Multiscale Numerics for the Atmosphere and Ocean

We will propose a multi-scale model of fluid dynamics which is loosely based on LF Richardsons turbulence rhyme.

Big whirls have little whirls . . . and little whirls have lesser whirls . . .

The model will propose answers to the questions, How do larger whirls affect the circulations of smaller whirls? How do the smaller scales participate in the interactions among the larger scales.

The two key ideas are: (1) A WKB -like Fourier series decomposition of fluid velocity (2) Convection of microstructure
