The change of urban heat island effect in Quanzhou central city under different meteorological conditions feature research

Based on the meteorological data of Fengze District from March 2021 to February 2022 and March 2024 to February 2025, which represents the meteorological data of the central urban area of Quanzhou, this paper analyzes and elaborates in detail the changes of urban heat island intensity under typical meteorological conditions such as precipitation, air pressure, relative humidity, wind level, and wind direction. The results show that the urban heat island effect in Quanzhou has obvious seasonal variation characteristics. Among them, spring is stronger and winter is weaker. Under different meteorological conditions, the intensity of urban heat island in Quanzhou shows obviously different fluctuations, and the intensity of urban heat island varies greatly. Among them, the precipitation is mainly negatively correlated with the heat island intensity. When the wind speed is second and below, it is most conducive to the maintenance and development of the heat island effect in the central urban area of Quanzhou, and the heat island intensity is also the largest.
