Why can someone "call the wind and call the rain" by the lake in Yunnan?

Gaoligong Mountain, on the west bank of Nujiang River in Yunnan, China, is located in the subtropical mountainous area. Because of the high mountain, there are often snow glaciers on the top of the mountain, and the melting ice water merges into dozens of lakes embedded in the vast forest. But there is a puzzling phenomenon in these lakes.

These lakes are strange because of who stands by the lake and speaks loudly or makes other noises (such as gunshots). ) will make the originally clear sky cloudy and stormy in an instant.

Some people speculate that this is related to the local topography and climate conditions. April-May to 165438+ 10 is the rainy season every year, and the air humidity is very high at ordinary times. When the temperature rises in summer, the temperature over some valleys can be as high as 40℃, which makes it possible to maintain extremely high humidity in the air. However, the temperature of the lake here is very low because of the snow on the top of the mountain, thus maintaining a low temperature layer on the lake. Because these lakes are located in the lower part of the valley, there is little wind at ordinary times, which makes the low temperature layer of the lakes and the high temperature and high humidity air layer above them maintain an extremely unstable balance. Therefore, once there is external sound wave impact, it will lead to severe convection in the upper and lower air layers, resulting in strong winds; Hot air with high humidity meets cold air and quickly condenses into water droplets, leading to heavy rain. But whether this speculation is correct or not needs further investigation and confirmation.
