The weather in Bama is very hot.

Because China is located in the northern hemisphere, and most areas are located in the northern temperate zone. Temperate zone is characterized by warm winter and cool summer. Except for Kunming, which is influenced by the trade winds, China is like spring all the year round. Guangdong, Hong Kong, Macao and Taiwan are located in the tropics, while other places are characterized by temperate zones. Moreover, the height angle of the sun is the largest in summer, and the sun shines almost directly on the earth. Solar energy reaches the earth with the most heat, and the earth gets more energy from the sun, so it is hot in summer. Because the revolution of the earth around the sun is an ellipse, in winter, our earth just rotates to the apohelion, far from the sun, and gets less heat. In summer, the earth just rotates to the perihelion, which is close to the sun and gets more heat. So it's normal to be warm in the east and cool in summer. The so-called calm and natural cool, don't heat yourself up.
