A Study of Supergranulation through Its Parameters

Paniveni Udayashankar

Abstract

Supergranulation is examined through its various parameters such as Area, perimeter, circularity and fractal dimension. A connection amongst these parameters throws light on the turbulent aspect of this convective feature. Area and perimeter at various latitudes are also studied in detail. The spread shows an asymmetric dispersion with a minimum dimension at around ±25º because there is a theoretical calculation which indicates that the enhanced fields will reduce the supergranular cell sizes (Chandrasekhar, 1961) around these latitudes. A different technique of analysis on a larger sample could consolidate these findings.
