Abstract: Based on the wind speed record from 2005 to 2020 provided by the meteorological station at the 100-kilometer gale area,wind speed metrics were obstained by caculating 2-minute average wind speed,gale days,daily maximum wind speed,and daily extreme wind speed after a solid quality control.The results show that:（1）With the increase of time resolution,the difference between wind speed metrics generated by the 24-and the 4-observations was noticeably enlarged,and the deviation increases with the increase of wind level.（2）The variation of wind speed was closely related to the atmospheric circulation in the region,which was strengthened by the topographic feature of the surrounding landscape.Under the synergism influence of solar radiation and topography,the annual average wind speed is 8.3 m·s-1,the annual average gale days were 200.6 d,and the surface wind speed maintained a high-level.（3）The average wind speed reached its peak in spring and summer,with long-lasting high-level wind speed.（4）The period that had the maximum average wind speed appeared around 04:00,CST.The period that occupied the highest wind speed at the same day concentrated between 17:00-20:00,CST.The two periods did not completely coincide with each other.
