Fractal characteristics of simulated and LMA-detected lightning flashes
In this study, the fully 3D, bi-directional lightning model of Mansell et al. (2002) has been used to simulate lightning flashes within modeled storms with realistic charge distributions at resolutions as fine as 25m. The fractal characteristics of these flashes have been analyzed by calculating two different measures of fractal dimension: The correlation dimension and the box-counting dimension. In addition, the fractal characteristics of lightning flashes detected in 3D by the Oklahoma Lightning Mapping Array (OK-LMA) have also been analyzed using the aforementioned measures.
Comparisons between the simulated and observed flashes will be presented and implications for tuning parameters in the lightning model will be considered.
