Short summary

This study classified the winter cold surge in eastern China into blocking cold surge and wave-train cold surge and investigated the difference of haze dispersion ability between the two types. The results show that the haze dispersion of blocking cold surge is weaker than that of wave-train cold surge. In the past 4 decades, the frequency of wave-train (blocking) cold surge shows a downward (upward) trend, which means that the ability of cold surge to disperse haze is declining.
