The 2022 edition is devoted to couplings at the ocean-atmosphere interface and to the challenges of adapting to new computing architectures.
IYA 2022 will be held from 7 to 10 June 2022 at the Météo-France International Conference Centre in Toulouse.
Two themes are proposed:
- Couplings at the ocean-atmosphere interface (from 7 p.m. to 9 p.m.);
- the challenges of adapting to new computing architectures (from 9 p.m. to 10 p.m.).
The first theme, couplings at the ocean-atmosphere interface, focuses on the study of physical processes involving interactions between the atmosphere and different states of the ocean surface, the coastline on a global scale and the climate. IYA 2022 aims to take stock of current knowledge by establishing how modelling tools and observation can be used to characterise ocean-atmosphere interactions, and to understand how exchanges between the atmosphere, the surface and deep ocean, waves, river inputs and sea ice affect atmospheric evolution on different scales and the properties of the sea surface, such as its roughness or colour, its level, and its emissions of heat, freshwater, momentum or greenhouse gases.
Presentations on the following subjects will be particularly welcome: observations at the marine surface, measurements and representations of atmospheric and oceanic boundary layers, turbulent surface flows and parameterisation, ocean/wave/atmosphere data assimilation, marine forecasting, dynamics of the coastal environment including tides and coastal deformations (uncovered banks, coastal flooding, foreshore), intense events including tropical cyclones, coupling in the polar regions and sea ice, interactions between coupled and cloud processes, marine chemistry and aerosols.
In addition, presentations on new developments are encouraged, including for example the description of new coupling strategies using innovative numerical methods, the use of nested modelling or variable refined horizontal grids.
The second theme, the challenges of adapting to new computing architectures, focuses on the challenges of adapting to new computing architectures. Presentations on the following topics are welcome:
- new computing and memory technologies ;
- examples of adapting modelling or data assimilation code, in particular to processors equipped with accelerators ;
- design, use and long-term development of "domain-specific languages" (DSLs), and positioning in relation to more traditional compilers and libraries of scientific functions;
- approximation of algorithms using deep learning methods, and positioning in intensive scientific computing;
- the implications of these changes on the balance of functions between research into geophysical or environmental issues, research into computational engineering and their impact on the organisation of teams, laboratories and projects.
During the workshops, the André Prud'homme 2022 Prize will be officially awarded by Météo et Climat to Alex Ayet for his thesis, defended on 9 September 2020 at the Université de Bretagne Occidentale and entitled "Flux de quantité de mouvement à l'interface air-mer : approche théorique du couplage entre turbulence et vagues de vent".
Authors will have the opportunity to present their work - preferably in French - in the form of a 15 or 20 minute talk during themed plenary sessions or in the form of posters during a poster session.
Short abstracts must be submitted by 3 April 2022 (registration/abstracts tab).
At the end of the workshops, the written papers (abstracts, presentations and posters) will be published on this website, unless otherwise stated by the authors.
All participants must register for the workshops before 20 May 2022.
Access to the Météopole site is regulated for external participants.
