Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
Feedback is also a synonym for: 1  Feedback signal - the measurement of the actual level of the parameter of interest. 2  Feedback mechanism - the action or means used to subsequently modify the gap. 3  Feedback loop - the complete causal path that leads from the initial detection of the gap to the subsequent modification of the gap.
