气载污染物在大气环境中的输运取决于风场的时空特征。在事故条件下,快速、客观地建立复杂地形地区的三维风场,对于提高估算污染物浓度及预测事故后果的精度,进而制订正确的应急对策,至关重要。以质量守恒为约束条件的风场诊断模式是在此领 The transport of airborne pollutants in the atmosphere depends on the temporal and spatial characteristics of the wind field. Under the condition of accident, setting up three-dimensional wind field in complex terrain area quickly and objectively is very important for improving the accuracy of estimating pollutant concentration and forecasting the accident consequence and then formulating correct emergency measures. To the conservation of the wind as the constraint condition of the wind field diagnosis mode is here
