| Abstract: | Based on the dust-storm, gale days and precipitation data at 12 meteorological stations in Chifeng, Inner Mongolia from 1961 to 2000, the geographical distribution characteristics and seasonal, annual and decadal characteristics of dust-storm are analyzed. The results show that dust-storm days in Chifeng decreased for the last 40 years, the special landscape and strong windy characteristics in this area are the main causes. The main synoptic type of dust-storm occurring in Chifeng is given too. |
