Yellow sand events (Kosa in Japanese) at Nagasaki (33°N, 130°E) in Japan in two spring seasons in 1999-2000 were studied on the bases of the measurements of the aerosol optical particle counter (OPC) and the sky radiometer (SR) both at the Nagasaki University. All of the yellow sand events in these springs which observed at the Nagasaki Marine Observatory of Japan Meteorological Agency are listed in Table 1,in which both the times of yellow sand event and the lowest visibility are shown in the fourth column. The results obtained by OPC measurements are shown from Figs. 1 to 16,partially acompanied with the simulutaneous SR measurements, because the SR was in trouble twice. The most severe dust episode in these two years at Nagasaki occured on 22 April 2000,however, which showed the level of one half of the greatest dust storm on 18 April 1998.
