Formation of coronal large-amplitude waves

An in-depth analysis of numerical simulations is performed to obtain a deeper insight into the nature of various phenomena occurring in the solar atmosphere as a consequence of the eruption of unstable coronal structures. Simulations take into account only the most basic characteristics of a flux-rope eruption and reveals important information on various eruption-related effects. It is shown that the eruption can cause an observable Moreton wave and a secondary coronal front only if it is powerful enough and is preferably characterized by significant lateral expansion.
