Ion-aerosol-cloud processes in the lower atmosphere

摘要: [1] Natural terrestrial radioactivity and cosmic ray ionization lead to the formation of air ions charged aerosol particles even away from regions active charge separation, such as in thunderstorms. The natural electrified state atmosphere has been studied for over a century; however, effect on physical properties aerosols clouds rarely its own right except Here we review status our understanding atmospheric their influence cloud microphysical processes. We also mechanisms that have recently proposed connect variations rate with global cloudiness weather systems. conclude mechanism linking cannot be excluded there are established electrical effects microphysics. Necessary further work includes measurements cloud, droplet, charging ion-aerosol conversion, together modeling aspects nonthunderstorm
