Surface air temperature change in the Wuyi Mountains, southeast China

  • Detecting changes in surface air temperature in mid- and low-altitude mountainous regions is essential for a comprehensive understanding of warming trend with altitude. We use daily surface air temperature data from 64 meteorological stations in Wuyi Mountains and its adjacent regions to analyze the spatio-temporal patterns of temperature change. The results show that Wuyi Mountains have experienced significant warming from 1961 to 2018. The warming trend of the mean temperature is 0.20℃/decade, the maximum temperature is 0.17℃/decade, and the minimum temperature is 0.26℃/decade. In 1961-1990, more than 63% of the stations showed a decreasing trend in annual mean temperature, mainly because the maximum temperature decreased during this period. However, in 1971-2000, 1981-2010 and 1991-2018, the maximum, minimum and mean temperatures increased. The fastest increasing trend of mean temperature occurred in the southeastern coastal plains, the quickest increasing trend of maximum temperature occurred in the northwestern mountainous region, and the increase of minimum temperature occurred faster in the southeastern coastal and northwestern mountainous regions than that in the central area. Meanwhile, this study suggests that elevation does not affect warming in the Wuyi Mountains. These results are beneficial for understanding climate change in humid subtropical middle and low mountains.
