During the course of this century, meteorology has become unified, physics-based, and highly computational. Calculating the Weather: Meteorology in the 20th Century explains this transformation by examining thevarious roles of computation throughout the history of meteorology, giving most attention to the period from World War I to the 1960s. The electronic digital computer, a product of World War II, led to great advances in empirical, theoretical, and practical meteorology. At the same time, the use of the computer led to the discovery of so-called"chaotic systems,"and to the recognition that there may well be fundamental limits to predicting the weather.One of the very few books covering 20th century meteorology, this text is an excellent supplement to any course in general meteorology, forecasting, or history of science.
