| Description: |
Backward trajectories of individual Asian dust storm (ADS) events were calculated using the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) at four representative stations in Korea. A total of 743 ADS events and associated 2229 (endings of altitudes at 1000, 1500, and 2000 m per ADS event) backward trajectories from four stations were traced from January 2003 to August 2015. Regardless of the locations of the observed stations and the threshold time divide, a recent increase in the ADS occurrence rate was statistically significant with a 99.9 % confidence limit.
