Abstract: 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.
