Engineering 2017, Volume 3, Issue 2,   Pages 266-271 doi: 10.1016/J.ENG.2017.01.009

Abstract:

This paper presents a concise summary of recent studies on the long-term variations of haze in NorthChina and on the environmental and dynamic conditions for severe persistent haze events.Results indicate that haze days have an obviously rising trend over the past 50 years in North China.The occurrence frequency of persistent haze events has a similar rising trend due to the continuous riselower troposphere, providing sufficient moisture for the formation of haze.
