Abstract

Upgrade the ocean-wave coupling representation by including recent works on enhanced ocean mixing due to breaking waves

Description

This action is an activity of IMMERSE Task5.2 and focus on the upgrade the ocean-wave coupling representation by including recent works on enhanced ocean mixing due to breaking waves (Janssen et al 2014, Alari et al. 2016, and outcomes from WAVE2NEMO and OWAIRS CMEMS service evolution projects).
This is the first step to be achieved by end 2019. The final aim is to include an additional wave coupling development by mid 2020, which consists in modified vertical mixing due to breaking waves: the energy flux explicitly evaluated by a wave model (through the dissipation term in the wave energy balance equation) will be used as a new source of vertical mixing scheme.

Implementation

A branch will be created gathering recent works on enhanced ocean mixing due to breaking waves.
The implementation then will be finalized (by mid 2020) by adding a new source term in the vertical mixing as an energy flux explicitly evaluated by a wave model.

Reference manual and web pages updates

Using part 1 and 2, define the summary of changes to be done in reference manuals (tex files), guide (rst files) and in the content of web pages.

Once the PI has completed this section, he should send a mail to the previewer(s) asking them to preview the work within two weeks.

During 2019 the following activities have been carried out:

  • the NEMO-wave code development provided in the context of the WAVE2NEMO CMEMS Service Evolution Project and related to modified GLS routine (including enhanced mixing due to breaking waves in turbulent kinetic energy surface boundary conditions) has been gathered, checked and an initial work has been performed in order to align with NEMO v4.0.1
  • The NEMO-wave code developments provided in the context of Couvelard et al., 2019 paper (Madec developments) have been gathered and a check is ongoing on the TKE routine modifications due to the contribution of the Stokes Drift and to the injection of TKE at the surface due to a wave breaking dissipation term

Due to the need of better investigate and include the work of Couvelard et al. (2019), which was not foreseen when writing IMMERSE proposal, this activity will be finalized in February 2020.
