Abstract Analysis of meteorological data during 2000—2007 collected from 12 weather stations in the blown-sand source area threatening Beijing and Tianjin shows that the spatio-temporal distribution of sand-dust weather is determined by the combination of gale and precipitation in space and time to a great degree. The gale-precipitation combination significantly influenced the spatial sand-dust weather distribution (R2=0.960) and the monthly sand-dust weather variation (R2=0.995). The influence on the annual sand-dust weather variation was still outstanding (R2=0.864) though the effect was partly canceled by the management engineering through improving vegetation coverage in the sand source region. The significant correlations of sand-dust weather with gale days and precipitation imply that the correlation functions from multi-factor regression can be applied to forecast sand-dust days in the source area of blown-sand threatening Beijing and Tianjin.
