# Buoyancy flux

From Glossary of Meteorology

## buoyancy flux

The vertical kinematic flux of virtual potential temperature , which when multiplied by the buoyancy parameter (

*g*/*T*_{v}) yields a flux that is proportional to buoyancy, that is,This is also a term in the turbulence kinetic energy budget, describing buoyant production or consumption of turbulence. It also appears in the numerator of the flux Richardson number.
