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.
Just remember that positive feedback mechanisms enhance the original stimulus and negative feedback mechanisms inhibit it. http://anatomyandphysiologyi.com/homeostasis-positivenegative-feedback-mechanisms/. Another good example of a positive feedback mechanism is blood clotting.
