Time-averages are common observables in analysis of experimental data
and numerical simulations of physical systems. We describe a
PDE-theoretical framework for studying time-averages of dynamical
systems that evolve in both fast and slow scales. Patterns arise upon
time-averaging, which in turn affects long term dynamics via nonlinear
coupling. We apply this framework to geophysical fluid dynamics in
spherical and bounded domains subject to strong Coriolis force and/or
Lorentz force.
