Extension: The latitudes of Lhasa in China and Chongqing are similar, but the temperature in summer is quite different. The city with lower temperature is (). What is the main reason?

Next: Lhasa. Cause: High altitude and low temperature.

(1) Hengduan Mountain has low latitude and high altitude. At the foot of the mountain, it belongs to the subtropical climate zone. With the increase of altitude, the temperature drops, forming various climate zones. Different days in ten miles are also due to different altitudes and different air pressures, resulting in different weather conditions.

(2) It won't snow. Because the temperature drops by about 0.6 per 100 meter. 3800 minus 1800 equals 2000 meters. The temperature of 2000 meters is about 12 degrees, so the temperature is about 6 degrees, which can't reach the temperature of snow.
