Short summary

We found that an atmospheric transmission constituted by a western-type positive North Atlantic Oscillation (NAO+) pattern and a positive East Atlantic/West Russia (EA/WR+) pattern plays an essential role in the persistent haze events in Beijing. As the origin of the atmospheric transmission, the state of the western-type NAO pattern can help to increase the predictability of winter haze days and persistent haze events in Beijing on interannual and daily-to-weekly timescales.
