Available in PDF, EPUB and Kindle. Book excerpt: Trajectory forecasting techniques have been introduced at 75 Air Weather Service forecast units. Trajectory data, in the form of parcel origins and forecast temperatures, dew points, and cloud amounts, are transmitted twice daily to these forecast units. These data are a by-product of the Air Force Global Weather Central's (AFGWC) Multi-Level Cloud-Forecasting Model and are used to supplement conventional forecast tools. In addition, 600-meter (above ground level) temperature and dew-point forecasts from AFGWC's Boundary-Layer Model are included in the trajectory bulletin. Trajectory techniques have been integrated subjectively and objectively into forecast procedures with encouraging results. Ceiling and visibility forecasts prepared with trajectory data have verified better than forecasts prepared without trajectory data. This report discusses past evaluation programs, characteristics of the trajectory model, and procedures for using the data in forecast applications. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Winter Trajectory Test Program was conducted as part of the AWS Forecaster Assistance Program. The objective of this test was to determine if three-dimensional trajectories derived from the output of the AFGWC Six-Level Forecast Model are useful in the preparation of terminal forecasts. Hq AWS personnel used trajectory data to evaluate forecasts prepared at detachments in the central and eastern United States and to modify some of these forecasts. These trajectory data improveed the four-month verification of the terminal forecasts by 3.1 percent. Tests were conducted in 1 Wea Wg and 2 Wea Wg and results from these overseas units are discussed. Forecast procedures and the application of objective rules developed during the winter evaluation are described in several case studies. (Author).
