CRD’s Michael Wehner Gives Presentation at Climate Workshop

July 1, 2005

Michael Wehner of CRD’s Scientific Computing Group was selected to give a presentation at a meeting of the Climate Change Working Group at the Tenth Annual CCSM Workshop held June 21-23 in Breckenridge, Colo.

The workshop is held annually for the Community Climate System Model (CCSM) project, which has been developed under the NSF’s and DOE’s sponsorship at NCAR, with the National Oceanic and Atmospheric Administration (NOAA), and the National Aeronautics and Space Administration (NASA) as part of the U.S. Global Change Research Program and the U.S. Climate Change Science Program. This year's workshop theme was “Crosscutting Science Using CCSM.”

Wehner’s talk was on “Changes in Daily Surface Air Temperature and Precipitation Extremes in the IPCC AR4.” Last year, Wehner received an NSF grant to characterize the ability of coupled climate models to simulate extreme weather events. The ability of these models to accurately simulate historical climate changes in the twentieth century will determine the credibility of their predictions of climate change during the twenty-first century and beyond.

Wehner’s grant was funded as part of the U.S. Climate Variability and Predictability (CLIVAR) project. A report summarizing aspects of this work will be furnished to the lead authors of the relevant chapters for the Intergovernmental Panel on Climate Change’s Assessment Report Four (IPCC AR4), a comprehensive review of current knowledge about climate change, which will be published in 2007.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
