| 摘 要： | 基于青岛站1899—2015年117 a年平均风速和青岛市88个自动站1961—2015年逐日风速资料，结合NCEP/NCAR再分析资料，分析青岛风速气候变化特征。结果表明:在全球气候变化背景下，青岛站的风速变化是一个先增强（1899—1938年），再波动维持（1939—1991年），之后又减小（1992—2015年）的过程；20世纪90年代后的风速变化对1961—2015年青岛站风速明显下降（0.41 m·s-1/(10 a)）贡献显著；1961—2015年青岛偏北风减小趋势为0.33 m·s-1/(10 a)；青岛东南沿海地区平均风速减小趋势大于北部内陆地区的分布特征是对青岛城市化发展水平区域差异的响应，城市化对地面年平均风速减弱贡献率约为-17.3%。

| Abstract: | The wind speed changes in Qingdao are analyzed on the basis of annual average wind speed data from Qingdao Station from 1899 to 2015 and daily wind speed data from 88 automatic stations in Qingdao from 1961 to 2015 together with NCEP/NCAR re-analyses. The results show that in the context of global climate change, the wind speed changes at Qingdao Station were reinforced from 1899 to 1938, sustained with fluctuations from 1939 to 1991, and diminished from 1992 to 2015. The wind speed changes since 1990s did significant contribution to the wind speed downtrend at Qingdao Station from 1961 to 2015, approximately by 0.41 m·s-1 per decade. Moreover, the northerly wind decreased approximately by 0.33 m·s-1 per decade from 1961 to 2015. The wind speed downtrend in the southeastern coastal areas of Qingdao is greater than that in the northern inland areas, which responds to the regional difference of urbanization in Qingdao. The urbanization contributes to the weakened surface annual average wind speed at -17.3%. |
