Video: How Exascale will Power Climate Research

In this video, Climate modelers James J. Hack of Oak Ridge National Laboratory and Mark Taylor of Los Alamos National Laboratory discuss how Exascale computing capabilities will improve climate predictions. In the meantime, scientists must figure out how to refine their models to make full use of all that power.

With exascale computing, climate-change models can start to resolve physical properties like ocean eddies – and potentially resolve hurricanes,” said Ben Kirtman, professor of meteorology and physical oceanography at the University of Miami. He and colleagues are studying eddies and how they transport heat from the tropics to the United States. These eddies maintain the Gulf Stream. “Until we get exascale,” he says, “we need lots of years of simulations” to model how these eddies affect heat transfer.
