摘要: In the spring of 1991, individual aerosol particles were collected on electron microscopic grids in Beijing (China) and Nagasaki (Japan). order to study change chemical composition Asian dust-storm during transport, dust examined using an microscope equipped with energy-dispersive X-ray (EDX) analyzer. An isentropic backward-trajectory analysis was carried out obtain transport path particles. Spatial distributions clouds by Geostationary Meteorological Satellite (GMS) also used examine presence along path. mixed internally sea salt (mixed particles) ranged from 16 100 % among air over Nagasaki. For two cases that same events observed Nagasaki, containing present abundantly a case would have been influenced largely maritime atmosphere transport. It is suggested these formed cloud processes.
