摘要
本研究于2018年第22号台风"山竹"期间运用连续在线观测的方法,获得了广州市区PM_(10)、PM_(2.5)和PM_1质量浓度数据,分析了台风对颗粒物质量浓度的影响,不同粒径颗粒物在台风期间消除率不同,PM_(10)为56.0%,PM_(2.5)为71.4%,PM_1为74.7%,揭示了超强台风对大气颗粒物中细粒子的清除作用强于粗粒子。
In this study, the continuous online observation method was used during No.22 typhoon "Mangkhut" in 2018. The mass concentration data of PM10,PM2.5 and PM1 in Guangzhou were obtained. The influence of typhoon on the mass concentration of particulate matter was analyzed. During the typhoon, the elimination rate was different, PM10 was 56.0 %, PM2.5 was 71.4 %, and PM1 was 74.7 %, which revealed that the super typhoon had stronger elimination effect on fine particles than coarse particles.
