Climate and Ocean -
Variability, Predictability, and Change

On 30^th September, CLIVAR held a teleconference to discuss the ongoing WCRP Implementation Plan and how CLIVAR as a community should respond and provide feedback.

The CLIVAR Tropical Basin Interaction RF held its monthly teleconference on 24^th September, chaired by Ingo Richter and Noel Keenlyside.

Upon invitation by the Executive Secretary of the North Pacific Marine Science Organization (PICES), CLIVAR joined the PICES-2020 Annual Meeting (virtual) as an observer. The theme of the meeting is “How does 30 years of research on changing North Pacific ecosystems inform the UN Decade of Ocean Science for Sustainable Development Goals (SDGs)?”.

CLIVAR participated in the Physical Oceanography and Climate (POC) Committee meetings, which was organized on September 28-29, 2020, and exchanged the opinions about future collaboration between PICES and CLIVAR.

IORP held its quarterly telecon on 21 September 2020. Emma Heslop from the Global Ocean Observing System (GOOS) was invited to introduce the GOOS’ ongoing effort in assessing the impacts of COVID-19 on global ocean observing networks, and share the experience in the Atlantic Ocean. 

The paper uses an unprecedented ensemble of regional climate model (RCM) projections over seven regional CORDEX domains to provide, for the first time, an RCM based global view of monsoon changes at various levels of increased greenhouse gas (GHG) forcing.

The International Project Offices (IPOs) and Joint Planning Staff (JPS) of WCRP held a teleconference on Sep. 9, 2020. The telecon focused on the discussion of the involvement of the IPOs in the WCRP restructuring process, as well as how to strengthen the communication between WCRP JSC and IPOs. Representatives from the WCRP JPS and project offices of CLIVAR, CliC, GEWEX, SPARC, CORDEX, CORA, S2S and YESS attended the meeting.

The CLIVAR Climate Dynamics Panel organized the routine telecom on 10^th August 2020. 

The ‘butterfly effect’ is used by climate scientists to refer to an infinitesimal random perturbation to an identical initial condition (for example, in surface temperatures) causing drastically different trajectories. A recent study published in Nature (Cai et al.

The call for nominations to CLIVAR panels is now open, with appointment starting in January 2021. Nominations can be submitted online via the nomination form, deadline for the submissions is 23^rd October, 2020. Detailed information about CLIVAR panels, including current activities and membership can be found on the CLIVAR Panels webpages.

The CLIVAR Pacific Region Panel had a one-hour telecon on 6 August 2020, which focused primarily on the discussion of the CLIVAR-endorsed observational project entitled ‘Enhancing the Chilean Climate Ocean Observing System (ECCOOS)’, followed by some other business items.
