Short summary
This paper demonstrates the increasing frequency of persistent haze events (PHE) in Beijing based on updated observations and explores the associated changes in large-scale atmospheric circulations with possible links to the large-scale warming trend. We propose a more concrete observation-based mechanism for explaining how the local PHE in Beijing change with large-scale climate warming via the sea surface temperature anomaly in the northwestern Pacific.
