Abstract : Directional antennas at Cape Kennedy were used to passively detect radio noise emitted by storm clouds in the 100 to 1000 MHz spectral region. With the antenna programmed to automatically raster-scan an area of the sky, a slaved display provided a picture or map of the electrical activity. A number of such pictures are shown, including a sequence indicating high-altitude electrical activity in a tornado-producing thunderstorm. (Author)
