Flux aggregation

From Glossary of Meteorology

flux aggregation

The process by which an effective horizontal average or aggregate of turbulent fluxes is formed over inhomogeneous surfaces.

The aggregated flux differs from the spatial average of equilibrium fluxes in an area, due to nonlinear advective enhancement associated with local advection across surface transitions. Aggregated fluxes can be related to vertical profiles only above the blending height.
