摘　　要：基于2014年9月至2015年8月锦州国家基本观测站及沿海8个锦州沿海加密自动站逐日及逐小时10 min平均最大风向、风速和极大风向、风速观测数据,统计分析了锦州站及沿海海域风的差异特点。结果表明,沿海大于等于6级以上的风明显多于锦州站,全年6级大风日数在半数以上,而极大风与锦州站差异不大;从沿海海域日最大风风速、日极大风风速与锦州站日最大风风速、日极大风速差值来看,日最大风风速差值较大,平均差为2.2 m/s;日极大风速差值较小,为1.1 m/s,且两者都存在随着风速等级的增大差值增大。其中,锦州风向为西南风和东北风时,日最大风风速和日极大风平均差值较大,分别为4 m/s和2 m/s左右,东南风和西北风差值较小,小于2 m/s。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.
