small perturbation

In the context of tangent linear and adjoint models, perturbations are considered small if their development can be described with acceptable accuracy by tangent linear equations.

In many cases, this class of perturbations includes those that are comparable in magnitude to the typical analysis errors of operational forecast models.
See tangent linear approximation.
