Weather Forecasting for Aeronautics provides forecasters and pilots wanting to study more about the art and science of predicting weather with the essential aids and methods for making practical application of their knowledge of the fundamentals of the science of meteorology. The publication first underscores the forecast problem, construction of the prognostic pressure chart, and prediction of cyclogenesis. Discussions focus on forecasting information concerning new cyclogenesis, making operational and planning forecasts, cyclogenesis off the east coast of Asia, application of weather forecasts to operational problems, and cyclogenesis in the eastern United States. The text then ponders on forecasting the movement, deepening, and filling of cyclones and movement of anticyclones in North America. The manuscript takes a look at the movement of cold lows at the 500-millibar level and their influence on surface lows, displacement of surface cold fronts, and warm frontal analysis and movement. Topics include movement of warm fronts, identification and location of warm fronts, East Coast wedge type, and warm frontogenesis. The text then examines the movement of tropical cyclones, prediction of very low ceiling and fogs, and prediction of severe weather. The publication is a dependable reference for weather forecasters and pilots.

Uncertainty is a fundamental characteristic of weather, seasonal climate, and hydrological prediction, and no forecast is complete without a description of its uncertainty. Effective communication of uncertainty helps people better understand the likelihood of a particular event and improves their ability to make decisions based on the forecast. Nonetheless, for decades, users of these forecasts have been conditioned to receive incomplete information about uncertainty. They have become used to single-valued (deterministic) forecasts (e.g., "the high temperature will be 70 degrees Farenheit 9 days from now") and applied their own experience in determining how much confidence to place in the forecast. Most forecast products from the public and private sectors, including those from the National Oceanographic and Atmospheric Administration's National Weather Service, continue this deterministic legacy. Fortunately, the National Weather Service and others in the prediction community have recognized the need to view uncertainty as a fundamental part of forecasts. By partnering with other segments of the community to understand user needs, generate relevant and rich informational products, and utilize effective communication vehicles, the National Weather Service can take a leading role in the transition to widespread, effective incorporation of uncertainty information into predictions. "Completing the Forecast" makes recommendations to the National Weather Service and the broader prediction community on how to make this transition.

First published in 1919 as part of the Cambridge Nature Study Series, this book introduces some of the basic concepts of meteorology.
