Proposal Summary:
We propose to explore the relative influences of differential solar heating, radiative transfer, and thermal convection on the dynamics of the atmosphere and interior of Jupiter. Numerical simulations of heat and angular momentum transport will be performed by solving the 3-D anelastic equations of motion in a spherical shell. The effects of thermal convection, radiative transfer, and transport by baroclinic eddies in radiatively stabilized portions of the atmosphere and interior will be rigorously calculated. Our simulations will be the first to couple radiative transfer calculations with solution of the anelastic equations for thermal convection. The calculations will be performed on a high-speed massively parallel supercomputer capable of meeting the computational demands imposed by the high spatial and temporal resolution required to model the flow. By resolving eddy motions occurring in radiatively stabilized layers in addition to convective motions driven by internal heating, and by including radiative transfer, our model will provide an important new potential to attack fundamental questions about jovian atmospheric dynamics that to date have not been satisfactorily addressed.
