Hazy weather research in China in the last decade:A review
Systematic research on haze in China has been on-going for a decade.The rapid economic expansion and urbanization has led to worsening particulate matter(PM) pollution and more frequent poor visibility events.A rapid increase in the number of hazy days has been seen over eastern China.The culprit of hazy weather is fine PM pollution.Hazy weather is often associated with photochemical pollution and composition of aerosols responsible for haze is rather complicated.In recent years,hazy weather,due to its significant environmental impacts and climatic effects,has become a hot topic,attracting wide attention from scientific community,government departments and the public.This paper surveys the literature in Chinese in the recent decade to provide a review on the process of understanding haze and research progress in hazy weather.Future research directions are also discussed.
