Objectives:

Understanding the relevance of Atmosphere-Wave-Ocean exchanges processes and their roles in driving the ocean circulation at both coastal and global scales; identify required actions and models developments. In particular the working group will explore the way in which surface gravity waves can influence the ocean circulation. Coordinate actions with other groups/projects on similar goals: MyOCean, MyWave, etc.. Among the many processes occurring at the interface between the atmosphere and the ocean the group decided to explore in particular 7 different mechanism through which surface gravity waves can influence the ocean circulation:

  1. Computation of the Stokes drift currents to be coupled with the ocean hydrodynamics;
  2. Enhancement of upper ocean mixing through the wave-induced mixing by breaking and non-breaking waves;
  3. Modification of the wind stress due to surface roughness;
  4. Modification of the ocean hydrodynamics through large scale wave-current interaction introducing source and sink terms deriving from wave induced motion;
  5. Modification of the bottom roughness and thus the bottom shear stress;
  6. Radiation stresses effects in shallow waters;
  7. SeaIce? – Wave interaction.

Agenda:

  • A one-page document containing the list of principal processes through which waves can influence the ocean circulation has been distributed (see attachments)
  • A detailed document on the WAVE WG activities has been completed by the member of the consortium (see attachments)
  • The wave-current working group has been enlarged also to experts external to the NEMO consortium
  • The experts have been contacted sending them the one-page document circulated and asking their availability to take part in the working group
  • A 2-day meeting on atmo-wave-ocean current interactions has been carried out in May 2014 at ECMWF (Reading) with the participation of internal members and external experts. The first day meeting focused on the scientific approach, while during the second day the technical implementation of waves effects in NEMO has been discussed. The WG identified, as a first step development, a set of large scale wave effects to be implemented. Some technical issues have been identified with respect to a development branch created implementing the work done by ECMWF. In 2015 the identified issues will be implemented by the WG and a proper configuration will be created to test the developments. Time will be dedicated to start discussing the second phase development identifying the coastal processes to be implemented
  • Minutes of the meeting and a document that summarizes the discussions and provides information on future actions have been distributed (see attachments)
  • A technical document that describes the ECMWF branch created after the wave-current interaction meeting (Branch 2014/dev_r4642_WavesWG #1323) with comments and issues on the technical implementation has been created and distributed (see attached file)
  • The work done by the WAVE WG has been presented to the NEMO system team and the actions identified by the WG and the developments to be implemented in the code have been discussed
  • The work plan proposed has been accepted by the System Team and it has been also decided that the technical implementation must be carried out within the Wave-WG
  • A new branch has been created by INGV (branches/2014/dev_r4822_INGV_WAVE #1404) starting implementing the actions that have been identified (see attachments)
  • The work done by the WAVE WG has been presented during the Developer's Committee Meeting in December 2014. Presentation is included in the attached files.
  • The activities done by the WAVE WG in the first month of 2015 have been presented during the Developer's Committee Meeting in June 2015. Presentation is included in the attached files.
  • A report on activities carried out by the WAVE WG in 2015 and plans for next year are included in the attached files (now in draft version).
  • The activities carried out by the WAVE WG during 2015 have been presented during the Developer's Committee Meeting in January 2016 (Exeter). Presentation is included in the attached files.

The experts have been contacted sending them the one-page document circulated and asking their availability to take part in the working group

  • A half-day WAVE-WG meeting has been carried out in January 2017 in Grenoble with the participation of internal members and external experts. The meeting followed a half-day workshop during the DRAKKAR meeting on "Ocean wave model coupling" which has been the basis for the discussions of the WAVE WG meeting (http://meom-group.github.io/drakkar-meeting/). Minutes of the meeting are attached.
  • A meeting has been carried out in September 2017 in Liverpool during the Wave Workshop with the participation of internal members and external experts. Minutes of the meeting are attached.
