Lightning in Wildfire Smoke Plumes Observed in Colorado during Summer 2012
Pyrocumulus clouds above three Colorado wildfires (Hewlett Gulch, High Park, and Waldo Canyon; all during the summer of 2012) electrified and produced localized intracloud discharges whenever the smoke plumes grew above 10km MSL (approximately 2458C). Vertical development occurred during periods of rapid wildfire growth, as indicated by the shortwave infrared channel on a geostationary satellit...
متن کاملAn evaluation of the performance characteristics of the U.S. National Lightning Detection Network in Florida using rocket-triggered lightning
[1] The performance characteristics of the U.S. National Lightning Detection Network (NLDN) were evaluated using rocket-triggered lightning data, acquired in the summers of 2001–2003 at the International Center for Lightning Research and Testing (ICLRT), at Camp Blanding, Florida. During the 3-year period, 37 flashes, containing a total of 159 (158 negative and 1 positive) strokes, were trigger...
متن کاملPerformance Analysis of the North American Lightning Detection Network Using Cn Tower Lightning Data
The North American Lightning Detection Network (NALDN) is a commercial lightning detection network composed of the U.S. National Lightning Detection Network (NLDN) and the Canadian Lightning Detection Network (CLDN). The NALDN was developed to provide lightning information by accurately detecting and locating most cloud-to-ground (CG) lightning strokes and a small fraction of discharges produce...
متن کاملLocation Accuracy Improvements using Propagation Corrections: A Case Study of the U.S. National Lightning Detection Network
A number of applications that employ information from Lightning Locating Systems (LLSs) require accurate estimates of the ground-strike location of return strokes in Cloud-to-Ground (CG) flashes. A study by Schulz and Diendorfer (2000) has shown that the primary factors limiting accurate geo-location of these strokes are (1) the delay of arrival-time of the return-stroke radiation field produce...
متن کاملCloud-to-ground Lightning Warnings Using Electric Field Mill and Lightning Observations
1. Introduction Automated lightning warning systems are a critical component of many day-today operations. This is particularly true of airports but also applies in some industrial applications, such as mining and the manufacture, testing, and handling of explosives and weapons. Many automated lightning warning systems use a combination of lightning detection information and one or more electri...
