The temporal and spatial distribution characteristics of dusty weather in China in spring 2004 are analyzed on the basis of the data from surface synoptic maps (8 times per day) and T213 model products. The results show that there were 15 major dusty weather processes, more in March and less in April and May, and most of them were weak. Further research shows that because the temperature was higher and the precipitation was less than the normal value in the earlier months, the soil moisture was less and the soil surface was drier in spring in the northern China. When the cold air attacked North China frequently in March, more dusty days and severe dust storms occurred. After March, the dusty weather events decreased quickly because of less cold air activities and weaker dynamic condition.
