Description

The chromosphere is one of the least understood layers of the solar atmosphere, being dominated by ubiquitous, very dynamic fine structures. We here report on high-resolution, 3D, MURaM simulations of the coupling between the solar convection zone, photosphere, chromosphere and corona. These simulations reveal the generation of finely-structured chromospheric features. The features involve magnetic fields, and their dynamics is driven by swirls, reconnection, and flux
emergence at various scales. In this poster we investigate the complex processes that occur in the chromosphere and below and how they result in the dynamical features we see.
