中文摘要:
      在对相对湿度(RH)序列进行均一性检验和订正的基础上,分析了武汉4个城市站RH的气候学特征和长期变化趋势。结果表明:1)迁站对RH序列引起较大非均一性偏差,其中武汉站2010年迁站引起的偏差达到8%;2)城区年平均RH较高,介于75-85%之间,武汉站最高;3)每年1月至6月城区RH逐渐增加,6月达到峰值,之后缓慢减少,但季节内变化一般很小,月际间差异仅有0.1%~2.5%,存在夏季RH最高,春、秋次之,冬季最低的季节性特征;4)武汉城市区域1961-2015年平均RH总体呈长期减少趋势,线性变化趋势-0.81%/10a,20世纪90年代之后下降趋势加剧;5)近55年城区春、秋、冬三个季节平均RH均呈不同程度的下降,以春季最为明显,夏季存在较为显著的上升趋势,但1991后年及四季均呈现显著的下降趋势。
Abstract:
      Based on the homogeneity test and correction of the relative humidity series, climatic characteristics and long-term trend of Wuhan urban area were analyzed. The results showed that:1) The non-homogeneity deviation caused by relocating stations in the relative humidity series was prodigious, and the deviation of relocating Wuhan station in 2010 was 8%; 2)The annual average relative humidity in Wuhan urban area kept in a high level, and the values were between 75%-85%, of which Wuhan station was the highest; 3) Relative humidity increased from January to June gradually, but after reaching peak value in June, it began decreasing in a larger speed, and the monthly differences were only between 0.1%~2.5%. the seasonal characteristics of relative humidity of Wuhan urban area is that the RH of summer is the highest in the whole year, RH of winter is the lowest; 4) From 1961 to 2015, the average relative humidity of Wuhan urban area showed a long-term decreasing trend, and the linear trend was accelerated after the 1990s; 5) In the past 55 years, average relative humidity series of spring, autumn and winter all showed declining trends in varied degrees, of which spring was more obvious, more obvious rising trend was found for summer, but the value of annual and four seasons are showing a significant downward trend after 1991.
