Flux aggregation

From Glossary of Meteorology



flux aggregation[edit | edit source]

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.


  1. The process of combining different surface characteristics from neighboring heterogeneous regions into an average value for the area.
