近十年中国灰霾天气研究综述

Hazy weather research in China in the last decade:A review

中国系统的进行灰霾天气研究已经10周年了.由于经济规模迅速扩大和城市化进程加快,大气气溶胶污染日趋严重,由气溶胶污染造成的能见度恶化事件越来越多,我国东部地区灰霾天气迅速增加.灰霾天气的本质是与光化学污染相关联细粒子气溶胶污染,形成灰霾天气的气溶胶组成非常复杂.近年来由于灰霾天气日趋严重引发的环境效应问题,和气溶胶辐射强迫引发的气候效应问题,广泛地引起科学界、政府部门和社会公众的关注,而成为热门话题.本文主要依据中文文献讨论了中国近10年来对灰霾天气的认识过程,灰霾天气的研究进展,以及今后灰霾天气研究的重点方向.

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.
