Wisconsin's Weather and Climate


Book Description

The land that is now called Wisconsin has a place in weather history. Its climate has ranged from tropical to polar over hundreds of millions of years--and even today, that's the seeming difference between July and January here. And Wisconsinites have played key roles in advancing the science of meterology and climatology: Increase Lapham helped found the National Weather Service in the nineteenth century; Eric Miller was the first to broadcast regular weather reports on the radio in the 1920s; Verner Suomi pioneered tracking weather by satellite; and Reid Bryson has been a leader in studying global climate change. Wisconsin's Weather and Climate is written for weather buffs, teachers, students, outdoor enthusiasts, and those working in fields, lakes, and forests for whom the weather is a daily force to be reckoned with. It examines the physical features of Wisconsin that shape the state's climate--topography, mid-latitude location, and proximity to Lakes Superior and Michigan--and meteorological phenomena that affect climate, such as atmospheric circulation and air mass frequency. Authors Joseph M. Moran and Edward J. Hopkins trace the evolution of methods of weather observation and forecasting that are so important for agriculture and Great Lakes commerce, and they explain how Wisconsin scientists use weather balloons, radar, and satellites to improve forecasting and track climate changes. They take readers through the seasonal changes in weather in Wisconsin and give an overview of what past climate changes might tell us about the future. Appendices provide climatic data for Wisconsin, including extremes of temperature, snowfall, and precipitation at selected stations in the state. The authors also list sources for further information. Vignettes throughout the book provide fascinating weather lore: o Why there are cacti in Wisconsin o The famous Green Bay Packers-Dallas Cowboys "Ice Bowl" game of 1967 o The Army Signal Corps' ban on the word tornado o Advances in snow-making technology o The decline of the Great Lakes ice industry

Reginald Sutcliffe and the Invention of Modern Weather Systems Science


Book Description

Despite being perhaps the foremost British meteorologist of the twentieth century, Reginald Sutcliffe has been understudied and underappreciated. His impact continues to this day every time you check the weather forecast. Reginald Sutcliffe and the Invention of Modern Weather Systems Science not only details Sutcliffe’s life and ideas, but it also illuminates the impact of social movements and the larger forces that propelled him on his consequential trajectory. Less than a century ago, a forecast of the weather tomorrow was considered a practical impossibility. This book makes the case that three important advances guided the development of modern dynamic meteorology, which led directly to the astounding progress in weather forecasting—and that Sutcliffe was the pioneer in all three of these foundational developments: the application of the quasi-geostrophic simplification to the equations governing atmospheric behavior, adoption of pressure as the vertical coordinate in analysis, and development of a diagnostic equation for vertical air motions. Shining a light on Sutcliffe’s life and work will, hopefully, inspire a renewed appreciation for the human dimension in scientific progress and the rich legacy bequeathed to societies wise enough to fully embrace investments in education and basic research. As climate change continues to grow more dire, modern extensions of Sutcliffe’s innovations increasingly offer some of the best tools we have for peering into the long-term future of our environment.
