CLIVAR/CliC/SCAR Southern Ocean Panelreport to CLIVAR SSG

CLIVAR SSG actions wrt SOP (in brief)

1. CLIVAR and CliC SSGs should discuss and ratify full SOP cosponsorship, selection of membership by both SSGs.

2. Biogeochemical interests – how to liase with ocean acidification, carbon, nutrient organizations (Future Earth?)

3. Meeting and workshop support: SOP-10 in Qingdao, SOOS Air-sea flux workshop

4. Guidance in revising terms of reference5. CLIVAR Research Foci: SOP strong involvement in

Decadal, Upwelling, Sea Level, and Heat6. WOCE Grand Challenges: SOP strong involvement in

Cryosphere, and also Clouds….

Interaction with other panels

CliC: Joint sponsorship of projects and workshops. Proposed: CLIVAR and CliC SSGs to jointly appoint members, ensuring seamless activity; SOP to respond to both CLIVAR and CliC science priorities; concern about multiple, excess reporting.

SCAR: cross-membership, involvement of SOP in SCAR’s ocean-relevant activities? Not active, not working.

SOOS: cross-membership; advising from SOOS at each SOP; recommendations from SOP back to SOOS. Active and working.

CLIVAR OMDP: Maintain existing strong relationship. Active and working.

Begin relationships with biogeochemical panels – Future Earth, etc? (acidification, nutrients, productivity, upwelling). Where to go with this?

Membership and chairmanship issues 1SOP will be a committee of both CLIVAR and CliC

from henceforth. CLIVAR and CliC SSGs will jointly appoint SOP

members from henceforth, based on discussion with Krinner this week. CLIVAR and CliC SSGs should discuss and ratify this change.

Need minimum of 2 cryosphere members (CliC side) (H. Hellmer)

Need atmospheric scientist (currently no one)Need balance of modeling/observational expertise

(currently good)Need SCAR member (J. Shi)Need SOOS member (A. Naveira-Garabato)Need balance of countries (currently OK)

Membership and chairmanship issues 2

2-year length of term is too short given that SOP meetings are routinely 1.5 to 2 years apart. Hence many members roll over to 4 year total.

Recommend 3 or 4 year terms at outset.

When do we start consideration of new or roll-over membership?2014 (4, including co-chair), 2015 (2), 2016 (6)

Consider new modeling co-chair if M. England joins Climate Dyn. Panel. Could be someone who is strongly associated with CliC (cryosphere modeler)

SOP National Representatives

Southern Ocean national representatives act as contact points and keep the panel and SO community appraised of their countries' activities in the SO region. If you would like to act as a national representative for your country please contact Nico Caltabiano. The following countries have national representatives:

Argentina - Alejandro Bianchi Australia - Steve Rintoul Belgium - Hugues Goosse Brazil - Rodrigo Kerr* Chile - Dante Figueroa China – Jiuxin Shi* Finland - Aike Beckmann France - Sabrina Speich

Germany - Hartmut Hellmer Italy - Enrico Zambianchi Japan – Katsuro Katsumata* New Zealand - Mike Williams Norway - Svein Osterhus Russia - Alexander Klepikov South Africa – Isabelle Ansorge* Spain - Damià Gomis United Kingdom -

* 11 July 2014 updated

What is the role of this list? We need this national input, but the list is not the most helpful. Best input is from members of SOP regarding their own country, but not all countries are represented.

Meeting plans and budget requests

SOP-10 meeting at CLIVAR Open Science Conference in Qingdao. Will need support for panel.SOP host: Jiuxin Shi (SOP member; SCAR SSG)Will propose specific topics for Southern Ocean focus,

advertise with CliC, SOOS, SCAR communitiesSouthern Ocean model intercomparison experiments

(wind perturbation, meltwater perturbation)Dense water flux estimates

Attendance at SCAR and CliC meetings: budget from WCRP?

WorkshopsSOP endorsementSOOS workshop on Southern Ocean Air-Sea Fluxes

(early 2015; Gille et al.; Naveira-Garabato SOP rep.). Request for WCRP/CLIVAR financial support.

Ice shelf modeling with CliC (D. Holland) – will follow up

Carbon, Heat and Nutrients” prior to Fall 2014 AGU mtg. with significant US SOWG leadership and input (J. Russell)

Terms of Reference for SOP - old1.     Design a strategy to assess climate variability and predictability of

the coupled ocean-atmosphere-ice system in the Southern Ocean region.

2.     Engage and interact with the Southern Ocean Observing System (SOOS) programme on Southern Ocean sustained observations and model experiments needed to meet the objectives of CLIVAR, CliC, SOOS and SCAR.

3.     Work in concert with relevant CLIVAR panels (e.g. regional panels, numerical experimentation groups), ACSYS/CliC Panels (DMIP, OPP, NEG) and other groups (e.g. Ocean Observation Panel for Climate, Argo Science Team) to integrate Southern Ocean observations with those in neighboring regions to ensure the objectives of CLIVAR/CliC/SCAR are met and resources are used efficiently.

4.     Enhance interaction between the meteorology, oceanography, cryosphere, biogeochemistry and paleoclimate communities with an interest in the climate variability of the Southern Ocean region.

5.     Serve as a forum for the discussion and communication of scientific advances in the understanding of climate variability and change in the Southern Ocean region.

6.     Work with the CLIVAR, CliC, SCAR, SOOS and WCRP Data Council data systems on issues related to distribution and archiving of Southern Ocean observations.

7.     Advise the CLIVAR, CliC, SOOS and SCAR SSGs on progress achieved towards implementation.

Terms of Reference for SOP – redrafting in progress with V. Detemmerman

1. Define the tools required to assess climate variability, climate change and climate predictability of the ocean-atmosphere-ice system in the Southern Ocean region.

2. Design a strategy to implement these methods, spanning observations, models, experiments and process studies.

3. Provide scientific and technical input into this implementation, collaborating as required with other relevant programs, including the Southern Ocean Observing System (SOOS).

4. Monitor and evaluate progress of this implementation.5. Enhance interaction between the meteorology, oceanography,

cryosphere, biogeochemistry and paleoclimate communities with an interest in the climate of the Southern Ocean region.

6. Serve as a forum for the discussion and communication of scientific advances in the understanding of climate variability and change in the Southern Ocean region.

CLIVAR Research Foci – mapping to SOP

CLIVAR Research Foci Southern Ocean Panel relevance?

Monsoon systems None based on R.F. prospectus/discussion

Decadal variability and predictability of ocean and climate variability

Large interest: mid-latitude modes. Ensure SOP representation in membership.

Science Underpinning the Prediction and Attribution of Extreme Events

Overlap is indirect. (ice shelf breakup)

Marine biophysical interactions and dynamics of upwelling systems

Large interest that needs to be conveyed: S.O. upwelling system has large global impacts, and SOP includes acidification. Ensure SOP representation in membership.

Dynamics of regional sea level variability

Large interest: ice sheet mass balance, freshwater and heat inputs. Ensure SOP representation in membership.

Consistency between planetary heat balance and ocean heat storage

Large overlap, but S.O. not yet in outlines. Ensure SOP representation in membership.

CLIVAR Research Foci – mapping to SOP

Missing research focus? Mid- and high-latitude climate interactions

Could cover the (NH & SH) mid-latitude jets, ocean-sea-ice interactions, mid- to high-latitude ocean variability and trends, impacts of vacillations in the jets on regional climate and ocean properties, impacts of the jets on drought and climate extremes, climate over the Arctic and Antarctic. (M. England)
