(1) The long range trend of the number of days of yellow sand dust events observed at Nagasaki Marine Observatory were compiled for the 88 years from 1914 to 2001. This statistical analysis suggests the frequent occurrence of duststorm in latest Several years.(2) The measurements of atmospheric aerosols by an optical particle counter for two years showed that a great deal of large particles was significant at the dust events, but sometimes the density of smaller particles was also on higher level, which would suggest the atmospheric pollutants from the Asian continent.(3) A sky radiometer newly innovated in this research project and a dual wavelength laser radar system, which came from National Institute of Environmental Studies, was also utilized for sounding the vertical profiles of the mineral dust particles. Their synthetic observational data showed very interesting feature, and then we are now going to analyze the structure and movement of dust particles for constructing the substantial image of the yellow sand dust event.

(1) 编制了长崎海洋观测站从 1914 年到 2001 年 88 年的黄沙尘暴天数长期趋势，统计分析表明近几年沙尘暴频繁发生。(2) 两年来光学粒子计数器对大气气溶胶的测量显示，沙尘暴发时大颗粒物较多，但有时较小颗粒物的密度也较高。 （3）本研究项目中新发明的天空辐射计和来自国立环境研究所的双波长激光雷达系统也用于探测矿物尘埃颗粒的垂直剖面。他们的综合观测数据显示出非常有趣的特征，接下来我们将分析尘埃颗粒的结构和运动，以构建黄沙尘埃事件的实质图像。
