Why is Datun hotter than the old one?

According to Pearl.com, the reason is the difference in geographical location and altitude.

1. Datun is located in the north of China, which belongs to the temperate continental climate zone, with high temperature in summer, while Gejiu is located in the southwest of China, which belongs to the subtropical monsoon climate zone, with relatively moderate temperature in summer.

2. The altitude of Datun in Beijing is relatively low, about 55 meters. Gejiu is located in Yunnan Plateau, with an average elevation of more than 900 meters. Low altitude areas are more susceptible to heat waves and high temperatures, so the temperature in Datun, Beijing is higher in summer.
