We observed anthropogenic aerosols and dust particles (Kosa) successively from 7 to 9 November 2005 at Cape Hedo, Okinawa with high time resolution apparatuses. An aerosol mass spectrometer with the time resolution of 10 min showed that peaks due to anthropogenic aerosol appeared at 0:00 and 15:00 on November 7. The first peak was not associated with Kosa though the cold front passed. The second one was observed at the observation point just before Kosa arrived, which was measured by Lidar system with 15 min resolution. Kosa event continued after the anthropogenic aerosols decreased. The EC/OC ratio was constant at 0.2 during the whole event. This indicates that the anthropogenic aerosol continued to be transported even when Kosa dominated.<BR> The transport pattern of both anthropogenic aerosol and Kosa was as follows. The anthropogenic aerosol originated from Taiwan and southern China was transported associating with the cold front. Then, under the high pressure system moving toward east, both anthropogenic aerosol and Kosa were transported together from China. In this case, the anthropogenic aerosol arrived slightly earlier. Kosa was continuously transported under the second high pressure system. As a result, Kosa dominated the later period of this event.
