Modeling the natural world with Anthony Walker
During the workday, Anthony Walker spends considerable time designing models to advance our understanding of Earth’s biological systems. In the evenings and on weekends, he takes a more hands-on approach to the natural world, whether working in his garden or out kayaking on area waterways. The terrestrial ecosystem modeler has tackled a variety of tasks since arriving at Oak Ridge National Laboratory 4 years ago, including leading an international group of scientists exploring how forests respond to elevated levels of carbon dioxide (CO2).
Simulating Extreme Storms over the Alabama-Coosa-Tallapoosa River Basin
PMP is defined as the largest rainfall depth that could physically occur under a series of adverse atmospheric conditions. It is the design standard of highly important energy-water infrastructures such as dams and nuclear power plants. To understand how PMP may respond to projected future climate forcings, a physics-based numerical weather simulation model was used to estimate PMP across various durations and areas.
Salil Mahajan: Gaining Perspective on Climate Variability with High-Resolution Modeling
Simulating the global climate in high resolution at multiple scales will help answer questions about future global and regional climates. However, as performance expectations increase for Earth system models, so do computing challenges. Salil Mahajan, a computational climate scientist in the Computational Earth Sciences group at the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL), is tackling some of these challenges in high-performance computing for climate science.
Computer Science Meets Ecology: Hoffman Presents Research at Dagstuhl Seminar
Dr. Forrest M. Hoffman participated in the Dagstuhl Seminar, held February 26–March 1, in Wadern, Germany. Seminars at Dagstuhl bring together researchers of international standing and promote professional interaction as well as open discussion of leading research ideas and results. They are sponsored by the Schloss Dagstuhl–Leibniz Center for Informatics, a nonprofit center with the mission of furthering world-class research in computer science.
