The Charge Separation in Natural Blowing-Snow and Blowing-Dust

[摘要] In order to find the cause of positive electric-fields measured in blowing-snow and negative fields measured in blowing-dust, a new apparatus was constructed, and some experimental analyses were carried out.From the analyses, we found an interesting regularity which controls the sign of electriccharge on particles and simultaneously generated ions: the sign of small particles suspended in the space of the apparatus and predominantly generated ions agree with that of chargecarrier of particle materials.This regularity may be supposed as one of effective integrated mechanism of many kinds of strong electric-field generation such as thunder-cloud, the volcanic eruption, the sand-storm and many other explosion phenomena which have occurred at every kind of plants using powder particles.
