On the possibility of sprites in other planetary atmospheres

摘要：

Lightning have been detected in clouds on other planets either by direct imaging of the optical emissions from flashes emanating through the atmosphere or else by remote sensing of electromagnetic signals such as sferics or whistlers guided by the planets magnetosphere. We present results of theoretical calculations of the breakdown electric field in the CO2 atmosphere of Venus and the H2-He atmospheres of Jupiter and Saturn. We use several values of the lightning charge moments that can be expected in the thunderstorms occurring on the planets, and predict the expected altitudes for the occurrence of sprites in their atmospheres. Detection methodology by orbiting spacecraft is suggested.
