| Abstract | ABSTRACT: Until recently, most of the knowledge available on the characteristics of lightning M components was obtained either from direct channel-base current measurements in triggered lightning (e.g., Thottappillil et al., 1995) or stand-alone electric-field measurements in natural lightning (e.g., Thottappillil et al., 1990). Campos et al. (2007, 2009) used stand-alone high-speed video data recorded at 1000 frames per second in order to obtain time- and occurrence-related parameters of natural lightning M components of both polarities. This type of data is very relevant for both engineering applications (such as EMC studies) and scientific research (especially sprite initiation). In the present work we combine high-speed video recordings (obtained by two different cameras, Red Lake Motion Scope 8000S and Photron Fastcam 512 PCI, operating at frame rates ranging from 1000 or 8000 frames per second) with slow and fast electric field measurements (obtained through the use of capacitive antennas) to improve the physical characterization of this phenomenon. Through the use of an algorithm developed by the authors we were able to plot luminosity-versus-time curves of each continuing current recorded by the cameras. Once an individual M component is identified in this luminosity data, it is possible to find the electric field change it has produced and that could be measured by the antennas. By using a simple electrostatic model it is possible to estimate the peak current and total charge transfer to ground of each M component observed from the slow electric field data. These intensity-related parameters can be also be correlated to occurrence- and time-related parameters such as duration, elapsed time since the return stroke and time interval between successive M components, making it possible to see at which periods of a continuing current M components can be more or less intense. |
