Abstract: | I suggest that the exploding granule phenomenon is a consequence of the observed internal granular motions and the conservation of angular momentum. When a granule rising from the convection zone penetrates into the overlying stable region it is stretched out horizontally. Conservation of angular momentum in the internal motions changes its form into a vortex ring. A time sequence of photographs showing an exploding solar granule is described. The proposed mechanism is illustrated by a laboratory simulation and a numerical calculation. |
