%X A continuous strong dust weather occurred from April 6 to 8 in 2002 in most part of China,especially in middle and east Inner Mongolia,north and north-east China.This long time dust weather event was induced by Mongolian cyclone and surface cold front.The spatial and temporal distribution and development of dust concentration and structure were simulated by a coupled dust model with non-hydrostatic mesoscale model.The modeling results were validated with surface weather reports and observed dust particle concentration as well as satellite remote sensing image for dust.The results showed that the coupled dust model could depict the full processes of continuous dust weather's formation,development,movement and weakening.The model reasonably revealed the vertical structure and the spatial-temporal evolution of dust concentration during strong sand-dust weather.The dust development and its strength and range from the model were in good agreement with the real observations.High resolution dust model could be a good method for mechanism study of dust weather's occurrence,development and transport and for dust forecasting and warning in operation.
