抄録: Atmospheric turbid conditions caused by fine particles, which are defined as the particles in the size range between 0.3 and 1.0μμm in diameter, are occasionally significant in recent years over the Nagasaki area in Japan. These conditions make the horizontal visibility very low as 4-5 km despite of fair weather. We studied two significantly turbid cases rich with fine particles, which took place during 25-27 March 2003 and on 23 May 2005, from the viewpoint of a detailed understanding of their influences to visibility and the properties of fine aerosols. As a result of this study, the noticeably low visibility conditions due to fine particles are closely connected with the high concentration of sulfur which transported from the Asian continent. Fine particles sometimes make very turbid conditions in spring without the influence of yellow sand dust particles. This peculiarity should be paid further attention from the viewpoint of air quality conservation over East Asia.
