impacts on our planet and its inhabitants.

Microsoft Azure provides a differentiated cloud-HPC platform with a wealth of applications, intelligent services, focused collaborations and technical support to help address some of these big challenges: but what does the future look like? What are the opportunities – and the challenges?

Surface-to-space atmospheric waves from Hunga Tonga-Hunga Ha’apai eruption

Abstract: The January 2022 Hunga Tonga–Hunga Haʻapai eruption was one of the most explosive volcanic events of the modern era, producing a vertical plume which peaked > 50km above the Earth. The initial explosion and subsequent plume triggered atmospheric waves which propagated around the world multiple times. A global-scale wave response of this magnitude from a single source has not previously been observed.

The Hunga Tonga eruption represents an important natural experiment in how the atmosphere responds to a sudden point-source-driven state change, which is of use for improving weather and climate models.

We used a comprehensive set of satellite and ground based observations, pre-processed for analysis using HPC, to quantify this response from surface to ionosphere. A broad spectrum of waves was triggered by the initial explosion, including Lamb waves at all heights and gravity waves in the middle atmosphere.

Gravity waves have not previously been observed propagating at this speed or over the whole Earth from a single source. Latent heat release from the plume remained the most significant individual gravity wave source worldwide for >12 hours, producing circular wavefronts visible across the Pacific basin in satellite observations. A single source dominating such a large region is also unique in the observational record.

Posters

We will post the Title and Abstract of posters here when we receive them.

Help us make this a great Research Computing Community event! We are inviting your submissions of contributed talks or posters on all aspects of HPC-enabled research.

Submissions from all supercomputing groups are highly encouraged - from PhD students through to senior researchers and research groups. The symposium is an internal University event that provides a friendly and informal setting for knowledge sharing.
