WeatherBug® Total Lightning System WeatherBug Total Lightning Visualization (WTLV) WeatherBug Total Lightning Visualization (WTLV) is a comprehensive web-based lightning visualization and modeling tool that enables access to live lightning data for severe weather prediction and monitoring. The WTLV solution provides advanced analytics and display of lightning network data enabling visualization of: • Lightning parameters and display using the lightning data from WTLS and/or WTLN Solid line of IC and CG • Symbology and color coding for lightning types lightning within storm cell • Animation • Summary of displayed lightning • Historical data recall • Parameters displayed will include: – Time (local to the strike) – Latitude/longitude – Peak current IC and CG lightning, and – Polarity of peak current tornado warning during a severe storm event – IC/CG classification WeatherBug Total Lightning NetworkTM The WeatherBug Total Lightning Network™ (WTLN) incorporates the most advanced lightning location technology available and is the first comprehensive in-cloud (IC) lightning and cloud-to-ground (CG) detection network worldwide. With more than 320 lightning sensors deployed worldwide, WTLN is the largest total lightning detection network available today. The ability to detect IC lightning at high efficiencies is critical for the advanced prediction of severe weather phenomena such as: • Tornadoes • Downburst winds • Cloud-to-Ground lightning strikes These potentially deadly weather events often occur within 5 to 30 minutes of IC flash initiation. Through efficient detection and monitoring of total lightning, significant improvements in severe storm lead times can be gained.
