Causes of the formation of the sea of clouds on Mount Huangshan: low clouds and ground fog formation.

Huangshan mountain high valley low, lush forests, short sunshine, water is not easy to evaporate, thus high humidity, water and gas. After the rain is common wisps of light fog, rising from the valley. The average annual fog day 250 days or so, can be called the home of the clouds. Huangshan sea of clouds is formed by low clouds (cloud bottom height below 2500 meters) and ground fog.

Low clouds are mainly stratocumulus, which is its characteristics. Between November and March every year, 97% of the sea of clouds in Mount Huangshan are formed by stratocumulus clouds, and only 3% are formed by stratocumulus clouds or fog. from June to September, there are light cumulus clouds and thick cumulus clouds forming the sea of clouds, which account for about 6% of the total sea of clouds in this period.

In the winter and spring seasons, the temperature in the lower and middle layers of the atmosphere is low, the condensation height of stratocumulus clouds is low (about between 800 and 1,200 meters), and there is frequent cold air activity. Process weather activity is obvious, after the rain and snow, there are often large areas of good cloud sea, especially the spectacular sea of clouds sunrise.

After the summer gradually into the rainy season, with rising temperatures, the cloud condensation height rises to about 1500 meters, the height of the clouds more than or close to most of the peaks, which is not easy to see the sea of clouds. july to august, for the Huangshan summer, this period is often controlled by the Pacific subtropical high pressure, the temperature rises, the low clouds of the condensation height also rises to the highest height of the whole year.

Huangshan Mountain sea of clouds geographic division:

One of the Huangshan Mountain East Sea

Located in the White Goose Peak, Xanadu Peak to the east. Including the White Goose Ridge under the Grand Canyon and the area around the Pippin. East China Sea is not as wide as the South China Sea, the North Sea, but the mountain cliffs and deep valleys, the wind and clouds, more unpredictable. With the valley wind of the circulation movement, the clouds roll rapidly, as the waves, surging, also has the momentum and characteristics. Gongyang foothills of the "five old swinging boat", more realistic in the sea of clouds.

Two, Huangshan South China Sea

Located in the south of the two main peaks of Tendu, Lotus. Here, high peaks and deep gully, often cloudy and parallel into a vast sea of clouds. To its position known as the "South China Sea", also known as the "former sea". This area, the sea of clouds is vast, countless peaks sunk to the bottom of the sea, only Zhu Sha peak, the old man peak, purple stone peaks and other peaks tip exposed to the sea, such as islands in the sea.

Three, Huangshan West Sea

Located in the Danxia peak, Feilai peak on the west side. Thousands of ren walls, ten thousand ravines, magnificent West Sea Grand Canyon is here. It is also the most beautiful and deepest part of the Huangshan Mountain Scenic Area. The best place to see the West Sea is at Paiyun Pavilion. In front of the Paiyun Pavilion, the wall is thousands of feet high, and the cloudy atmosphere is a perfect place to appreciate the sea of clouds, the evening sunset and the strange peaks and valleys.

Four, Huangshan North Sea

Located in Danxia, lion, north of the first letter peak. In the distance are the vast fields of the former Taiping County. The north side of Lion Peak and Shixin Peak is steep, and between the cliffs and valleys, a sea of clouds often appears.

Because of the complicated terrain, the airflow constantly encounters obstacles as it traverses between the mountains, forming a circulation from the valley winds, which sometimes rises and sometimes falls in the deep ravines. Clouds followed up and down, circling and fluttering or diffuse and stretch, as the waves rise and fall, waves fly and surge. In the early hours of the morning, the red sun rises in the east, the sunlight, irradiating the sea of clouds, colorful, and even more wondrous.
