Abstract

Influence of sand and dust weather on air pollution in Lanzhou is discussed by using the particulate matter monitoring data and the ground conventional meteorological observation data during 2001 to 2010. The results are shown as: ?Sand and dust weather in Lanzhou mainly happens in spring. It presents a 4 years periodicity between the two peaks of occurrence of sand and dust weather. The occurrence is obviously decreased after the peak. ?During sand and dust weather, air pollution index as well as PM10 concentration rises sharply. The average ratio is 1.16 between PM10 average concentration and PM10 average concentration eliminated sand and dust weather. The occurrence of the sand and dust weather has significantly heightened PM10 average concentration in the spring. The heightening effect becomes obvious with the more occurrence of the sand and dust weather. ?Variable pressure in 3 hours is positive during the sand and dust weather. The wind direction mainly locates in the range from the north to the east. Visibility is also influenced if the sand and dust weather occurs.
