Strategy and Evolution of CLIVAR


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

CLIVAR – A Global View



Questions, Issues:o What research should be the focus of an “ocean-

atmosphere” project?

Strategy and Evolution of CLIVAR @ SSG-18

Grand Challenges as “banners” for WCRP science: o How are they defined? o Which ones should we propose?

o Is it time to “downsize” CLIVAR? If so, where do some

current (broader) activities fit in the restructured WCRP?

o Is it time to change the name of CLIVAR? Pros and cons?

o How to ensure needed interactions/partnerships (across

WCRP, IGBP, WWRP, ESSP, etc.) in a restructured WCRP?o How to ensure critical and effective interfaces for regional

programs (e.g., VACS, VAMOS, AAMP, etc.)?


Seven CLIVAR Research Imperatives• Top priorities of CLIVAR panels and working groups,

with metrics and specific deliverables, for ~5 years• Developed and evolving around several criteria; scientific importance; opportunity to make considerable progress; benefit from international coordination• Imperatives map across: CLIVAR panels and working groups WCRP and other international research programs• They help inform ongoing discussion on

future evolution of ocean-atmosphere activity in WCRP


CLIVAR/WCRP Imperatives`3xzu • Anthropogenic Climate Change

• Natural variability versus forced change• Climate sensitivity and feedbacks• Regional phenomena (e.g., ENSO, AMOC, …)• Extremes• CMIP#• Climate Engineering (GEOENGINEERING)

• Decadal Variability, Predictability and Prediction• Determine predictability• Mechanisms of variability (AMO, PDV, …)• Role of oceans• Adequacy of observing system• Coupled Initialization• Quantifying prediction uncertainty• Building pan-WCRP links

• Intra-to-Seasonal Variability, Predictability and Prediction• Monsoons (and ENSO, TAV, …)• ISV/MJO• Quantifying prediction uncertainty• Building pan-WCRP and WWRP links• CHFP


CLIVAR/WCRP Imperatives• Improved Atmosphere and Ocean Components of ESMs

• Analysis and Evaluation• “Climate Process Teams” (process studies)• Building links pan-WCRP and IGBP• Model-Data comparisons

• Capacity Building• Summer schools and topical workshops• Expert training• Call for panel membership

• Data Synthesis and Analysis• Ocean• Coupled Data Assimilation Systems• Links – carbon, biogeochemistry, marine-ecosystems

• Ocean Observing System• Development, implementation and system design• Advocacy for sustained observations• IGBP links for Carbon, Biogeochemistry, Ecosystems

Task Force on Decadal Predictability


SSG-18: Much CLIVAR science falls under “ocean-atmosphere” •

Ocean basin panels, GSOP, WGOMD Ocean observing system (partnership with GOOS/IOC,

JCOMM, etc.) Decadal prediction of coupled system (WGDP)

given the dominant role of oceans on these time scales

But some CLIVAR activities are broader and do not, including existing interactions with GEWEX, SPARC, CLIC, …

extremes; annular modes; sea level rise; etc. earth system modeling & seasonal pred. (WGCM, WGSIP) monsoons (e.g. parts of VAMOS, AAMP, VACS) should be

redefined with GEWEX and WCRP applications

Strategy and Evolution of CLIVAR


What Constitutes Grand Challenge? o A strong Grand Challenge is both highly specific and highly focused

identifying a specific barrier preventing progress in a critical area of climate science.

o This focus enables the development of targeted research efforts with the likelihood of significant progress over 5-10 years, even if its ultimate success is uncertain.

o It should thus enable the implementation of effective and measurable performance metrics.

o By being transformative, a Grand Challenge should bring the best minds to the table (voluntarily), building and strengthening communities of innovators that are collaborative, perhaps also extending beyond “in- house expertise”.

o It can capture the public’s imagination: teams of world-leading scientists working to solve pressing challenges can offer compelling storylines to capture the interest of media and the public.

Develop and apply knowledge to manage risks transition to a secure future of equitable and integrated environmental, social, and economic well-being.

“Future Earth” Objectives

Coordinate and focus international scientific research to address the Grand Challenges arising from the ICSU Visioning and Belmont Forum processes in order to use human and financial resources efficiently so as to support efforts of international science to understand environmental change and to provide solutions to society;

Build on and continue successful international collaborative projects that are addressing critical global change problems

Engage a new generation of diverse researchers from all regions in the social, economic, natural, health, and engineering sciences in global sustainability research to ensure the future success of research efforts

“Future Earth” Objectives

Strategically integrate social-, economical, engineering and natural sciences and in the pursuit of solutions to growing problems of global environmental change and sustainable development

Foster a major step-change not only in scientific endeavor, but also in bridging science-policy-practice, science in support of development, service provisioning, communications, and capacity development.
