Short summary
The number of winter haze days over the north-central North China Plain in 2014 was largest in the past 30 years. With the anticyclone circulation over North China taken as an intermediate, the positive phases of the east Atlantic/west Russia, western Pacific, and Eurasian patterns led to a larger number of haze days in 2014. The related external forcing included preceding autumn Arctic sea ice, winter and pre-autumn surface temperature, and pre-autumn sea surface temperature in the Pacific.
