Why is Zhengzhou so hot? Is it because of the climate?

There are many reasons for urban temperature, including climate, urban architecture, urban greening and other factors. Urban fever may be caused by the following reasons:

1. Zhengzhou has a continental monsoon climate in the north temperate zone, with moderate cold and warm, four distinct seasons, drought in spring, hot and rainy in summer, abundant sunshine in autumn, cold and rainy in winter, the longest in winter, followed by short in spring. Therefore, due to climatic reasons, the temperature in Zhengzhou in summer will be particularly high.

2. Zhengzhou has dense buildings, and asphalt roads and cement pavements have higher heat absorption rate and smaller specific heat capacity than the soil and vegetation in the suburbs, which makes the urban area heat up faster and radiate to the surrounding areas and the atmosphere, causing the urban area temperature to be generally higher than that in the surrounding suburbs at the same time, and the high-temperature urban area is surrounded by low-temperature suburbs, resulting in a higher overall temperature in Zhengzhou, which is the so-called heat island effect.

3. Heat dissipation of cars and air conditioners. The high population density in Zhengzhou will lead to the increase of man-made heat emission. For example, when people drive and blow air conditioners at home, it will lead to huge heat dissipation, so the temperature in Zhengzhou will rise, which makes people feel very hot.
