Nanjing's air quality reflects the Yangtze River valley's flat alluvial plain in Jiangsu, with vehicle traffic on surrounding expressways and the petrochemical, steel, and electronics manufacturing corridor contributing elevated industrial PM2.5. East China Sea and Yangtze delta breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Nanjing generally maintains moderate to elevated Yangtze Delta provincial capital readings throughout the year.
