Abstract. Sandy dust weather occur frequently in arid and semi-arid areas. It is important to actually detect the sandy dust grain concentration or the visibility of the sandy dust weather for weather forecasting. In this paper, based on numerical calculation of the effective detection distance of different radar detecting the sandy-dust weather with different strength, a scheme to detect sand/dust weather applying existed meteorological radar stations is proposed in this paper. The scheme can be efficient to detect sandy dust weather, for it makes a good supplement to the current deficiencies in detecting sandy dust weather and it’s a cost-saving detection way by using the existed meteorological radars. In addition, the effect of charges carried by sand/dust grains and the relative humidity on the effective detection distance of radar is also investigated, and it shows that these effects will not change the proposed scheme. It will be promising to detect the sandy dust weather in the way of disastrous weather precaution by using this scheme.

Short summary
Sandy dust weather are common disastrous weather in many parts of the world. Dust storms have been shown to have deleterious impacts to human health. In this paper, based on numerical calculation of the effective detection distance of different radars detecting the sandy-dust weather with different strengths, a scheme to detect sandy dust weather applying existed meteorological radar stations is proposed in this paper.
