The Second Report has been released. The Executive Summary is currently available in English; translated versions will be posted when they are available.

AGU 2019 session on ‘Earth’s energy imbalance and energy flows through the climate system’ was organized by Drs. Maria Hakuba, Seiji Kato, Matt Palmer, Tristan L’Ecuyer. Abstract submission deadline is July 31st.

Some CLIVAR members are organizing a session (A054) co-sponsored by WCRP on “Decadal Climate Variability- Mechanisms, Predictability and Prediction” at the AGU 2019 Fall Meeting, that could be of interest to you. Please consider submitting an abstract. The abstract submission deadline is Wednesday, 31 July. 

The paper provide an overview of the vital information relating to ocean observations that supports the science policy interface developed and provided by the Regular Process and detail the utility of the Regular Process in helping to guide planning for the activities of the United Nations (UN) Decade of Ocean Science for Sustainable Development.

The SWOT ‘Adopt-A-Crossover’ Consortium for a series of international in-situ campaigns has been endorsed by CLIVAR.

The Joint Scientific Committee (JSC) – the guiding body of the World Climate Research Programme (WCRP) – held its 40th annual session at the World Meteorological Organization headquarters in Geneva, Switzerland, from 6 th to 10 th May 10 2019.

The Sea Ice Prediction Network-SOUTH (SIPN-South) project has collected seasonal forecasts of Antarctic sea ice aligned with the Year Of Polar Predict

4 Chinese ocean scientists tragically passed away on 21st April 2019 during the Kingsbury Colombo Hotel explosion in Sri Lanka, while waiting to participate in the 'Joint Voyaging on East Indian Ocean’ which was initiated by SCSIO.

This second-generation CLIVAR Science Plan builds on the important legacy of CLIVAR emerging since its inception in 1992 and redirects the CLIVAR goals and priorities for the coming decade after consultation with scientists and stakeholders throughout the climate community.

Science Highlights

 Members from the CLIVAR Ocean Model Development Panel (OMDP) and collaborators summarized the new developments in ocean modeling since a similar OMDP review from 2010.

The El Niño-Southern Oscillation (ENSO) affects the rest of the world’s tropics by perturbing global atmosphere circulation, inducing anomalous Sea surface temperatures over the tropical Indian Ocean and Atlantic Ocean.  The associated wind variations in the Indian Ocean and in the equatorial and north tropical Atlantic in turn contribute to ENSO dynamics. In addition, the tropical interbasin linkages vary on decadal time scales. 

The scientific challenge is extreme due to the rich complexity of interactions and feedbacks between regional and global processes, each of which affects the global climate trajectory. Technical development, international coordination, and a close interaction between the science and stakeholder communities are also required.
