Abstract:

In recent years, there was a dust phenomenon in arid and semi – arid areas of Iran, which have less precipitation mean, that lead to great worry. Dust is one of the atmosphere phenomena that rest unsuitable environmental consequences. Drought is one of the most important phenomenons, which effect on dust rate. In this paper, we investigate drought and increasing dust days in Khuzestan state. In this order, we adopt precipitation and dust days rate in Khuzestan synoptic stations, and we apply SPi climatic index or Standard Precipitation Index to determine drought rate. This index is used to determine precipitation lack in different time periods. When the drought time increased, the number of dust says increased, too. In this project, also, we investigate geological and geomorphologic condition and water resources in this state and their role in increasing dust. Drought index SPi is accounted for all state stations and present in tables 3-12. The results showed that in all of stations, any increase in drought severity cause to increase in dust days. The only exception here is, Bandar Emam Station, and its reason refer to relatively high humidity in this place.

Keywords: Drought,Dust,SPi index.
