| 摘 要： | 利用新一代空气质量模式系统Models-3,通过改变模式中长白山山脉区域地形高度,对比分析长白山高压以及辽宁中部城市群5城市气象环境要素的变化情况。结果表明,改变地形后,原来较强的长白山高压有了明显的减弱,城市群5城市的水平气流辐合场消失,风速增大,逆温强度也减弱,有利于污染物的传输扩散;模拟结果也表明污染物浓度有明显的降低,试验较好地揭示了长白山高压对辽宁中部城市群大气污染的影响机制。

| Abstract: | Changbai mountain anticyclone and environment factors of multi-cities in central Liaoning are analyzed by changing the simulated terrain height in the area of Changbai mountain,using the new generation air quality model system Models-3.The results show that the relatively strong Changbai mountain anticyclone has obviously weakened,level airflow convergence disappearing,wind speed becoming bigger and intensity of inversion decreasing in multi-cities of central Lioaning after the terrain height is changed,which are advantageous to the transport and diffusion of pollutants.The simulated results also indicate that the pollutant concentration has obviously reduced,and so the experiment better reveals the influence of mechanism of Changbai mountain anticyclone on atmospheric pollution of multi-cities in central Liaoning. |
