Reasons for the large temperature difference between day and night in Bamei Village

1. Altitude: Bamei Village is located in a high altitude area. Altitude will lead to the decrease of atmospheric pressure, air density and heat conduction. During the day, the sun shines directly on the ground, and the ground is subjected to strong sunlight and thermal radiation, resulting in an increase in temperature. At night, the ground dissipates heat quickly, the temperature drops quickly, and the temperature difference between day and night is large.

2. Weather conditions: The air in Bamei Village is relatively dry and there are few clouds. During the day, the sun shines directly on the ground, and there is no cloud cover, resulting in more sunlight and thermal radiation on the ground, and the temperature rises rapidly. There are few clouds at night, the ground dissipates heat quickly, and the temperature drops rapidly, further increasing the temperature difference between day and night.
