Welcome to the US Climate Variability and Predictability Program

US CLIVAR Greenland Ice Sheet-Ocean Interactions Workshop Report

Front cover of a report

In June 2013, the US CLIVAR Greenland Ice Sheet-Ocean Interactions Working Group convened an international workshop in Beverly, Massachusetts, bringing together 90 scientists from oceanography, glaciology, atmospheric, paleo, and climate sciences to promote a deeper understanding of the physical processes involved in ice/ocean/atmosphere interactions in Greenland to enable improved modeling for more reliable projections of Greenland Ice Sheet mass changes and contributions to sea level.  The Report from the International Workshop on Understanding the Response of Greenland’s Marine-Terminating Glaciers to Oceanic and Atmospheric Forcing, now available online, summarizes presentations and discussions from eleven topical sessions and outlines an emerging research strategy for improving observations, process understanding, and modeling to make progress over the next decade on the question of how the ocean impacts Greenland’s glaciers.

Re-release of the US CLIVAR Hurricane Workshop Report

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 20th century to present and to quantify changes in the characteristics of tropical cyclones in a warming climate. 

Winter 2014 Edition of Variations

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 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.
