Why is the temperature in Hohhot lower than that in Beijing and the weather colder than that in Beijing? It's urgent, about 300 words, one paragraph.

It's simple. 1 Hohhot has a higher latitude than Beijing. The higher the latitude, the colder the weather. 1 Beijing is a national big city, and the urban thermal effect is very strong, which is also commonly known as the greenhouse effect. The geographical location of Beijing determines its temperature. There is Daqing Mountain in Hohhot to block the cold air from the north. But the back of Daqing Mountain, that is, the north is 5~8 degrees colder than Hohhot, and the worst can reach 10 degrees. Beijing is located in the Yanshan Mountains. Did your train to Beijing pass through many caves on the way? Most cars can't see mountains and deep ditches when they leave Badaling. This blocks some cold air. And our calls to the city only blocked the north. There is air leakage in the east, west and south.
