Quarterly Temperature Patterns Across China: A 2016–2023

This study investigates the spatial and temporal dynamics of temperature variations across China from 2016 to 2023 utilizing ERA5-LAND temperature data. The analysis reveals pronounced regional differences in temperature distribution, with colder conditions prevailing in northern and western China during winter, contrasted by warmer temperatures in the south. The long-term trend shows a gradual decline in monthly mean temperatures despite clear seasonal fluctuations. Additionally, the quarterly analysis identifies a faster rate of warming during the first half of the year, particularly in the cooler months, while the fourth quarter shows minimal change. These findings underscore the complexity and heterogeneity of climate responses across different regions and seasons in China, suggesting that localized climatic changes are driven by both global climate forces and regional factors.
