Field experiments of an electrostatic fog-liquefier

Abstract Fog particles charged by corona discharge are attracted toward the inversely polarized electrode and instantaneously liquefied. Outdoor experiments have been successfully performed with the newly proposed electrostatic fog-liquefier.

Laser radar observation of the fog caused by “yamase wind” from the Okhotsk sea

A Mie scattering laser radar with a powerful flashlamp-pumped dye laser has been developed to measure “Yamase” fog which is caused by very cold air intrusion as a result of Okhotsk high pressure. The inner structure of the “Yamase” fog—height profile, horizontal distribution, speed, thickness of the fog layer and its time development, periodic movement and dominant periods were observed and analyzed for the first time by laser radar of our institute.

Development of an Electrostatic Fogliquefier and Its Field Experiments

A new fogliquefier has been developed and demonstrated in a laboratory and an outdoor field. Fog charged by corona discharge is attracted toward the inversely polarized electrode and instantaneously liquefild. Outdoor experiments were successfully performed at a rice field with a newly invented electrostatic fogliquefier.
