Evaluation of thunderstorm indices from ECMWF analyses, lightning data and severe storm reports

Electrical thunderstorm nowcasting using lightning data mining

This paper presents a study developed at SIMEPAR (Paraná state weather service) using lightning data for electrical thunderstorm nowcasting. Thunderstorm electrical data collected at SIMEPAR such as lightning location, time of occurrence, current intensity, polarity, etc, are stored in real-time in a relational database. As a first step of this study, Microsoft Business Intelligence bundled wit...

Lightning Characteristics and Relationship to Preliminary Local Storm Reports

The Storm Prediction Center (SPC) has traditionally utilized cloud-to-ground (CG) lightning for a variety of purposes but recently intra-cloud (IC) flash data as part of total (CG + IC) lightning has been made available. To further explore characteristics of considering both CG and IC flashes in an operational setting, a systematic evaluation and comparison of the Vaiasala’s National Lightning ...

Derivation of Thunderstorm Ice Hydrometeor Characteristics from Lightning Measurements

Previous calculations (Blyth et al., 2001) predicting that the lightning frequency f is proportional to the product of the downflux p of solid precipitation (graupel) and the mass upflux I of ice crystals, have been subjected to preliminary examination by analyzing data from the STERAO experiment. The analysis has yielded provisional support for this flux hypothesis. The physical reasons for su...
