This book was released on 1979 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsynoptic convective areas are isloated, monitored and forecast through extrapolation and advection using McIDAS, (Man-Computer Interactive Data Access System), and interactive computer video-display system. Research on isolating the convective areas focuses on development of statistics using digital visual and IR GOES satellite data to delineate areal coverage and intensity. McIDAS algorithms have been developed to: (1) compute the brightness centroid; (2) form a best-fit ellipse to the region; and (3) compute areal average IR and normalized-visual brightness. Sequences of brightness centers and geometric outlines serve as input extrapolation routines to project system movement and change in area coverage and intensity. Research also has been initiated on using vertically-integrated wind fields to advect meteorological fields and disturbances. Preliminary results using these techniques for short-range forecast are presented.

Book excerpt: Work under this contract involving weather inference from GOES data and weather prediction is summarized. The research involved extrapolation and advection of meteorological events, a statistical study relating GOES data to surface thunderstorm observations, and investigating satellite indicators of short-term changes in surface visibility.

Book Synopsis The Use of Interactive Graphics Processing in Short-range Terminal Weather Forecasting by : Donald A. Chisholm
Download or read book The Use of Interactive Graphics Processing in Short-range Terminal Weather Forecasting written by Donald A. Chisholm and published by . This book was released on 1983 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The products judged most useful in preparing short-range terminal forecasts included (1) a station model time series display, (2) conventional geographic data displays presented simultaneously as four quadrant panels guidance on one screen, (3) mesoscale surface objective analyses, and (4) a forecast guidance prodecure based on 2-D upper-air trajectories and sensible weather algorithms based on imagery from the GOES satellite. The importance of half-hourly visible and IR imagery from the GOES satellite in short-range terminal forecasting was confirmed in this experiment. The participating forecasters relied more heavily on it to prepare their forecasts than any other source. The manipulation of digital imagery in a computer-based interactive graphic system through time-series looping, color enhancements, and overlaying conventional plots and analyses on it, provides a wealth of qualitative and quantitative guidance for forecasting. The numerical forecasts yielded superior rms errors compared to persistence at all forecast intervals except 1 h. At 4 h, the improvement over persistence ranged from about 21 percent for wind forecasts to about 34 percent for total cloud amount, while the 6-h quantitative precipitation forecasts yielded a 39 percent improvement.
