Observations and modeling of turbulence in the solar photosphere, chromosphere,and low corona
Session ID#: 250340
Session Description:
Magnetohydrodynamic turbulence is increasingly recognized as a key process driving coronal heating and solar wind acceleration. Till date, in-situ measurements have provided crucial insights into turbulent processes in the high corona and interplanetary medium, leaving the origin and injection of turbulence in the lower solar atmosphere poorly understood. The transition of turbulence across different regimes -- from the partially-ionized photosphere/chromosphere to the fully-ionized corona – remains a crucial, yet largely unquantified component of the overall energy transport and dissipation. Recent advances in high-resolution space-borne (e.g., SDO, IRIS, Hinode, SolO) and ground-based (e.g., SST, BBSO, DKIST) instrumentation offer a unique window to investigate these processes and provide important constraints for models. This session invites contributions that address the onset and evolution of turbulence between the photosphere and the lower solar atmosphere, its observable signatures, and implications for coronal and solar wind models. We welcome abstracts from both observational and theoretical perspectives.
