Weather Matters

It is the purpose of this book to provide the meteorological knowledge and tools to improve the risk management of energy industry decisions, ranging from the long term finance and engineering planning assessments to the short term operational measures for scheduling and maintenance. Most of the chapters in this book are based on presentations given at the inaugural International Conference Energy & Meteorology (ICEM), held in the Gold Coast, Australia, 8-11 November 2011. The main aim of the conference was to strengthen the link between Energy and Meteorology, so as to make meteorological information more relevant to the planning and operations of the energy sector. The ultimate goal would be to make the best use of weather and climate data in order to achieve a more efficient use of energy sources. This book seeks to realise the same objective.

The past 15 years have seen marked progress in observing, understanding, and predicting weather. At the same time, the United States has failed to match or surpass progress in operational numerical weather prediction achieved by other nations and failed to realize its prediction potential; as a result, the nation is not mitigating weather impacts to the extent possible. This book represents a sense of the weather community as guided by the discussions of a Board on Atmospheric Sciences and Climate community workshop held in summer 2009. The book puts forth the committee's judgment on the most pressing high level, weather-focused research challenges and research to operations needs, and makes corresponding recommendations. The book addresses issues including observations, global non-hydrostatic coupled modeling, data assimilation, probabilistic forecasting, and quantitative precipitation and hydrologic forecasting. The book also identifies three important, emerging issues-predictions of very high impact weather, urban meteorology, and renewable energy development-not recognized or emphasized in previous studies. Cutting across all of these challenges is a set of socioeconomic issues, whose importance and emphasis-while increasing-has been undervalued and underemphasized in the past and warrants greater recognition and priority today.

A kaleidoscopic book that illuminates our obsession with weather--as both physical reality and evocative metaphor--focusing on the ways in which it is perceived, feared, embraced, managed, and even marketed.

From leading climate scientist Dr. Friederike Otto, this gripping book reveals the revolutionary science that definitively links extreme weather events—including deadly heat waves, forest fires, floods, and hurricanes—to climate change. “Meet the forensic scientists of climate change; if you like CSI, you’ll be equally enthralled with the skill and speed these folks exhibit. But the stakes are infinitely higher!” —Bill McKibben, author of Falter and The End of Nature Tied with Hurricane Katrina as the costliest cyclone on record, Hurricane Harvey caused catastrophic flooding and over a hundred deaths in 2017. Angry Weather tells the compelling, day-by-day story of the World Weather Attribution unit—a team of scientists that studies extreme weather events while they’re happening—and their race to track the connection between the hurricane and climate change. As the hurricane unfolds, Otto reveals how attribution science works in real time, and determines that Harvey’s terrifying floods were three times more likely to occur due to human-induced climate change. At the forefront of cutting-edge climate science, Friederike Otto uncovers how the new ability to determine climate change’s role in extreme weather events can dramatically transform how we view the climate crisis: from how it will affect those of us who are most vulnerable, to the corporations and governments that may find themselves held accountable in the courts. The research laid out in Angry Weather will have profound impacts, both today and for the future of humankind. Published in Partnership with the David Suzuki Institute.

As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.

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.
