Supergranulation-Scale Simulations of the Solar Convection Zone
Abstract
We report on the status of solar surface supergranulation scale simulations (48Mm x 48Mm x 20Mm (deep)). Effects of f-plane rotation at a latitude of 30 degrees are included. These simulations were bootstrapped from smaller width calculations which were relaxed for 3 turnover times (6 days) and have now relaxed for another turnover time at the full width. The size of dominant structures increases with depth, due to the halting of some downdrafts and the merging of others as they descend, to form the boundaries of the larger horizontal upflows. These large scale structures are also visible at the surface with a velocity amplitude that decreases linearly with increasing size. We thank NASA and NSF for their support of this work.
