中文摘要: 应用三维风场,借助计算气块路径的方法,对一次沙暴天气引起的浮尘飘移,进行了逆向追踪计算,得出了浮尘源地的位置和浮尘飘移的三维空间路径。经与天气实况对比,两者基本相符。这对于预测大气中污染物的飘移和确定污染源的位置,具有实际意义。
Abstract:With the three-dimensional wind fields and calculation on the path of an air parcel,the floating-dust shift caused by a sandstorm was tracked in opposite direction. The position of the floating-dust source and its three-dimensional path are determined. The result is consistent with the weather reports. It could be applied practically in determining the source of pollutants in the atmosphere.
