Скачать книгу - The Tropics and the Traveling Gaze

Dig into the science of ancient times and unearth amazing discoveries! * Have you ever wondered where paper comes from, who made the first known maps, or how the ancient Egyptians were able to build the pyramids? * Would you like to make your own sundial, discover how to detect earthquakes, or learn to write in hieroglyphics? * Are you looking for great ideas for your next science fair project? If you answered «Yes» to any of these questions, then Ancient Science is for you! From Greek lighthouses and Roman bridges to Chinese kites and Mesopotamian soap, you'll investigate some of the greatest scientific discoveries and the people who introduced them to the world. Dozens of fun-packed activities help you see for yourself how the earliest humans cultivated plants, why instruments make different sounds, how fireworks get their explosive power, and much more. All of the projects are safe and easy to do, and all you need is everyday stuff from around the house. So step back in time and take an amazing journey with Ancient Science!

The global climate changes that led to the expansion and contraction of high latitude ice sheets during the Quaternary period were associated with equally dramatic changes in tropical environments. These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have acted as drivers of global climate change over a range of timescales. The aim of Quaternary Environmental Change in the Tropics is to provide a synthesis of the changes that occurred in tropical terrestrial and marine systems during the Pleistocene and Holocene, complementing data-derived reconstructions with output from state-of-the-art climate models. It is targeted at final-year undergraduate students and research specialists, but will provide an introduction to tropical Quaternary research for a variety of other readers.

What do we mean by the tropics? The weather and the climates it produces across the tropical zone are significantly different from those experienced by the people living in higher latitudes, so forecasters across Europe and much of North America are unfamiliar with its effects. In this book, Jim Galvin demystifies the topic in this zone that is increasingly of interest to those studying weather and climate. This book was written for weather forecasters, meteorology, environmental science and geography students as an introductory guide. It builds on the experience of the author, his professional experience in the World Area Forecast Centre at the Met Office, Exeter, using studies into the weather and climate seen within the tropical air mass conducted over many years. Its unique approach presents a practical approach to tropical weather studies, drawing on both academic and practical knowledge, covering air mass dynamics, seasonal changes, moist and dry weather, climate variability and human health in chapters and appendices that build up the overall picture, summarising our current state of knowledge. As an overview, it covers the broad range of effects connected with climate and weather in a straightforward way and is clearly illustrated throughout.
