This book was released on 1965 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five-day mean and daily meteorological data observed since 1949 are analyzed empirically in order to derive useful climatological and forecasting relationships between surface weather elements and the circulation pattern. The synoptic climatology of 5-day precipitation, surface temperature, 700-1000-mb. thickness, and sea level pressure is investigated by constructing fields of simple linear correlation between these elements and the simultaneous anomaly of 700-mb. height over North American and adjacent oceans. The relation of precipitation and temperature to the field of sea level pressure is studied in a similar fashion. On the basis of the analogy are drawn concerning the association between each weather element and other meteorological factors. Schematic models are then constructed showing preferred portions of the circulation pattern at 700-mb. and sea level for opposite extremes of weather in different parts of the United States.

Download or read book Statistical Postprocessing of Ensemble Forecasts written by Stéphane Vannitsem and published by Elsevier. This book was released on 2018-05-17 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical Postprocessing of Ensemble Forecasts brings together chapters contributed by international subject-matter experts describing the current state of the art in the statistical postprocessing of ensemble forecasts. The book illustrates the use of these methods in several important applications including weather, hydrological and climate forecasts, and renewable energy forecasting. After an introductory section on ensemble forecasts and prediction systems, the second section of the book is devoted to exposition of the methods available for statistical postprocessing of ensemble forecasts: univariate and multivariate ensemble postprocessing are first reviewed by Wilks (Chapters 3), then Schefzik and Möller (Chapter 4), and the more specialized perspective necessary for postprocessing forecasts for extremes is presented by Friederichs, Wahl, and Buschow (Chapter 5). The second section concludes with a discussion of forecast verification methods devised specifically for evaluation of ensemble forecasts (Chapter 6 by Thorarinsdottir and Schuhen). The third section of this book is devoted to applications of ensemble postprocessing. Practical aspects of ensemble postprocessing are first detailed in Chapter 7 (Hamill), including an extended and illustrative case study. Chapters 8 (Hemri), 9 (Pinson and Messner), and 10 (Van Schaeybroeck and Vannitsem) discuss ensemble postprocessing specifically for hydrological applications, postprocessing in support of renewable energy applications, and postprocessing of long-range forecasts from months to decades. Finally, Chapter 11 (Messner) provides a guide to the ensemble-postprocessing software available in the R programming language, which should greatly help readers implement many of the ideas presented in this book. Edited by three experts with strong and complementary expertise in statistical postprocessing of ensemble forecasts, this book assesses the new and rapidly developing field of ensemble forecast postprocessing as an extension of the use of statistical corrections to traditional deterministic forecasts. Statistical Postprocessing of Ensemble Forecasts is an essential resource for researchers, operational practitioners, and students in weather, seasonal, and climate forecasting, as well as users of such forecasts in fields involving renewable energy, conventional energy, hydrology, environmental engineering, and agriculture. - Consolidates, for the first time, the methodologies and applications of ensemble forecasts in one succinct place - Provides real-world examples of methods used to formulate forecasts - Presents the tools needed to make the best use of multiple model forecasts in a timely and efficient manner

Download or read book Short range Forecasting of Cloudiness and Precipitation Through Extrapolation of GOES Imagery written by H. Stuart Muench and published by . This book was released on 1981 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development and testing of an objective technique to forecast cloudiness and precipitation through extrapolation of satellite imagery. By utilizing on objectively determined cloud-motion vector, the technique makes local forecasts of satellite parameters (brightness and IR temperature), with high temporal resolution, using simple linear extrapolation. Algorithms are then used to convert the satellite parameters to total cloud cover, probability of 1-hour precipitation, and presence of low, middle, and high clouds. The test program computed motion vectors and made forecasts out to 7 hours, in half-hour steps, at 30 locations. The program was tested on 12 spring and fall cases, using half-hourly GOES imagery. For periods beyond 2 hours, forecasts of cloud cover and precipitation were markedly better than persistence, which deficiencies in specification hindered short-period performance. Forecasts of cloud layers were worse than persistence due to inadequate specification algorithms. The net results were quite encouraging, and further refinements and developments are planned.
Download or read book Composited Local Area Forecast Techniques written by H. Stuart Muench and published by . This book was released on 1988 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previously developed advection forecast technique was modified to include data extracted from satellite imagery. A forecast experiment was then conducted using a data base gathered at AFGL during March 1984. This experiment was designed to test the usefulness of : (a) 3-hour forecast updates, (b) a biquadratic interpolation, and (c) cloud and precipitation information from satellite imagery. The test results confirmed earlier tests in that advection using space-averaged 500-mb winds produced the best overall scores and that in general the scores for 1 - 15 hours were better than persistence. The age of the advection flow (3, 6 or 9 hours old) did not affect forecast score, making updates useful. The biquadratic interpolation procedure produced better fits to observation than bilinear and appears to have improved forecasts. There was but a small benefit from adding satellite information to surface observations when forecasting cloud cover and hourly precipitation. the difficulties of trying to forecast even 30 to 50 percent of the time-change variance suggest that alternative approaches such as mesoscale modeling will be needed for accurate, reliable short-range forecasts.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
