Feedback is a word to describe a situation
in which a part of the output of a process is added to the input and subsequently
alters the output. In this way feedback can influence how the process operates.
Feedback in climate systems can take two forms :
- Positive feedback in which the feedback reinforces the original
input resulting in amplification of the output of the process. This
means that small changes in the input to the system will be cause the
system to produce larger and larger changes, resulting in instability.
- Negative feedback in which the feedback counteracts the original
input resulting in reduction of the output of the process. This means
that small changes in the input to the system will be cause the system
to produce smaller and smaller changes, resulting in the output to the
system becoming stabilised.
