| 摘 要： | 应用1960～2009年逐日气象记录,在对观测资料进行均一化处理的基础上,分析北京地区极端气温的时间变化特征及其对城市化的响应过程.结果表明,过去50 a北京极端最高、最低气温分别以O.23℃/10 a以及1.02℃/10 a的线性倾向率显著增加,在1988年前后存在明显的增暖性突变.1997～2009年间北京高温日数...

| Abstract: | High quality data series are not only the base of our study on climate change,but also the base of the diagnosing,forecasting and valuating climate.Because of sites moving and observation method changing,the climate data have been inhomogeneity for a long time.The original data applied in this paper sourced from Beijing meteorological information center,and were homogenized by the method of MASH(Multiple Analysis of Series for Homogenization).The MASH package consists of an interative procedure designed to ... |
