Hourly wind fields were obtained in the period of 2016 to 2017, using the diagnostic model CALMET over the Baoding-Xiong’an area, Hebei province. Data from 22 meteorological observatories and the NCEP-fnl dataset were used in the procedure, and daily trajectories were derived. According to characteristics of the wind fields and trajectories, local air flows were classified into three types: systematic flow, local circulation, and weak synoptic winds. The analysis results depict that the proportion of the three type of flows are approximately 10%, 50% and 40%. The frequency of systematic flow is quite low, with a little more occurrence in spring and summer than that in autumn and winter. The local circulation appears more in autumn and winter than that in spring and summer. The frequency of weak synoptic winds changes little over the whole year, but slightly lower in autumn and winter. The air flow is characterized by the mountains in the northwest of the region, mountain and plain breeze circulations influence the range of about 100 km in front of the mountain, covering Baoding city and a major part of Xiong’an area. The transfer of mountain and plain breeze causes light winds in this area timely. The major transport pathways in this region are southwesterly and northeasterly, corresponding to large-scale background flows. Lateral transports caused by mountain and plain breeze circulations are relatively short in northwest and southeast directions. Occasionally, under conditions of systematic flow and weak synoptic winds in winter and spring, transport trajectories can also extend to southeast.
