Johannesburg' air quality is significantly influenced by winter wood and coal burning in surrounding townships and the East Rand industrial corridor, producing some of southern Africa's worst seasonal pollution episodes. Summer thunderstorms provide effective air washing, while the highveld altitude of 1,750 metres aids background dispersion on most days.
