Climate Change in China: An Analysis of Temperature and Precipitation Variations Across 2367 Meteorological Stations (1981-2020)

Abstract

This study aims to examine the changes in climate across China from 1981 to 2020, focusing on both spatial and temporal variations. The analysis utilizes data collected from 2367 meteorological stations throughout the country. The findings of this research indicate an overall warming trend across China, with more significant temperature increases observed in the northern regions. However, the changes in precipitation patterns were more complex. While southern areas experienced greater rises in precipitation, some inland regions witnessed decreases. Further investigation into seasonal and monthly variations revealed substantial variability in both warming and precipitation patterns across different regions and timeframes. Surprisingly, the study found that the relationship between geographical factors such as latitude and altitude and the extent of climate change was relatively weak, except in arid Xinjiang. Although this research provides a comprehensive overview of climate change in China, it also emphasizes the necessity for more localized studies. These localized studies would help in understanding the multifaceted factors that drive the observed changes. By conducting more focused research, people can gain a deeper understanding of the specific influences and impacts of climate change in different regions of China.
