feedback mechanisms A sequence of interactions in which the final interaction influences the original one. Also see positive feedback and negative feedback.
Climate-Feedback Mechanisms - Because the atmosphere is a complex interactive physical system, several different possible outcomes may result when one of the system's elements is altered.
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.
Leave feedback in the weather forum on your favourite instrument. Together, we can determine the best types of rain gauges to buy based on user opinions and comments.

CONVECTIVE FEEDBACK- Convective feedback deals with how a forecast model handles the vertical profile of changes in temperature and moisture that are produced from convection.
More complex feedbacks involve the possibility of changing circulation patterns in the ocean or atmosphere.
general circulation modelsA numerical representation of the climate system based on the physical, chemical, and biological properties of its components, their interactions, and feedback processes.
Three feedback mechanisms which affect global temperature change include cloud height and amount, snow and ice distribution, and atmospheric water vapor levels.
If you have any comments, suggestions or criticism please feel free to communicate them to us via the feedback link found in the footer of each page.
CISK is a positive feedback mechanism, meaning that once a process starts, it causes events which enhance the original process, and the whole cycle repeats itself over and over. Below is a video explanation of CISK.
Thanks to everyone who has contributed to our glossary, especially All Weather Inc and the AMS Glossary of Meteorology. We always welcome feedback, corrections, and suggestions. Please let us know how we can improve! ...
The net result of four primary factors including the greenhouse effect, changes in incoming solar radiation, altered patterns of ocean circulations, and changes in continental position, topography and/or vegetation. Three feedback mechanisms which ...
The program will study radiative forcing and feedbacks, particularly the role of clouds. The general program goal is to improve the performance of climate models, particularly general circulation models of the atmosphere.
instrument for measuring the wind speed by determining the force (usually by measurement of mechanical deflection) on a suspended plate exposed to the airstream. In sensitive devices for rapid response turbulence measurements, a feedback system may ...
Send me weather questions, your observations on special weather events or just how you feel about the weather and weather watching. I especially hope to see feedback from teachers on the relevance of materials to their classes or areas they would ...
