摘要
为了解长江三角洲地区能见度区域状况,选取嘉兴市作为代表站点进行气象和大气污染物的同步监测分析能见度的,特征和影响因素。结果表明:晴天时能见度随相对湿度和PM2.5的变化而变化的规律很明显,雨天时能见度变化复杂。能见度与污染因子的相关性受气象因子影响很大,当控制风速时,就会减小污染因子对能见度的贡献,气象因子和能见度的相关性很复杂,不同因子作用下,气象因子对能见度的贡献不同。
For knowing the visibility factors of Yangtse delta.Selected Jinxing as observation station.its observation data was analyzed. Gained trends of the atmospheric visibility variation and its effect factor. The results showed that visibility variation is along with variation of relative humid and PM2.5 in the sunshine. Visibility variation is very complexly in a rainy day. The correlations of visibility with pollution factors were ef- fected by meteorological factor observably.when controlling wind. The correlations of visibility with pollution factors were more obvious.and that The correlations of visibility with meteorological factor were complicated, contributiveness of different factors were different with visibility.
