Climatology of lightning activity in Australia: spatial and seasonal variability

A climatology of lightning ground flash density is examined for the Australian region based on 18 years of data. The dataset and methodology used are consistent with that of a previous study based on eight years of data. Lightning flash densities are obtained from two satellite instruments—the Lightning Imaging Sensor and the Optical Transient Detector. A climatological map of lightning ground ...

Urban lightning climatology and GIS : An analytical framework from the case study of Atlanta , Georgia

There are three underdeveloped components of urban cloud-to-ground lightning studies: (1) the integration of multiple flash descriptors into more informative summary metrics of flash production, (2) the comparison of flash patterns by thunderstorm type, and (3) the correspondence of urban flashes with underlying land use. We used a GIS to integrate these components as part of an analysis of war...

Cloud-to-Ground Lightning Downwind of the 2002 Hayman Forest Fire in Colorado

The Hayman forest fire occurred near Denver, burning ~138,000 acres during 8 June-2 July 2002. It produced aerosol that filled the troposphere over Colorado, allowing an investigation of the effects of increased aerosol concentration on cloud-to-ground (CG) lightning polarity. Specifically, we examine whether positive CG (+CG) flashes are favored in smoky environments. Aerosol optical depth (AO...
