This book was released on 2018-07-17 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method is introduced for inferring the charges deposited in a lightning flash. Lightning-caused field changes (delta E's) are described by a more general volume charge distribution than is defined on a large cartesian grid system centered above the measuring networks. It is shown that a linear system of equations can be used to relate delta E's at the ground to the values of charge on this grid. It is possible to apply more general physical constraints to the charge solutions, and it is possible to access the information content of the delta E data. Computer-simulated delta E inversions show that the location and symmetry of the charge retrievals are usually consistent with the known test sources.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The 45th Weather Squadron (45WS) provides weather support to America's space program at Florida's Cape Canaveral Air Force Station (CCAFS), Kennedy Space Center (KSC), and Patrick Air Force Base (PAFB). Since CCAFS/KSC lies within Florida's "Lightning Alley", summer thunderstorms and associated hazards are a special concern for space launches and all other outdoor activities at CCAFS/KSC. Therefore, the 45WS has developed the Lightning Launch Commit Criteria (LLCC) to help minimize hazards from lightning (both naturally occurring and triggered) and vehicle electrification during the ascent phase of launch. This study has documented the spatial distributions and time evolution of total lightning and radar reflectivity in and around thunderstorms, attached anvil clouds, and detached anvil clouds near CCAFS/KSC on 30 active lightning days between 2008-11. Our goal was to determine if some of the current LLCC thresholds are too restrictive and represent missed launch opportunities, or not restrictive enough and represent a safety risk. CG flashes originating inside the convective core or its anvil can strike the ground away from the cloud edge. Since these side flashes often strike the ground under clear skies, they commonly are referred to as "bolts from the blue". Our results indicate that the vast majority of CG flashes (~94%) strike the ground = 5 n mi from cloud edge (0 dBZ) whereas 73% of CG flashes are = 3 n mi outside 0 dBZ. Three positive bolts from the blue were documented, and all came from the same storm on 29 May 2009. One of the positive flashes propagated 8.91 n mi from cloud edge. Anvil initiated lightning can distribute charge after detachment, but only for a short period. We analyzed 100 anvils within 100 km of KSC; 895 IC flashes in the anvil were initiated in the core of the storms. The first core initiated flash of each anvil typically propagated = 10 n mi. Cellular thunderstorms produce the greatest percentage of total lightning (~84%) in our dataset, but average flash distances from the core are greatest in attached anvils (~4.98 n mi). To our knowledge this is the first study to quantify the distances that lightning can extend beyond the edge of clouds. We believe the results of this research should be considered before making additional changes to the LLCC.
Download or read book Predicting Warm Season Nocturnal Cloud to Ground Lightning Near Cape Canaveral Florida written by Christopher E. Cantrell and published by . This book was released on 1999-08-01 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two aspects of nocturnal convection over Florida are examined in this study: A climatology of all warm season nocturnal cloud-to-ground lightning (COL) flashes over east central Florida, and nocturnal COL that develops near Cape Canaveral, Florida during undisturbed conditions. Seven years of warm season (May - October) radiosonde data (1992 - 1998) are used to categorize nights into one of five wind regimes based on the 1000-700 mb mean vector wind. Cloud-to-ground flashes are used to examine the spatial distribution of nocturnal lightning. Flashes are found to occur on 525 of the 825 nights with available soundings. Spatial maps of CGL flashes reveal that most occur over the Gulf Stream. Nights with flow parallel to the peninsula from the south are found to have the greatest percent occurrence of nights with COL flashes. Enhanced midlevel moisture (700 - 500 mb) increases the percent occurrence of nights having COL flashes. Midlevel lapse rates (850 - 500 mb) show little variation among the wind regimes. Streamline analyses reveal that the synoptic flow is crucial in determining thermodynamic characteristics of air over the study area. Data from the local lightning detection network reveal 74 nights during the warm season months of 1995 - 1997 with cloud-to-ground lightning within a 40 km radius of study. Surface analyses are used to eliminate nights with disturbed flow, while radar data are analyzed to eliminate pre-existing convection. A data set of nights without COL (NCOL nights) also is constructed. Stability, temperature, wind, and moisture parameters of the two categories are examined statistically. The 1000 - 800 mb lapse rate is the only temperature related parameter that statistically discriminates between the two categories. Relative humidities at 850, 800, and 750 mb all show statistically significant discrimination between categories. The K-Index is found to have the greatest forecast skill of all the standard stability parameters.

Due to its complex nature, research continues in many countries and reveals amazing results. Lightning is actively observed because of its relevance to Earth climate and air composition in addition to the classical aspects of related human fatalities and damage to forests, buildings, power lines, aircraft, structures and electronic devices. In this volume, the most important contemporary questions on lightning are addressed and analyzed under many experimental and theoretical aspects. Lightning detection techniques using ground-based and space-borne methods are described, along with network engineering and statistical analysis. Contributions detail research on atmospheric electricity, cloud physics, lightning physics, modeling of electrical storms and middle atmospheric events.
