Dustfall in China’s western loess plateau as influenced by dust storm and haze events

Over a period of 12 h, the deposition rates of airborne dust during three dust storm and haze events in March and April 1999 at Lanzhou (36°N, 104°E) decreased successively from 0.43–2.23 μg cm −2 min −1 in initial 2-h intervals to 0.05–0.08 μg cm −2 min −1 in final intervals. Simultaneously, the ma...

Description
Summary:Over a period of 12 h, the deposition rates of airborne dust during three dust storm and haze events in March and April 1999 at Lanzhou (36°N, 104°E) decreased successively from 0.43–2.23 μg cm −2 min −1 in initial 2-h intervals to 0.05–0.08 μg cm −2 min −1 in final intervals. Simultaneously, the mass median diameter of the falling dust decreased from 33.3–40.2 to 24.2–32.1 μm. The rate of dust deposition during dust storm and dust haze events was 10–25 times higher than the annual average (0.025 μg cm −2 min −1), and a single dust storm or haze event contributed about 3% to the annual dust deposition flux (1.33·10 4 μg cm −2 yr −1). However, particulate matter
