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.
1. Feedback Mechanisms. Any change in the environment leading to additional and enhanced changes in that system is the result of a positive feedback mechanism. Alternatively, if a change in the environment leads to a compensating process that mitigates the change it is a negative feedback mechanism.In climate change discussions the focus is on the atmospheric radiation field as a forcing of the climate system (radiative forcing).lternatively, if a change in the environment leads to a compensating process that mitigates the change it is a negative feedback mechanism. In climate change discussions the focus is on the atmospheric radiation field as a forcing of the climate system (radiative forcing).
