SH12A:
Advances in Observations, Data-Constrained Modeling, and Predictions of Solar Activity from the Deep Interior to the Corona II

Submit an Abstract to this Session



Session ID#: 31307

Session Description:
Solar activity is a manifestation of magnetic self-organization processes that involve complex dynamical coupling of various layers of the Sun acting over a broad range of spatial and temporal scales. Recent advances in vector magnetic field measurements provide important clues to both the dynamo processes in the interior and the eruption processes in the corona. With the rapid increase in solar data and capability of MHD numerical models of the solar convection zone we are developing the ability to forecast the level of the next sunspot cycle. Synergy of observational, theoretical, and modeling efforts is a key to understanding solar activity variation, dynamics, and evolution and to developing reliable physics-based forecasts of long-term solar cycles and short-term activity manifestations, "seasons of solar activity", such as periods of enhanced flaring and CME activity. The session welcomes observers, modelers, and theoreticians to share their results and ideas and to discuss current challenges.
