Identification of atmospheric transport and dispersion of Asian dust storms

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 m, 1500 m, 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, recent increase of ADS occurrence rate was statistically significant in 99.9 % confidence limit.
