The stepped leader forms the first phase of the first stroke in any lightning flash. It is basically a stepwise elongating discharge in air, which carries significant charge. The charge distribution on the leader and its velocity of descent determine the attractive radius in shielding efficiency calculations. Also, the conductivity and the charge distribution on the leader tip region govern the...
متن کاملHigh‐speed video observations of a lightning stepped leader
[1] High‐speed video images of eight branches of a lightning stepped leader recorded at a frame rate of 300 kiloframes per second (kfps) (3.33 ms exposure) are analyzed, representing the fastest published frame rate measurements of stepped leader stepping by about 1 order of magnitude and the first observations of space stems/leaders associated with stepped leaders. Sixteen occurrences of space...
متن کاملVisual Simulation of Lightning Taking into Account Cloud Growth
Simulation of weather scenery in computer graphics (CG) is an important issue that has a wide range of applications related to image content, such as in movies and in various landscape simulations. In general, research to date into CG lightning has focused on generating a lightning pattern by applying probability and statistics techniques, which do not consider the generating mechanism of light...
متن کاملDielectric breakdown model in homogenous media using adaptable computational mesh
We present our latest model of lightning process. The model has two main advantages: computations were made using adaptable (e.g. non-fixed) computational mesh and we allowed branching of the stepped leader. The electrodes and the stepped leader were modelled as conductors surrounded by a homogenous dielectric media. We took in account observations of stepped leader in atmosphere and used a qua...
