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 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.

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. 

Check out our latest edition of Variations with invited articles on the Large-Scale Meteorological Patterns (LSMPs) associated with extremes in temperature and precipitation in North America.  Diagnosing the relationship between LSMPs and extremes provides a means for evaluating climate model simulations of the variability of extremes under a changing climate.

The US CLIVAR Scientific Steering Committee seeks qualified individuals to serve on its three subsidiary panels beginning in 2014.  These Panels formulate science goals and implementation strategies, catalyze and coordinate activities, and work with agencies and international partners to advance the progress of the climate research community.  It is a particularly exciting time to join the Panels, as they embark on planning activities to address the goals and research challenges articulated in the recently published US CLIVAR Science Plan.

Consider nominating yourself or a colleague to serve.  See the Call for New Panelists on our website for information on the expertise sought and the link to the online nomination form.  Deadline for nominating is March 21.  Decisions will be made in April.

The new US CLIVAR Science Plan is now available outlining the research goals and strategies for the next 15 years of the program.  Specifically, the Plan is intended to: 1) update the goals and priorities of US CLIVAR based on achievements to date; 2) articulate the expansion of core research to target specific research challenges; 3) emphasize strengthened ties to the broader Earth Sciences community and relevance to societal impacts; 4) bolster research funding commitments by US agencies to achieve their mission objectives; and 5) articulate the envisioned collaborations with other US and international research programs.

The US CLIVAR Hurricane Working Group was formed to coordinate efforts to produce a set of model experiments designed to improve understanding of the variability of tropical cyclone formation in climate models.  The WG hosted a workshop this summer at GFDL that included presentations by US and international scientists.  The Hurricane Workshop Report, summarizing 30 presentations over the 2.5 day event, is now available online

The theme for the Fall 2013 edition of Variations is Hurricane/Tropical Cyclone frequency and intensity.  The edition contains articles from members of the US CLIVAR Hurricane Working Group including findings presented at the recent workshop at GFDL.
