The US Repeat Hydrography CO₂/Tracer Program, having recently completed a decade of full-depth surveys of the world’s ocean basins, has compiled a report summarizing programmatic and scientific achievements. As a contributor to the international Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP), the US program has advanced understanding of the role of the ocean in climate change, carbon cycling, and biogeochemical responses. The report highlights key scientific discoveries and presents future science and monitoring objectives.

The 95th Annual Meeting of the American Meteorlogical Society will be held on January 4-8, 2015 in Phoenix, Arizona. The theme for the meeting is “Fulfilling the Vision of Weather, Water, and Climate Information for Every Need, Time, and Place”. 

Check out our compiled list of sessions relevant to the CLIVAR community. 

Message on behalf of Erica Key, National Science Foundation:

Now available online is the sixth annual report for the US AMOC Science Team. This report features progress made in the past year on the main objectives of the program, identifies any programmatic gaps, and makes recommendations on near-term research priorities for the program. Findings and recommendations from an external review process conducted in 2012-2013 and highlights from the US AMOC/UK Rapid international meeting are also featured.

Following on the release of the new Science Plan, the upcoming 2014 US CLIVAR Summit in Denver will review progress, identify opportunities, and develop strategies to advance US CLIVAR goals. The meeting will have a particular focus on benchmarks and metrics for evaluating improvements in monitoring and analysis, model development, and prediction. To learn more about the Summit, check out the agenda. (Please note this is an invite only meeting.)

The US CLIVAR Working Group on Extremes releases its summary report of the 2013 workshop on Analyses, Dynamics, and Modeling of Large-Scale Meteorological Patterns Associated with Extreme Temperature and Precipitation Events. The report synthesizes the findings and discussion of the 62 participating scientists who explored data issues, statistical and dynamical methods, and modeling approaches to enable improved analysis and simulation of short-term (5 days or less) extreme events in North America. It also presents a clear set of recommendations to accelerate progress in this important field of research.

Check out our latest edition of Variations with invited articles on Greenland’s glaciers and their response to forcing by the ocean and atmosphere.  Understanding how the Greenland ice sheet behaves in a changing climate is essential to predicting future sea level rise and the effect of changing fresh water fluxes on the circulation of the North Atlantic Ocean and its related climate impacts. 

The 2014 US AMOC Science Team Meeting to be held in Seattle, Washington, September 9-11.  The bi-annual meeting is open to all US and international scientists interested in learning about and sharing research on the Atlantic Meridional Overturning Circulation, including its linkages with climate variability and change. Abstracts are no longer being accepted for this meeting. Please visit the meeting site for further details. 

Download the Report from the International Workshop on Understanding the Response of Greenland’s Marine-Terminating Glaciers to Oceanic and Atmospheric Forcing, summarizing a June 2013 workshop and an emerging research strategy for improving observations, process understanding, and modeling to make progress over the next decade on the question of how ocean impacts Greenland's glaciers.

US CLIVAR reissues the Hurricane Workshop Report in an updated format.  The report summarizes the June 2013 workshop presentations and synthesizes discussion on the analyses of climate model experiments coordinated by the US CLIVAR Hurricane Working Group to improve understanding of interannual variability and trends in tropical cyclone activity from the beginning of the 20^th century to present and to quantify changes in the characteristics of tropical cyclones in a warming climate.
