摘  要:
根据西宁地区4个地面气象观测站的水汽压观测资料,运用线性回归、Mann-Kendall和R/S方法对近地面水汽变化特征进行年际气温、突变和未来变化趋势分析。结果表明:西宁地区近地面水汽压月变化表现为"单峰"型,1月是一年之中水汽含量最少的月份,在7月达峰值。近43a来西宁地区冬季水汽含量增加趋势显著,年及其他季节水汽压变化趋势不明显;近地层水汽含量在1982年发生了突变,西宁地区年和四季水汽压存在明显的Hurst现象,除夏季的水汽压(较弱)外其他季节的气温均表现出十分强劲的势头;水汽含量对气候变暖响应明显。秋、冬季水汽含量变化与平均气温有显著性正相关。

摘  要:
According to vapor pressure observation data of four ground- based observatory in Xining,by using linear regression,Mann Kendall and R / S method on the surface moisture variation characteristics to analyze trends,mutation,and the future trends. The results show that,near surface monthly variation of vapor pressure presented " unimodal type" in Xining,lowest in 1 Jan,reach peak in July. In recent 43 years,Winter water vapor content increased significantly,but unconspicuous in year and other seasons. Near- surface vapor content happened a mutation in 1982,the vapor pressure of year and four seasons obvious Hurst phenomenon,in addition to the summer water vapor pressure( weaker) other seasonal temperatures showed a strong momentum.Water vapor content responded obviously to climate warming. The water vapor content change of year,autumn and winter had significant positive correlation with average temperature.
