| Abstract: |
We examine the role of small-scale granulation in helping to drive supergranulation and even larger scales of convection. The granulation
is modeled as localized cooling events introduced at the upper boundary of a 3-D simulation of compressible convection in a rotating
spherical shell segment. With a sufficient number of stochastic cooling events compared to uniform cooling, we find that supergranular
scales are realized, along with a differential rotation that becomes increasingly solar-like. |
