Simulation experiments of the electric structure in a thundercloud : Electric interaction between charged fog and water drops and Electric field change by double charged fog

摘要

Experiments on electric interaction between charged fog and water drops as the indoor simulation for the electric structure in a thundercloud are carried. The charged fog instead of the charged cloud is used in this experiment. The electrifications of water drops passing through the charged fog in the various situation are measured in the experiment. As a result, it is found that water drops have electric charge under various situations which depended on the separation conditions of water and ice drops at its moment. Measurements of electric field on the ground on various charged fogs are also carried out. It is found from this experiment that neutral fog coming into under the charged layer is separated electrically by electrostatic induction and the fog act like lowering the charge layer.
