| Feedback mechanisms | Aerospace | A sequence of inter-actions in which the final interaction influences the original one. Source: EPO. Negative Feedback. An interaction that reduces or dampens the response of the system in which it is incorporate Positive Feedback. An interaction that increases or amplifies the response of the system in which it is incorporated. . (references) | |
| Feedback mechanisms | Science | Factors which increase or amplify (positive feedback) or decrease (negative feedback) the rate of a process. An example of positive climatic feedback is the ice-albedo feedback. (references) | |
| Feedback mechanisms | Weather | 1: A sequence of interactions in which the final interaction influences the original one. Also see positive feedback and negative feedback. (references) | |
| 2: A mechanism that connects one aspect of a system to another. The connection can be either amplifying (positive feedback) or moderating (negative feedback). See climate feedback. (references) | |||
| Limatic feedback mechanisms | Geophysics | A feedback is an enhancement (positive feedback) or a damping (negative feedback) of an initial change, in this case in the climate system. For example, when less energy reaches the earth, temperature decreases and the area covered by snow increases. The albedo of the planet decreases, reflecting more energy towards the atmosphere. Consequently less energy is available at the surface, and temperature further decreases. The whole "cycle" from the initial cooling to the further cooling is a feedback. It is a positive feedback in this example. (references) | |
