Document Summary
Lecture 11 - changing winds: global climatic change. A description of typical weather conditions for a location and time of year. Based on statistics accumulated over a long period of time (at least 30 years) Transport of warm or cold, moist or dry air. Geography e. g. rain shadows from mountains, land/ sea breezes. A change in a will cause a change in b , which in turn will cause a change in a in the same direction is called a positive feedback. However, if a change in a cause a change in b and that will cause in a in the opposite direction then it is a negative feedback. Changes in albedo will change the local climate. Large-scale albedo changes can affect the global climate. Feedback: climatic change can cause changes in cloud and snow cover, which in turn cause further climatic change. Dust and sulphuric acid particles launched into the stratosphere.
