[Executive Summary: January 2014]

The Coordinated Ocean Wave Climate Project (COWCLIP) review meeting was held on November 1-2, 2013 at the Fairmont Banff Springs Hotel, Banff, Canada, with the support of the Joint Technical Commission for Oceanography and Marine Meteorology of the World Meteorological Organization and the Intergovernmental Oceanographic Commission of UNESCO (JCOMM). The meeting aimed to review the status of COWCLIP and the research being carried out within its community, assess the continued need for COWCLIP, clarify COWCLIP\'s mission and objectives, and reassess the organizational structure of the COWCLIP Working Group. It was attended by twenty-one researchers from twelve countries.

The meeting was opened with a brief overview of COWCLIP. This outlined the objectives and scope of COWCLIP, which span:

• Global projections of wind-wave climate under future climate scenarios
• Regional projections of wind-wave climate under future climate scenarios
• Coupled wind-wave-climate modeling
• Historical wave climate variability and change.

Achievements since the 2011 workshop at which the COWCLIP working group was formed were reviewed, and the aims of the meeting outlined.

On the first day of the meeting, attendees were invited to present brief updates on progress and future planned research activities that overlap with the interests of the COWCLIP, and 9 contributing research groups provided updates. This was followed by a broad discussion which covered several areas, including:

1. Have the CMIP5 experiments met the wave community needs? What could be improved for CMIP6? COWCLIP recommendations for CLIVAR
2. Climate-wave model coupling
3. Assessing skill of GCMs for wave climate studies
4. Regional studies
5. Extremes
6. Forcing conditions other than wind (e.g., ice coverage, SST, tropical cylones, etc).

The second and final day of the meeting provided the opportunity for targeted discussion on how COWCLIP should proceed into the future. The aim of COWCLIP was clarified; to raise the profile of wind-waves as a variable in the global climate system - both to foster and support determination of:

• the effects of climate variability and change on the wave climate, and
• the feedback influences of waves on the coupled ocean-atmosphere climate system.

To maximize exposure of the activities of the COWCLIP working group, it was agreed that the group should aim to integrate with other programs/working groups for which overlap exists. Much work was identified to progress the COWCLIP aims, and a more defined organizational structure was agreed to meet these demands. The meeting was closed with agreement of success.

[General Information: February 2013]

An open invitation COWCLIP review meeting is scheduled to align with the 13th International Workshop on Wave Hindcasting and Forecasting (http://www.waveworkshop.org). The Wave Workshop is to be held at the Fairmont, Banff Springs, Banff, Alberta, Canada (http://www.fairmont.com/banff-springs/) during the week 27th October – 1st November, 2013. The COWCLIP review meeting will be held on the following Saturday (2nd November) at that location with the support of JCOMM.

A COWCLIP related wave climate session is proposed for the Wave Workshop, and we invite abstracts across the following themes for this session:

1. Historical wave climate variability and change
2. Regional and global wind-wave climate projections
3. The role of wind-waves in the coupled climate system.

• Assess progress of the COWCLIP project against the objectives agreed at the Geneva workshop (see http://www.jcomm.info/cowclip)
• Review future activities for COWCLIP
