The impact of early winter (December) North Atlantic Oscillation (NAO) on the subsequent dramatic seesaw haze intensity alternation (DSHA) phenomenon in the North China Plain (NCP) between late winter months of January and February is identified based on observational analyses and Community Earth System Model Large Ensemble Numerical Simulation (CESM-LENS) datasets in this study. Our research suggests that the late winter abrupt subseasonal haze intensity enhancement is preceded by the negative NAO-like pattern in December, and vice versa. Detailed analysis indicates that persistent North Atlantic tripole (NAT) sea surface temperature (SST) patterns play a crucial oceanic bridging role in relaying the delayed influence of NAO from December to the following January. In this circumstance, negative December NAO can induce a profound planetary-scale zonal Rossby wavetrain emanating from the central North Atlantic, in which the southern branch of this wavetrain propagates the negative NAO signal downstream to northeastern Asia, forming the Northeast Asian cyclonic anomaly in January and facilitating the repressed haze intensity via inducing the haze-unfavorable meteorology. However, in the subsequent February, the cyclonic anomaly centered southeast of the Yamal Peninsula plays a critical role in prolonging the influence of the December NAO, acting as an intermediate atmospheric bridge effect. The notable Northeast Asian anticyclonic anomaly can be induced in February accordingly, thus facilitating the haze intensity enhancement in the NCP via inducing the haze-favorable meteorology. As such, the dramatic subseasonal haze enhancement in the NCP between late winter months can be triggered by the preceding early winter NAO. It shows that the early winter NAO could be considered as a crucial precursory atmospheric signal predicting the late winter DSHA phenomenon in the NCP.
