It has been demonstrated that climate change is an established fact. A good comprehension of climate and extreme weather variation characteristics on a temporal and a spatial scale is important for adaptation and response. In this work, the characteristics of temperature, precipitation, and extreme weather distribution and variation is summarized for a period of 60 years and the seasonal fluctuation of temperature and precipitation is also analyzed. The results illustrate the reduction in daily and annual temperature divergence on both temporal and spatial scales. However, the gaps remain relatively significant. Furthermore, the disparity in daily and annual precipitation are found to be increasing on both temporal and spatial scales. The findings indicate that climate change, to a certain extent, narrowed the temperature gap while widening the precipitation gap on temporal and spatial scales in China.
已经证明气候变化是一个既定事实。在时间和空间尺度上很好地理解气候和极端天气变化特征对于适应和应对气候变化非常重要。在这项工作中，总结了 60 年来温度、降水和极端天气分布和变化的特征，并分析了温度和降水的季节性波动。结果表明，无论是在时间还是空间尺度上，日温差和年温差都在缩小。然而，差距仍然相对显著。此外，还发现无论是在时间尺度还是空间尺度上，日降水量和年降水量的差距都在增加。研究结果表明，气候变化在一定程度上缩小了中国时间和空间尺度上的温度差距，同时扩大了降水差距。
