12. Analyzing 60,000 Supergranules to Determine their Subsurface Flow Profile

Contributed by Tom Duvall. Posted on April 29, 2014

Analysis of a large number of supergranules observed with HMI and simulations with a convectively stabilized solar model imply that the average supergranular cell has a peak upflow of 240 m s-1 at a depth of 2.3 Mm and a corresponding peak outward horizontal flow of 700 m s-1 at a depth of 1.6 Mm.
