The origin of Huangshan sea of clouds
Huangshan Mountain has high valley, dense forest, short sunshine time and difficult evaporation of water, so it has high humidity and much water vapor. After the rain, wisps of light fog often rise in the valley. There are about 250 foggy days on average throughout the year, which is really a land of fog. The sea of clouds in Huangshan is formed by low clouds (the height of the cloud bottom is less than 2500 meters) and ground fog.
Low clouds are mainly stratocumulus clouds, which is its characteristic. From June165438+1October to March of the following year, 97% of the sea of clouds in Huangshan was formed by stratocumulus, and only 3% was formed by stratocumulus or fog. From June to September, there are clouds formed by light cumulus clouds and thick cumulus clouds, accounting for about 6% of the total cloud amount in this period.
In winter and spring, the air temperature in the middle and lower layers is low, the condensation height of stratocumulus is low (about 800 ~ 1200m), and cold air activities are frequent. The weather activity is obvious during the process. After rain and snow, there will often be a large area of good sea of clouds, especially the spectacular sunrise of the sea of clouds.
In the rainy season after summer, with the temperature rising, the condensation height of clouds rises to about1500m, and the height of clouds exceeds or approaches most peaks. At this time, the clouds are shrouded and it is difficult to see the sea of clouds. July-August is the midsummer of Huangshan Mountain. During this period, it is often controlled by the Pacific subtropical high, the temperature rises, and the condensation height of low clouds also rises to the highest level in the whole year.

Geographical division of Huangshan sea of clouds:
I. Huangshan Donghai
Located to the east of White Goose Peak and Xiandu Peak. Including the Lower Grand Canyon in Berlin and the area around Pippen. Although the East China Sea in China is not as vast as the South China Sea and the North China Sea, it is steep and deep, and even more unpredictable. With the circulation movement of the valley wind, the clouds roll rapidly, like stormy waves, surging, with momentum and characteristics. The "five old boating" at the foot of Yanggong Mountain is more realistic in the sea of clouds.
Second, Huangshan Nanhai
Located in the south of the two main peaks of Tiandu and Lianhua. There are high peaks, deep valleys and clouds, forming a vast sea of clouds. Its location is called "Nanhai", also called "Qianhai". There is a vast sea of clouds in this area, and countless peaks sink to the bottom of the sea. Only the peaks such as Zhusha Peak, Laoren Peak and Zishi Peak are exposed to the sea, and they are among the islands like the sea.
Third, Huangshan West Sea.
Located on the west side of Danxia Peak and Feilai Peak. The towering Grand Canyon of the West Sea is here. It is also the most beautiful and profound part of Huangshan Scenic Area. The best place to see the West Sea is Paiyun Pavilion. Paiyun Pavilion, cliffs and dense clouds are excellent places to enjoy the sea of clouds, sunset glow and strange peaks and valleys.
Fourth, Huangshan Beihai
Located in the north of Danxia, Lion and Shixinfeng. In the distance is the vast fields of the former Taiping County. The terrain on the north side of Lion Peak and Shixin Peak is steep, and there are often clouds between cliffs and valleys.
Due to the complex terrain, the airflow constantly encounters obstacles when passing through the mountainous area, forming a circulation from the mountain valley wind, which sometimes rises and sometimes falls in the deep valley. Clouds move up and down, dancing or scattering, just like the ups and downs of the waves, the waves fly. In the morning, the red sun rises and the sea of clouds is illuminated by the sun. Colorful, more spectacular.
