摘要
基于全国、西南及其不同省市区多年实测气温、降水资料和NCEP/NCAR再分析数据,以及国外一些气候中心资料,采用多种方法对于不同尺度温度和降水长序列的变化进行分析.西南地区的气候变化,持续增温和降水的持续减少,自上世纪60年代以来干旱化趋重,西南地区的温度和干旱变化,和全国一样,受制于系列气候环境物理场中各种物理机制和影响.启示人们需要基于气候环境变化,特别关注未来西南的气候变化走向.
The long term changes in temperature and precipitation series on different scales are analyzed with a variety of methods on the basis of many years’data of the measured temperature,precipitation and the NCEP/NCAR reanalysis result for China,the southwestern China and different provinces,and the data from some foreign climate centers.Since the 1960s,southwest China has seen a drying trend in climate change with sustained increase in temperature and steady decline in precipitation.Temperature changes and drought in southwest China,like other parts of the country,are subject to the physical mechanism and influence of various physical fields in series climate environment,drawing people’s attention to the climate change trend in this area.
