WebGranule (solar physics) A granule is a convection cell in the Sun 's photosphere. They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation . The rising part of the ... WebThe granulation is basically a convective phenomenon, each granule and its surrounding dark material representing a single convection cell. A useful feature of this volume is an extended discussion of the theory of convection, emphasizing astrophysical convection but including where relevant the theory and results of laboratory experiments.
