Mass-balance gradient

Alternative definitions (1), class: vernacular (0)
Term: Mass-balance gradient
Definition: The rate of change of mass balance with altitude, that is, the derivative db/dz of the mass-balance profile b (z). If mass balance varies linearly with altitude, the mass-balance gradient will be constant with z; if not, the gradient will vary with z. The mass-balance gradient at the equilibrium-line altitude is called the activity index.
