CLIVAR (Climate Variability and Predictability)
CLIVAR is an interdisciplinary research effort within the World Climate Research Programme (WCRP) focusing on the variability and predictability of the slowly varying components of the climate system.
CLIVAR investigates the physical and dynamical processes in the climate system that occur on seasonal, interannual, decadal and centennial time-scales.

CLIVAR CLIVAR MissionMission•To observe, simulate and predict To observe, simulate and predict Earth’s climate system, with Earth’s climate system, with focus on ocean-atmosphere focus on ocean-atmosphere interactions, enabling better interactions, enabling better understanding of climate understanding of climate variability, predictability and variability, predictability and change, to the benefit of change, to the benefit of society and the environment in society and the environment in which we live.which we live.

CLIVAR Goals and CLIVAR Goals and ObjectivesObjectives• Understand the physical processes responsible for Understand the physical processes responsible for climate variability and predictability on climate variability and predictability on seasonal, interannual, decadal, and centennial seasonal, interannual, decadal, and centennial time-scales …time-scales …
• Extend the range and accuracy of Extend the range and accuracy of seasonal to seasonal to interannual climate prediction …interannual climate prediction …
• Extend the record of climate variability …Extend the record of climate variability …
• Understand, predict and detect Understand, predict and detect the anthropogenic the anthropogenic modificationmodification of the natural climate signal. of the natural climate signal.
of the Earth System• Seamless Prediction of the Total Physical Climate
System from Weeks Through Decades• Synthesizes Ongoing Observational and
Modeling Activities of the all Relevant WCRP Components
• Central Themes include:– Describe Structure and Variability of the Total Climate
System Through Modeling and Observational Studies– Assess the Predictability of the Total Climate System– Understand Mechanisms and Uncertainty of Regional
Climate Change Prediction
• CLIVAR has the central role in delivery of COPES• COPES Project Office asnd website
CLIVAR Assessment (SSG-13)
• Organised by:– CLIVAR streams (GOALS, DecCen, ACC) referenced to
the Science & Implementation Plans and ToRs of Panels & WGs
– Unifying streams of “Data” & “Modelling”– Overall programme structure & the ICPO
CLIVAR - Principal Research Areas
CLIVAR Assessment (SSG-13)
• Organised by:– CLIVAR streams (GOALS, DecCen, ACC) referenced to
the Science & Implementation Plans and ToRs of Panels & WGs
– Unifying streams of “Data” & “Modelling”– Overall programme structure & the ICPO
• Team of 6 assessors and SSG liaisons• Inputs
– Panel & Working Group responses to questionnaire– CLIVAR web pages & documents– Reviewer/Panel & WG interactions– CLIVAR Conference
• Written & oral reports to CLIVAR SSG-13• Subsequent analysis of outcomes
Outcomes of the CLIVAR Conference and Assessment:
Key areas for science development• Regional analysis of global model outputs and
in particular ocean reanalysis activity & related data management issues
• Strengthen CLIVAR activity in ACC• Links between process studies & model improvement• Cross CLIVAR effort on climate indices• Ocean observing strategy including hydrography &
carbon links• Pan WCRP monsoon activity (with GEWEX)• Applications of CLIVAR science
Key outcomes of the CLIVAR Conference and Assessment:
Management Foci• Continued programme assessment
• Annual workshops against the 4 science foci in turn (ENSO, ACC, Monsoons, Decadal/THC) and (additionally) the ocean’s role in climate
• Overall CLIVAR structure• CLIVAR’s global<=>regional panel interactions• CLIVAR visibility and networking• Overall CLIVAR data and information management • Web site development• New structure for the ICPO
CLIVAR assessment: Particular issues for WGOMD
SSG-13:• Recognised the WGOMD role in performing the WGOMD
assessment of ocean model performance in ocean-only experiments.
• However it felt it would also be important for WGOMD to focus on the role of the ocean as a component of the coupled climate system and on how improvements in ocean models impact on coupled models,
• Requested WGOMD (with WGCM and WGSIP) to work with GSOP on how they will interact in the future, in particular on what observation simulation experiments are feasible to give guidance on observation system design.
• Requested efforts be made to strengthening of the links between between WGOMD and the CLIVAR ocean basin panels, in particular in regional assessment of WGOMD global model coordinated experiments
Key issues of the CLIVAR Conference and Assessment:
Summary Response• On an annual basis CLIVAR progress will be assessed
against four major global themes: ENSO, Monsoons, THC/Decadal and ACC. Each year a topical workshop will be held for one of the four themes.
• ACC representation to be increased on SSG• Global perspective/framework to be provided by
GSOP, WGSIP, WGCM, WGOMD, and CCD• Global to regional perspective provided by Monsoon
Panels for VAMOS, VACS, and AAMP and Ocean Basin Panels for Atlantic, Pacific, Indian, and Southern Oceans
• WGOMD to consider strengthening assessment of ocean models in coupled framework, links to GSOP (especially in respect of OSSEs) and interactions with ocean basin panels
CLIVAR SSG 14 (Buenos Aires, 19-22 April 2006)
• Review progress in developing global-regional links• Consider roadmap for CLIVAR input to COPES• Assess progress against the key science foci• Review CLIVAR’s efforts in the role of the oceans in climate
as an additional science focus point• Consider strategies for:
– developing CLIVAR’s key science foci– strengthening regional-global links– Pan-WCRP monsoon activity and CLIVAR-GEWEX intersection– CLIVAR data management …
• Review Panel/WG developments overall• Consider CLIVAR visibility and outreach• Review overall CLIVAR structure• Draft agenda and detailed information on format and
reporting to be sent out soon. Inputs will also be used for reporting to JSC XVII (Pune, 6-11 March 2006)
