【摘要】 大气颗粒物对人群健康有着重要影响,是城市空气质量的重要指标。通过上海、杭州、南京、苏州空气污染指数(API)的对比,分析长三角各城市空气质量状况与其地理位置和季节主导风向的关系。并利用HYSPLIT4轨迹模式,模拟计算了几次污染过程中的气团运动轨迹,探讨了区域大气输送对城市空气质量的影响。更多还原

【Abstract】 Atmospheric particles are of significant influence on people’s health, and it is an important index of urban air quality. By the comparison of API of Shanghai, Hangzhou, Nanjing and Suzhou, the relationship between the urban air quality in Yangzi Delta and location as well as the prevailing wind direction was analyzed. Then the air mass trajectories during several pollution episodes were simulated by trajectory model HYSPLIT4, and the impacts of regional air mass transportation on the air quality of these cities.更多还原
