Based on the daily NCEP/NCAR reanalysis data during 1959-2014, the climatic mean characteristic of Siberian storm track was firstly investigated. And then, the energy diagnostic equation was used to discuss its possible maintenance mechanism in winter and compared with Siberian storm track with the North Pacific Storm Track (NPST) and Northern Atlantic Storm Track (NAST). Results show that:(1) Siberian storm track exists independently in four seasons. Although its intensity is the weakest and its position is to the north compared with the NPST and NAST, it still can be defined as a weak storm track. (2) The seasonal variation of Siberian storm track intensity is similar to that of the NPST. Unlike the northeastern location of the jet of two oceanic storm tracks, the Siberian storm track is located on the west side of the East Asian Polar-front Jet. (3) The further energy analysis results show that the baroclinic energy conversion (K_e4) is the main energy source of the Siberian storm track. The advective transport term of time-averaged airflow to eddy kinetic energy (K_e1) and eddy ageostrophic geopotential flux (K_e3) also play an important roles in the maintenance of the storm track in its eastern part.
