Analysis of thepotential impact of the Taihu Lake on summer ozone of the surrounding cities
Based on the O 3 data of the Taihu Lake city, combined with the NCEP global reanalysis data and the HYSPLIT4 model, the influence of different types of air mass sources on the O3 concentration was analyzed by the air mass trajectory source of the Taihu Lake city from May to September 2016. Meanwhile, the distribution characteristics of the potential pollution sources of ozone in these cities are analyzed with the contribution function of potential pollution sources. The results show that O3 from the Taihu lake has great influence on that pollution in surrounding cities. The west bank of Taihu Lake has the greatest impact on Yixing, Changzhou and Wuxi, followed by Huzhou and Jiaxing, with the least impact in Suzhou.
