摘要
温度和降水是反映气候变化的两个主要变量。因此,针对这两个变量序列的时空分辨率和已揭示的气候变率,以及需要进一步研究的方向作了初步的归纳与讨论。用近一个世纪的温度、降水资料揭示,中国东部地区存在着准20a和准70a的振荡以及中国降水气候型的漂移;用近五百年和近千年的代用序列并结合器测资料,揭示了我国东部地区存在着70～80a的振荡。文章最后指出,我国气候变化研究在资料开发、规律与机理研究、预测与服务等方面有待进一步提高。
Temperature and precipitation are the two main variables in climate change. Spatial-temporal resolutions of temperature and precipitation, and climate variability are summarized and discussed in this paper. Recent 100- year datasets are used to reveal quasi-20-year and quasi-70-year oscillations in eastern China, as well as precipitation pattern shift in China. Besides,70- to 80-year oscillations exist in eastern China, based on 500 years and 1000 years proxy and observation records. Finally, researches for future on climate change in China should be improved on data development, regularity and mechanism, prediction and service.
