The urban warmer phenomenon has become more obvious with the process of urbanization and the influence of wind environment and climate pattern in urban areas on urban high temperature is very important In this study the calculation of the land rough length is applied by calculating the rough length of the city to predict the wind environment in Tainan At the same time the high-density street-level air temperature observation network (HiSAN) is also used to explore the characteristics of the wind and thermal environment in Tainan The results show that the large water area in the daytime will obviously cool down the surround area At night the green area will have a significant cooling effect on air temperature The urban composition factors will have different effects in different time periods At the same time climatic conditions will also affect the difference in the distribution of high temperature The daily temperature difference will cause the high temperature to be located in more inland and the wind field in the large environment will cause the difference between high temperature in north and south side According to the above results urban impact factors of thermal environment include: urban composition factors climatic conditions and different time periods In the future when faced with the situation of hyperthermia the mitigation strategy should consider the interaction between more different parameters in a specific time period
