The propagating characteristics of low-frequency oscillation (LFO) over Eurasian mid-high latitude in boreal winter and its interannual link with the Eurasian background atmospheric circulation are analyzed by using the National Centers for Environment Prediction-National Center for Atmospheric Research (NCEP-NCAR) reanalysis data. The results show 10-30 days dominant periods of low-frequency circulation and clear southeast propagation. The meridional and zonal mean speeds of the 10-30-day LFO are about 3.4 latitudes/d and 15 longitudes/d, respectively. Further analysis shows that the interannual variation of the LFO is closely related to the Eurasian teleconnection pattern (EU). We define the negative (positive) phase of EU as conditions occurring when the ridge over the Ural area and the troughs over East Asia and northwestern European are weaker (stronger) than that in an average year such that the EU index is less than (greater than) zero. When the EU at the middle and upper troposphere is in a negative phase, the Siberian high at the low troposphere is weaker. These factors lead to weaker large-scale meridional circulation and dominant zonal circulation over the Eurasian region, which is not conducive to the propagation of the LFO over the Eurasian mid-high latitude or vice versa.
