Abstract:

This study selects daily observational data from 15 national meteorological stations in Xinzhou city of Shanxi province from 1971 to 2020. Using methods such as the linear trend rate, moving average, and Mann-Kendall sudden change test, it analyzes the characteristics of changes in the climate comfort of residential environments in Xinzhou city. The results indicate that the overall climate comfort of the residential environment in Xinzhou city is cold, with June to August being the comfortable months and July being the most comfortable month, totaling 102.2 comfortable days per year. From 1971 to 2020, both the wind efficiency index and the temperature-humidity index in Xinzhou city showed significant upward trends, with sudden increases in 1986 and 1997 respectively, enhancing the residential environmental comfort. The climate comfort in Xinzhou decreases with increasing altitude, as does the number of comfortable days. The comfort level is relatively higher in the Wutai Mountain scenic area from late May to early September, with July being the most comfortable. Overall, the climate comfort zones and relatively comfortable zones in Xinzhou city are located in the lower-altitude areas of the Xinding Basin and along the Yellow River, while the less comfortable areas are in the high-altitude cold mountain regions.

Key words: Altitude, Climate comfort, Temperature-humidity index, Wind efficiency Index
