OBJECTIVES OF THE WORKSHOP

 

The overall objective is to review the scientific and technical progresses achieved with the DRAKKAR hierarchy of model configurations based on the NEMO platform, identify strengths and weaknesses of these models, and discuss key model improvements and new developments that are needed for the future. The workshop is open to contributed talks from participants, but high priority is given to discussions.

Speakers are encouraged to present their most recent results or ongoing research. Candid presentations of "things that do not work" in the numerical simulations are welcomed, because they foster interesting discussions and contribute to the progress of the modelling community.

 

CONTRIBUTIONS

 

1 - Abstract submission (opens 15 November 2019, closes 20 December 2019).

Send your abstract to bernard.barnier@cnrs.fr and copy to anne.marie.treguier@ifremer.fr

Please indicate your preference for oral or poster presentation.

 

2 - Content of Presentations.

The talks at the Drakkar workshop are not meant to be of the same type as EGU or AGU. For this reason, we recommend that your contributions emphasise the scientific content of your studies as well as model development issues, with the aim to contribute to the open discussions on improving the quality of ocean models and global ocean model configurations.

 

A poster session will be organized on Tuesday, February 4th. Note that posters will be exposed during the whole duration of the workshop (Monday to Wednesday), giving additional time for discussion during breaks.

 

When presenting the results of their research, speakers are invited to consider how their results contribute to the main foci of this year workshop. The foci, which will drive the organization of the workshop agenda, are given below.

 

Foci of the 2020 Workshop

1 ) Ocean variability and processes in high resolution models

This session will present results from simulations resolving the mesoscale or submesoscale (global, basin-scale or using AGRIF nests). Presentations are welcome on all aspects of the ocean variability influenced by these fine scales, for example

- Intrinsic variability forced by ocean mesoscale dynamics

- Variability of boundary currents and inter-basin exchanges

- Water mass formation and deep overflows

- Interactions between ocean dynamics and biogeochemistry

 

2) Understanding and modelling ocean-ice-atmosphere interactions, and their consequences for climate

This session will focus on coupled ocean-ice-atmosphere simulations and earth system models.

- Role of mesoscale dynamics in the coupled system

- Recent advances in high resolution coupled model simulations (e.g. HighResMip and Primavera projects)

- First studies of ocean characteristics and ocean variability in CMIP6 models

- What new strategies, based on high resolution coupled ocean-atmosphere models, can be proposed to force ocean models? The latter includes the use of atmospheric boundary layers models (e.g. cheapAML, Albatros/SIMBAD, Parameterizations of ocean mesoscale feedback on atmosphere).

 

3) Progresses in numerical modelling and model data analysis techniques

- Updates on the development of NEMO and on the use of NEMO4 in the different groups

- Presentation of new tools and new experience in analyzing large model datasets (PANGEO, python tools, cloud-based storage, etc.)

- Can we learn something new about our models (and hopefully the ocean, too) by applying data science methodologies such as machine learning and big data statistics?

  

4) Understanding and modelling the ocean mixed layer and its heterogeneity

This session focuses on processes and parameterizations involving the ocean surface mixed layer:

- ocean-ice-waves-atmosphere interactions in the polar ocean;

- heterogeneity of mixed layer processes in models and observations

- role of mesoscale and submesoscales on air-sea fluxes and ventilation at the mixed layer base.

This session will be held on wednesday 5th morning, as an introduction to a workshop of the MEDLEY project (MixED Layer hEterogeneitY) funded by JPI-Ocean and JPI-Climate. The workshop will take place wednesday afternoon.

 

 

Proposed discussion items

Ample time will be allocated for discussions during the meeting. The participants are invited to submit propositions for breakout groups for technical discussions (e.g., about the details of NEMO-based model configurations or analysis tools).
