A MODEL OF SOLAR GRANULATION THROUGH INVERSE CASCADE

Non-linear interactions between small fluid elements in an energetically open system facilitate the formation of large coherent stable structures. This is known as self-organization. We interpret solar granulation on all scales to be the result of self-organization processes occurring in the turbulent medium of the solar atmosphere. This mechanism provides explanations for the intrinsic weakness of mesogranulation and the rare appearance of giant cells in addition to the sizes and lifetimes of these structures. The entire energy spectrum from the smallest granules to the largest giant cells brings out the prevalence of Kolmogorov's K-5/3 law.
