Download or read book Automated Cell Detection as a Mesocyclone Precursor Tool written by F. Ian Harris and published by . This book was released on 1984 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automated cell detection in radar observations of convective storm complexes has been explored as a severe storm indicator. Six-dB peaks were detected in the radar reflectivity fields and their characteristics were monitored as a function of time. It was found in a severe tornadic storm that the number of cells and the average intensity of the cells had trends that appear to be characteristic of super-cell storms with these trends being identifiable at least 45 min before the touchdown of the first tornado and 90 min before the touchdown of a maxi tornado. None of these trends could be detected in a storm system that produced only a funnel cloud. This second storm did produce a tornado vortex signature. It would appear that the peak detection algorithm has the potential of extending the warning period for severe weather associated with super-cell and for indicating the potential of extremely severe weather. Testing has been limited and therefore these results must be considered somewhat tentative.

Download or read book Short Term Forecasting of Cloud and Precipitation written by Alan R. Bohne and published by . This book was released on 1988 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A methodology for real-time operations has been developed for the short-term forecasting of cloud and precipitation fields. Pattern recognition techniques are employed to extract useful features from the data field and extrapolation techniques are used to project these features into the future. To reduce computational load, contours defined by directional codes are used to delineate features. These contours are subdivided and attributes such as length, location, and location of each segment are determined. Segment matching is performed for successive observations and attribute changes are monitored over time. Several techniques for the forecasting of attributes have been explored, and an exponential smoothing filter and a linear trend adaptive smoothing filter have been chosen as most appropriate. Currently analysis is performed on a minicomputer and image processor system utilizing radar reflectivity data. Refinement of these techniques and extension into a more comprehensive short term forecasting program is planned.

Download or read book Mesoscale Convective Processes in the Atmosphere written by Robert J. Trapp and published by Cambridge University Press. This book was released on 2013-03-25 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new textbook seeks to promote a deep yet accessible understanding of mesoscale-convective processes in the atmosphere. Mesoscale-convective processes are commonly manifested in the form of thunderstorms, which are fast evolving, inherently hazardous, and can assume a broad range of sizes and severity. Modern explanations of the convective-storm dynamics, and of the related development of tornadoes, damaging 'straight-line' winds and heavy rainfall, are provided. Students and weather professionals will benefit especially from unique chapters devoted to observations and measurements of mesoscale phenomena, mesoscale prediction and predictability, and dynamical feedbacks between mesoscale-convective processes and larger-scale motions.
