Description
In this paper we mainly aim at the understanding of temporal evolution and spatial characterization of solar granular and supergranular features. For this purpose we apply an automatic feature-tracking algorithm to three different solar granulation timeseries and to a supergranular timeseries of near-surface divergence fields. The single lifetimes are calculated measuring the time elapsing between the birth and death of each target. In addition, we investigate spatial order of surface flows studying the g2(r) function of time-averaged supergranular fields.
