How do scientists predict the weather? What tools and instruments help them make forecasts? How far in advance can they make good predictions? Weather forecasting is a tricky science. Forecasters gather current weather data and study trends and historical patterns. They use their expertise to predict what kind of weather is likely coming next—with help from computers, satellites, and other machines. In this fact-packed book, discover what it really takes to forecast Earth’s weather.
This book provides readers with a broad understanding of the fundamental principles driving atmospheric flow over complex terrain and provides historical context for recent developments and future direction for researchers and forecasters. The topics in this book are expanded from those presented at the Mountain Weather Workshop, which took place in Whistler, British Columbia, Canada, August 5-8, 2008. The inspiration for the workshop came from the American Meteorological Society (AMS) Mountain Meteorology Committee and was designed to bridge the gap between the research and forecasting communities by providing a forum for extended discussion and joint education. For academic researchers, this book provides some insight into issues important to the forecasting community. For the forecasting community, this book provides training on fundamentals of atmospheric processes over mountainous regions, which are notoriously difficult to predict. The book also helps to provide a better understanding of current research and forecast challenges, including the latest contributions and advancements to the field. The book begins with an overview of mountain weather and forecasting chal- lenges specific to complex terrain, followed by chapters that focus on diurnal mountain/valley flows that develop under calm conditions and dynamically-driven winds under strong forcing. The focus then shifts to other phenomena specific to mountain regions: Alpine foehn, boundary layer and air quality issues, orographic precipitation processes, and microphysics parameterizations. Having covered the major physical processes, the book shifts to observation and modelling techniques used in mountain regions, including model configuration and parameterizations such as turbulence, and model applications in operational forecasting. The book concludes with a discussion of the current state of research and forecasting in complex terrain, including a vision of how to bridge the gap in the future.
Kids experience what makes the weather tick in this hands-on introduction to the science of meteorology. The authors explain how to make equipment to measure rainfall, wind direction, and humidity, record measurements and observations in a weather log, make weather predictions, and perform other related activities.
This book offers a complete primer, covering the end-to-end process of forecast production, and bringing together a description of all the relevant aspects together in a single volume; with plenty of explanation of some of the more complex issues and examples of current, state-of-the-art practices. Operational Weather Forecasting covers the whole process of forecast production, from understanding the nature of the forecasting problem, gathering the observational data with which to initialise and verify forecasts, designing and building a model (or models) to advance those initial conditions forwards in time and then interpreting the model output and putting it into a form which is relevant to customers of weather forecasts. Included is the generation of forecasts on the monthly-to-seasonal timescales, often excluded in text-books despite this type of forecasting having been undertaken for several years. This is a rapidly developing field, with a lot of variations in practices between different forecasting centres. Thus the authors have tried to be as generic as possible when describing aspects of numerical model design and formulation. Despite the reliance on NWP, the human forecaster still has a big part to play in producing weather forecasts and this is described, along with the issue of forecast verification – how forecast centres measure their own performance and improve upon it. Advanced undergraduates and postgraduate students will use this book to understand how the theory comes together in the day-to-day applications of weather forecast production. In addition, professional weather forecasting practitioners, professional users of weather forecasts and trainers will all find this new member of the RMetS Advancing Weather and Climate series a valuable tool. Provides an end-to-end description of the weather forecasting process Clearly structured and pitched at an accessible level, the book discusses the practical choices that operational forecasting centres have to make in terms of what numerical models they use and when they are run. Takes a very practical approach, using real life case-studies to contextualize information Discusses the latest advances in the area, including ensemble methods, monthly to seasonal range prediction and use of ‘nowcasting’ tools such as radar and satellite imagery Full colour throughout Written by a highly respected team of authors with experience in both academia and practice. Part of the RMetS book series ‘Advancing Weather and Climate’
This is the ultimate guidebook for anyone who needs to know the details of operational weather analysis and forecasting, not just theoretical aspects and basic concepts. It is geared toward meteorology professionals, students, pilots, flight dispatchers, amateurs, storm chasers, and spotters. Basic physical concepts are reviewed, and then the book covers thermodynamics, surface analysis, and upper analysis. There is a thorough overview of weather systems, including their thermal structure, dynamics, and effects. Special problems such as thunderstorms, winter weather, and tropical weather are treated in detail. The margins are filled with forecasting facts, hard-hitting quotes, educational stories, and even a few fun weather jokes. With added emphasis on analysis, visualization, and awareness of model limitations, readers learn to use tools properly and are always a step ahead.
Have you ever listened to a weather forecast stating there may be a slight chance of showers but the rain is coming down so hard you are seriously considering a lifejacket while standing on the dock? During such times, one suggestion to the forecaster runs through everyone's mind: "Look out the window!!" That is certainly one of the most accurate methods to forecast the immediate weather. Everyone knows the look of the sky when a thunderstorm or squall is moving in, but few know how to determine what is in store more than a few hours ahead. Frank has taken the mystery out of weather forecasting in his book Marine Weather Forecasting. He explains how to tell more about the weather, for hours and days to come, than any broadcast. But you must know what to look for when you go on deck. The wind, clouds, moon and sun all tell the story and Frank explains how to read these signs. Anyone can understand Frank's detailed descriptions of forecasting and the illustrations add to the ease. Caution: After reading this book you may never rely on another broadcast report. Illustrated
How do meteorologists design forecasts for the next day's, the next week's, or the next month's weather? Are some forecasts more likely to be accurate than others, and why? Making Sense of Weather and Climate takes readers through key topics in atmospheric physics and presents a cogent view of how weather relates to climate, particularly climate-change science. It is the perfect book for amateur meteorologists and weather enthusiasts, and for anyone whose livelihood depends on navigating the weather's twists and turns. Making Sense of Weather and Climate begins by explaining the essential mechanics and characteristics of this fascinating science. The noted physics author Mark Denny also defines the crucial differences between weather and climate, and then develops from this basic knowledge a sophisticated yet clear portrait of their relation. Throughout, Denny elaborates on the role of weather forecasting in guiding politics and other aspects of human civilization. He also follows forecasting's effect on the economy. Denny's exploration of the science and history of a phenomenon we have long tried to master makes this book a unique companion for anyone who wants a complete picture of the environment's individual, societal, and planetary impact.
