Document Summary
Chapter 9: wind: small scale and local systems. Troughs= line that is low; valley can be high or low. A front has a low and a trough. Pressure gradient force= change in pressure over distance: molecular viscosity: when the slowing of uid is due to the random motion of the gas molecules. Scales of motion: microscale: small chaotic motions within smoke that cause it to tumble and turn. Eddies with a diameter of a few meters or less. Can also sway branches, swirl dust and papers into the air. Formed by convection or by wind blowing past obstructions and are usually short, last only a few minutes: mesoscale: next largest scale; circulations range from a few kilometers to about. Last longer than microscale motions, some cases as long as a day. Includes local winds, (which form along shorelines and mountains) and thunderstorms, tornadoes, and small tropical cyclones: synoptic scale: circulations around high and low pressure areas.
