Document Summary
The exam will include some definitions of key terms (2-3 sentences) and short answer discussions of important ideas. You may be asked to make sketches to illustrate your answers. Although i will not expect you to memorize equations, you should be familiar with the terms (variables) in equations that we"ve talked about in class, and know what the equations are used for. The following list covers most of the topics that i consider important from the first few weeks of class: Definition of steady state: the energy in and out are equal. Difference between positive and negative feedbacks, examples of each. Forcing and response in earth"s climate system, phase lags. ~positive feedback: a response that enhances the forcing. An example is the melting of sea ice, which makes temperatures warmer because there is less albedo to reflect energy back to space. ~negative feedback: diminishes disturbances to a system to restore steady state. They act the opposite of a certain change.
