Microdischarges observable at 30 and 50 Mcy/sec appear from within cumulus clouds in an early stage of their development whether the temperatures within the clouds are above or below 0°C. Laboratory observations of radio emission from colliding drops may provide information on the physics of clouds in the atmospheres of this and other planets.
