Abstract: The electrical charge transferred to highly insulated spheres by the diffusion of ions from ionized moving air is directly measured. The equilibrium charge is proportional to the logarithm of the ratio of the positive and ...

Abstract: Measurements in a giant expansion chamber show that the size of newly formed cloud droplets depends critically upon the cleanliness of the processed air. Droplets formed in ordinary air are small, but droplets large enough ...

Abstract: Measurements have been made of the radii and free electric charges of cloud particles in supercooled cumuliform-type clouds which occurred at a 6580-ft MSL mountain observatory. Simultaneously, the positive and negative ...

Abstract: The size and the free electric charge of more than 6000 individual natural cloud droplets have been measured. The measurements were made at a mountain laboratory in southeastern United States in strato-cumulus clouds and ...

Abstract: The system of differential equations which governs the equilibrium charge distribution around a charged cloud located in an atmosphere with constant ionization is solved numerically for clouds with differing water content. ...

Abstract: Atmospheric electric measurements were made during the summer of 1958 from the summit of Mt. Washburn in Yellowstone Park, Wyoming. These measurements included the electric field, the positive and negative electrical ...
