Short summary

Severe haze days in eastern China (HD_EC) are affected by the atmospheric circulation variations on a synoptic scale, while the dominant atmospheric circulation patterns influencing HD_EC and the differences between them are still unclear. This study obtains three dominant circulation types that could lead to severe HD_EC and investigates the differences between them. The results provide a basis for establishing applicable haze prediction and management policies.
