| Abstract: | Taking a typical haze weather occurred in Pearl River Delta region as an example,during the same period of this haze episode,the most extensive sand and dust storm of 2010 occurred in Central Asia,Mongolia and northern China.Cold front reached Hong Kong and Guangzhou on early morning,22 March 2010,resulting opposite impact on air quality at these two cities.Rapid deterioration of air quality in Hong Kong was observed,with the aerosol concentration exceeding 700 μg/m3.However,the quality and visibility of inland part of Pearl River Delta region including Guangzhou,Foshan and Dongguan improved significantly during this period.The opposite event triggered a controversy on the nature of this process.Weather analysis,flow field analysis,remote sensing analysis as well as physical and chemical characteristics of aerosols analysis were performed to discuss the causation of this event.Results indicated that Hong Kong experienced air quality and visibility impairment due to the haze weather caused by dust while Pearl River Delta hinterland region observed end of 5 days haze weather and visibility as well as air quality improvement in virtue of cold front passing by. |
