| Resumo | Measurements of stratospheric conductivity and of electric fields associated with sferics, were obtained during two balloon flights carrying double-probe electric field detectors launched from Cachoeira Paulista, Brazil (geographic coordinates 22§44', 44§56'W) on 26 January 1994 and 23 March 1995. From data obtained in 1994, a linear relationship between the vertical quasi-DC electric field peak amplitude and the decay time constant of sferics was found for negative flashes. The results are compared to similar data for intracloud flashes. The data were supported by radar and METEOSAT satellite images. For the first time, positive and negative conductivity vertical profiles were obtained in Brazil. During the flight, at an average altitude of 27.5 kin, the balloon passed over two thunderclouds as identified, by on-board video images and photographs. The simultaneous conductivity measurements and thundercloud on-board observations allowed to determine that the presence of clouds affects the stratospheric negative conductivity, producing a extended and cumulative drop after the balloon passed over each cloud. Based on data obtained in 1995 and on the present knowledge about the differences between positive cloud to ground and intracloud flashes, two methods to distinguish between them in balloon electric field data are presented: the first is based on an estimation of the charge destroyed in the event; the second is based on the ratio between the vertical quasi-DC and the VLF electric field. The behavior of the vertical quasi-DC electric field before and after large cloud-to-ground lightning flashes is discussed and attributed to the existence a shielding layer around the thunderstorm caused by a factor decrease of three or more in the conductivity inside the cloud. |
