This book was released on 2010 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have conducted climate analyses of natural lightning activity at Kennedy Space Center and Cape Canaveral Air Force Station (KSC/CCAFS). These analyses were conducted to improve forecasts of lightning related hazards for, and the planning of, space vehicle launches at KSC/CCAFS. If a space vehicle is hit by lightning during launch, the vehicle and payload may sustain irreparable damage. Lightning-based rules for conducting launch and vehicle preparation activities have been developed by launch managers at KSC/CCAFS. In this research, we investigated one aspect of these--the natural lightning launch commit criteria. Our goal was to improve the scientific basis for skillful forecasting of the probability of lightning hazards. Such forecasts have the potential to reduce lightning related risks to personnel and equipment, and to save millions of dollars in preparation and launch costs. Using cloud-to-ground lightning strike data from the National Lightning Detection Network during January 1989 through December 2008, we identified events in which the KSC/CCAFS natural lightning criteria for launches were violated--that is, when excessive lightning activity prevented or would have prevented launches from occurring. Based on these events, we developed daily and multi-day probabilities of lightning violations. We also developed and applied an objective statistical method for determining the seasonality of lightning and for identifying six lightning violation seasons through the course of the calendar year. These seasons were used as the basis for characterizing the temporal and spatial patterns associated with climate scale variations in lightning at KSC/CCAFS. We used atmospheric reanalysis data to analyze the physical processes that lead to interannual variability in: (a) lightning violations in each season; and (b) the start and end dates of the main lightning season. These analyses led to the identification of regional and global scale processes that tend to alter the probability of lightning violations, including: (1) shifts in the strength, latitude, and zonal extent of the Bermuda High; (2) alterations of regional scale divergence and convection, and (3) teleconnections to global scale climate variations. Several of these processes tend to be important in all or most of the six lightning violation seasons. The results of this study help form the foundation for improvements in the analysis and forecasting of natural lightning violations, and in the planning of launches at KSC/CCAFS.

Book excerpt: The Kennedy Space Center/Cape Canaveral Air Force Station (KSC/CCAFS) area borders the area of highest frequency of thunderstorms in the United States (Fig. 11). Since the majority of the thunderstorms occur in the summer months, lightning frequencies in the area during these months approach the highest level of any location in the world. This high level of frequency presents three major problems: danger to personnel damage to equipment and property and loss of time in order to minimize the previous items. Two major lightning detection systems currently in use in the KBC/CCAFS area are the Launch Pad Lightning Warning System (LPLWS) and the Lightning Location and Protection (LLP) system. Lightning activity in the KSC/CCAFS area is both a curse and a blessing. The high lightning frequency is a threat to life and slows space vehicle operations. Yet, the presence of numerous lightning strikes as well as sophisticated lightning detection systems make KSC an ideal location for lightning research to perfect lightning detection and protection.

This book was released on 2000-03 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this research effort is directed toward identifying new methods of forecasting the cessation of lightning along the Central Atlantic Coast of Florida. Cloud-to-ground lightning flashes place Air Force (AF) personnel and assets at risk almost daily at this location. Providing a more accurate method of forecasting the cessation of lightning would allow for safer and more efficient execution of AF operations. A data set consisting of 40 thunderstorm cases was identified within a 90 nautical miles (nmi) region surrounding the Melbourne, Florida WSR-88D (KMLB) site. Each case falls between the months of May and September and the years of 1995 through 1997. Simple and multiple linear regression models are built using this dataset. Variables included max Vertically Integrated Liquid water (VIL), max reflectivity, max peak current, peak cumulative flash rate, peak negative flash rate, and peak positive flash rate. Results indicate that three of the simple linear regression models to some extent accurately represent the data. Additionally, when the data set is separated by thunderstorm cell type (multi or single) and cell specific regressions are built, results indicate that the regressions based on the single-cell data set produce a substantial increase in forecast skill compared to that of climatology. In fact, some regressions are shown to improve forecast accuracy by 90% over that of climatology. Moreover, multiple linear regression models are shown to produce similar results and further reinforce the notion that each thunderstorm cell type (multi or single) behaves substantially different from the other with respect to forecasting the cessation of lightning.
