Weather: How It Works And Why It MattersBasic Books, 7 de gen. 2008 - 240 pàgines Scientists have delved deep into the smallest particles of matter and have extended their view to the far reaches of the universe, but still seem unable to predict the temperature five days hence. In this intriguing book, two scientists examine recent progress in the fields of meteorology and climatology. Amid colorful anecdotes of the Galapagos, Siberia, and places closer to home, they describe the earth's atmosphere, its origin and structure, and the forces that have shaped and continue to affect it. They explore temperature, pressure, and other properties of air and weather, including warm and cold fronts, highs and lows, clouds, trade winds, prevailing westerlies, and sky phenomena such as rainbows, halos, coronae, and sun dogs. The authors end with a discussion of the major threats to earth's atmosphere brought on by human activity, including global warming and ozone depletion, and argue that pure science -- not politics -- should dictate our policy responses. |
