Correlating Total Lighting to High Impact Storms: An Analysis of Earth Networks Dangerous Thunderstorm Alerts (DTAs) Performance over CONUS for 2013
The detection of total lightning data, especially IC lightning, enables improvements in the lead time of severe weather prediction and alerting. Using total lightning data from the ENTLN, a real-time lightning cell tracking program has been developed to identify and track the properties of storm cells, such as the lightning flash rate, directional movement and speed of the lightning/storm cells. The Earth Networks Dangerous Thunderstorm Alert (DTA) has been developed based on this lightning cell tracker and is currently being used in a nowcast system.
This presentation is a continuation of previous studies from 2011 and 2012. The methodologies employed in creating the Dangerous Thunderstorm Alerts and the statistical analysis on the performance of the DTAs will be discussed along with updated analysis of correlation with other aspects of lightning. The objective of this study is to provide validation of the effectiveness of the DTA, by comparing DTAs with storm reports over CONUS for the year of 2013.
