It seems sunny at the foot of the mountain, but it starts to rain halfway up the mountain. Why is the weather different down the mountain?
The difference in weather between the mountains and the mountains is mainly due to the influence of terrain and altitude.
1. The influence of terrain: The terrain at the foot of the mountain is flat, without the obstruction of mountains, the atmospheric circulation is relatively good, the air humidity is relatively high, and it is easy to form low clouds, fog, haze and other weather conditions. Halfway up the mountain, the mountains begin to tower, the terrain is complex, and atmospheric circulation is hindered. The air is relatively thin and the humidity is relatively low, making it easy to form clouds and rainfall.
2. The influence of altitude: As the altitude increases, the temperature and air pressure decrease, the air is relatively thin, and the humidity is relatively low. Such climate and environmental conditions are very beneficial to the formation of clouds and the occurrence of rainfall. . At the foot of the mountain, the altitude is relatively low, the air pressure and temperature are relatively high, the air is relatively dense, and the humidity is relatively high. Such climate conditions are not conducive to cloud formation and rainfall.
