“…The electric potential gradient was measured by a field mill and the charges were measured by a charge collector. These sensors for the balloon observation were developed first by Magono et al (1984) and they were improved on their electric circuits and features to fit our observations. Figure 2 shows an illustration of the apparatus and the electric circuit of the charge collector.…”

To investigate the mirror image relation between the electric potential gradient and charges on precipitation particles above the ground surface, a simultaneous observation system of the vertical structure of the electric potential gradient in the lower atmospheric layer and the charge on precipitation particles falling through the layer during a snowfall was developed. This system consists of a tethered balloon, observation stages on the tether and a microcomputer on the ground. Each stage has a field mill and a charge collector and it is possible to measure simultaneously the vertical component of the atmospheric electrical potential gradient and the maximum charge on precipitation particles of at most 4 stages at 5-second intervals at every 50 or 100m in altitude. Data are converted to digital signals at the stage, transmitted by digital optical communications with optical plastic fiber cables and stored in microcomputer on the ground. Several measurements were carried out in March 1985 and some results were obtained. The mirror image relation was observed on the ground but it was not so clear aloft. It was considered that the charges on the precipitation particles were reelectrified during their falling near the ground surface.

Abstract. The total charge density and the precipitation charge density inferred from six balloon soundings of electric field and precipitation charge are compared in order to examine the distribution of cloud charge density in small New Mexican mountain thunderstorms. Cloud charge density magnitudes were •ypically less than 2.0 nC m -3, and the maximum cloud charge densities were -2.1 and +6.7 nC m-. The cloud charge density made a significant contribution to the total charge density in most of the thunderstorm depth, especially in the upper positive and upper negative charge regions, where all the charge was typically on cloud particles. The largest positive cloud charge densities were found just above the main negative charge region. In the lower part of the main negative charge region, the cloud charge density was the major contributor to the total charge density, and the precipitation charge played a minor role. The cloud charge density was often zero in lower positive charge regions but was 20-50% of the total charge density in two cases. Between the upper positive charge region and the bottom of the main negative charge region the cloud charge density changes polarity and tends to become increasingly negative with decreasing altitude.
