Based on duststorm observations during 1954-2000 from around 700 meteorological stations, this paper analyzed seasonal and inter-annual variation features. The impacts of strong wind and precipitation on the duststorms were especially emphasized. The results show that the frequency of China's duststorms is influenced by many climate factors. In NW China and northern Inner Mongolia, the main duststorm regions, the influences of climate conditions are most obvious. Wind speed and humidity are the most important controls for the seasonal cycle of duststorm frequency, and precipitation is one of the most dominant factors impacting inter-annual variability. The good correlation between the summer rainfall and duststorm frequency of next spring suggests some climate predictability.
