Developing the Space Weather Modeling Framework

Abstract:


Space weather describes the interactions in the Sun-Earth system that 
affect human technologies and health, including damage to satellites, 
loss of communication, degraded accuracy of global positioning systems, 
safety of astronauts, air plane pilots and passengers flying along polar 
routes.

Modeling and eventually predicting space weather is therefore a 
practically important challenge.

The Center for Space Environment Modeling (CSEM) at the University of 
Michigan has been at the forefront of physics-based space weather 
modeling. Our group has developed the Space Weather Modeling Framework 
(SWMF) that integrates independently developed models into a high 
performance simulation tool. The SWMF models physics domains spanning 
from the solar corona and heliosphere to the magnetosphere, ionosphere 
and thermosphere of the Earth.

The SWMF can perform a realistic Sun-to-thermosphere simulation faster 
than real time on today's supercomputers.

I will describe the SWMF and some of the numerical techniques that 
enable it to achieve the required performance. In particular I plan to 
talk about a new scheme for modeling Hall MHD on block adaptive grids.
