Detection of mesogranulation on the sun

DOI:https://doi.org/10.1086/183539· OSTI ID:6185319
Time averages of velocity measurements at disk center on the quiet Sun reveal the presence of a fairly stationary pattern of cellular flow with a spatial scale of 5--10 Mm. Such mesogranulation has a spatial rms vertical velocity amplitude of about 60 ms/sup -1/ superposed on the larger scale supergranular flows. The lifetimes of mesogranules appear to be at least 2 hr.
