HAO Workshop “Model Coupling and Data Driven Simulations of Solar Eruptions” – Mesa Lab of NCAR, Boulder, August 13–16, 2018: Meeting Registration Deadline June 1 2018May 15, 2018, from Richard Morton
Registration at www2.hao.ucar.edu/Workshop/ModelCoupling-2018
HAO is hosting a workshop focusing on model coupling and data driven numerical simulations with the goal to improve the realism of modeling active region flux emergence and work towards simulating realistic solar eruptive events. Significant progress has been made in recent years in both of these areas. Near surface layer radiation MHD simulations of active region formation driven by lower boundary condition of emerging flux from a solar convective dynamo simulation are able to model sunspot and active region formation with realistic properties of the observed solar active regions. Methods of using observed time sequences of vector magnetograms to drive simulations of realistic solar eruptive events in the corona are being explored and developed. This workshop will bring together modelers and observers working in these areas to review recent results, discuss methodologies and future directions. The following are some of the questions to be addressed:
- What are the challenges of modeling realistic active region formation? How can model coupling be used to bridge the wide range of temporal and spatial scales (from global scale dynamo generation of active region flux to near surface layer fine scale evolution of sunspot formation) and the different physical regimes the problem encompasses?
- How coupled models and simulations can help us interpret surface observations of active region evolution in terms of the subsurface structure of emerging flux, and deriving the boundary driving condition for coronal models of solar eruption?
- Are photospheric observations of vector magnetic field evolution adequate to drive MHD models to be able to realistically model the magnetic field evolution of eruptive events? What additional observational data can be used?
- Many current CME simulations use ad-hoc boundary-driving to numerically construct a pre-eruptive coronal configuration and trigger its eruption. What are the adequate boundary conditions for such simulations, especially for the imposed electric fields? How can information derived from vector magnetic data or flux-emergence simulations be used to further increase their realism?
All interested in this area of research are welcome to participate in this workshop and present their work. The format of the workshop will be informal oral presentations and open discussion sessions. We hope to have useful and effective discussions on the above topics during the workshop. Some travel support is available for graduate student participants.
