| 摘 要： | 根据非静力动力学气象模式和拉格朗日粒子模式建立的多尺度模式，利用欧洲预报数据ECMWF和不同分辨率的地形数据，对欧洲长距离示踪试验（ETEX）的扩散过程进行阶段性再现模拟，并将多尺度扩散模拟结果与ETEX试验监测结果进行对比分析，以考查该模式在多尺度扩散模拟中的应用。研究结果表明，多尺度扩散模拟结果与观测结果具有较高的空间分布相关性；扩散模拟结果有效地反应了当时的区域流场特征。

| Abstract: | A multi-scale model is built by means of non-hydrostatic dynamics meteorological model and Lagrange particle model. According to the model, the ECMWF forecasting data and different resolution terrain data are used for the simulation of the European Tracer Experiment (ETEX), and simulation results and the monitoring results of ETEX are analyzed to study the application of the diffusion model to multiscale simulation. The results show that the multi-scale diffusion simulation results and the observations have high spatial distribution correlations, and that the diffusion simulation results effectively reflect the characteristics of the regional flow field at that time. |
