The wave group has recently published work in the Computers and Fluids journal. The work focuses on the performance analysis of the internally developed tsunami code: Volna-OP2. Volna-OP2 is a robust and efficient code capable of simulating the complete life cycle of a tsunami whilst harnessing the latest High Performance Computing architectures.

An in-depth error analysis of the numerical scheme implemented in the code is given, with a novel decomposition of the numerical errors into the dispersion and dissipation components explored. Most tsunami codes exhibit amplitude smearing and/or phase lagging/leading, so the error decomposition shown here is a new approach and novel tool for explaining these occurrences. 

To date, Volna-OP2 has been widely used by the tsunami modelling community. In particular its

The UCD Wave Group performs a lot of numerical simulations of nonlinear water waves. The UCD Wave Group was successful with its PRACE DECI 16 application. The UCD Wave Group has been given 3M core-hours. They will benefit both the HIGHWAVE and the RESOURCECODE projects.

A new series of weekly webinars on Mathematics of Planet Earth will start on Friday 8th May at 15.30 CEST (14.30 BST).

These webinars are designed to give the opportunity to early career researchers, PhD students and Post-Docs, working on topics related to Mathematics of Planet Earth, to share their work with researchers at all levels in the field.

The following topics will be covered:

1. PDEs and SPDEs in fluid-dynamics;
2. Numerical models for fluid-dynamics;
3. Dynamical systems: critical transitions and linear response in the Earth system;
4. Data analysis methods for climate records.

The deadline to register as a speaker or attendee is May 7th (at midnight CEST).

If you would like to participate as an attendee or a speaker please visit https://sites.google.com/view/mpe2020-webinars/home for more details.

My first task as the newly elected Vice President of the SIAM-IMA Dublin area student chapter was to produce a short video detailing my research. My research focuses on the development of operational tools for tsunami warning centres. As this video was aimed at introducing my research to a wide audience, it simply provides a brief introduction. So if you would like to learn more about the fascinating dynamics of tsunamis and how warning centres try to mitigate their damages, please check out the quick 4 min video here: https://www.youtube.com/watch?v=BMWprUeGPa0

Making this short video doubled as great practice for the Flash Talk series run by UCD's Earth Institute. This series was organised to mark the 50th anniversary of Earth Day.

“F.O.D.—a First. Only. Different. We are a very select club, but there are more of us out there than you’d think. We know one another on sight. We all have that same weary look in our eyes. The one that wishes people would stop thinking it remarkable that we can be great at what we do while black, while Asian, while a woman, while Latino, while gay, while a paraplegic, while deaf. But when you are an F.O.D., you are saddled with that burden of extra responsibility—whether you want it or not.” [1, Chapter 8]

The International Day of Women and Girls in Science took place on February 11^th, 2020. Its aim is to raise awareness
