How Is Computational Capability Pacing the Realistic Simulation of Earth's Climate System?
Jim Hack, NCAR
The simulation of weather, climate, and global change has been among the more visible "Grand Challenge" applications that have driven the investment in high-performance computing research and development over the past two decades. The simplest argument motivating exponential growth in computing capability is the need to integrate these models at much higher resolution with considerably more complex mathematical treatments of the climate system. This talk will examine the way in which advances in high-performance computing technology are pacing progress in our ability to realistically simulate global climate. The emphasis will be on resolving longstanding simulation biases in global models, many of which defy the application of brute-force technological solutions.
