| 摘 要： | 通过中尺度气象模式和高分辨化学模式的耦合,研究广州地区O3的时空分布及其变化特征.结果表明,近地层上O3的分布与地面源排放的分布有非常好的对应关系,并且呈现出多中心分布;O3浓度随时间变化有很好的日变化周期,模拟结果与实测对比有较好的一致性;对单站O3浓度随高度的变化趋势的分析表明,对流层低层O3的日变化幅度较大.

| Abstract: | By coupling meso-scale meteorological model and high-resolution chemicasl model, we studied the characteristics of spatial and temporal distribution and variation of ozone in Guangzhou.The results showed that the distribution of O\-3 in the lower layer of troposphere has a good relation with that of the surface emission and indicated the multi-center distribution.Local O 3 concentration has a good diurnal cycle.It gave a good agreement between the simulated results and monitoring results.The analysis of vertical O\-3 concentration profile of mono-station showed that O\-3 concentration has higher range of diurnal change in lower layer of troposphere. |
