Abstract: Daily average and instantaneous maximum wind data from the national basic station and 8 coastal dense automatic stations in Jinzhou from September 2014 to August 2015 were used to analyze the differential characteristics of wind in Jinzhou station and coastal area. It was shown that in coastal area, the frequency of wind stronger than or equal to level 6 was significantly more than Jinzhou station, occurring more than a half, while the instantaneous maximum wind was similar to Jinzhou station. In addition, the differential daily maximum wind speed between Jinzhou station and coastal area was larger, which was 2.2 m/s on average, while the daily maximum wind speed difference was smaller at 1.1 m/s, and the difference between them increases with the increase of wind speed grade. When there were southwest and northeast wind in Jinzhou, the average difference between the average maximum wind speed and the instantaneous maximum wind speed was about 4 m/s and 2 m/s, respectively, while in case of the southeast wind and the northwest wind, the differences were smaller, both less than 2 m/s.
