Tainan's air quality reflects the Taiwan southern coastal plain's flat position on the Taiwan Strait, with vehicle traffic on surrounding expressways and the petrochemical, semiconductor, and manufacturing corridor contributing elevated industrial PM2.5. Consistent Taiwan Strait and South China Sea breezes provide maritime ventilation, while transboundary Chinese Pearl River Delta industrial pollution on northwesterly winds contributes regional background and Tainan generally maintains moderate to elevated Taiwan southern industrial metropolitan readings throughout most of the year.
