The Liuyun Waterfall in Lushan Mountain pours into the world like Tianhe. What causes the sea of clouds?
A sea of clouds refers to clouds formed under certain conditions. The sea of clouds usually occurs from June 165438+ 10 to April of the following year, that is, winter and spring. During this period, the air temperature in the middle and lower layers is low, and the condensation height of stratocumulus is relatively low, which usually drops to about 800 ~ 1200m. There are frequent cold air activities in winter and spring, and a large area of good sea of clouds often appears after rain and snow, especially the spectacular sunrise of the sea of clouds. The temperature in Xia Hou is rising gradually, and the cloud condensation height rises to about 1500m, which basically exceeds or approaches most of the peak values. At this time, the clouds are shrouded and it is not easy to see the sea of clouds. If you want to see the spectacular sea of clouds, you'd better choose higher peaks and watch them in winter and spring. In China, the famous clouds are Emei Mountain, Lushan Mountain, Taishan Mountain and Huangshan Mountain. The sea of clouds in Lushan Mountain is the first wonder of Huangshan Mountain. It looks like the sea but it is not the sea. The clouds on the mountain peak are unreal and colorful, which is amazing.
Second, after the rain, you can often see the unpredictable sea of clouds on the mountain. It is near turquoise, coming and going, and it is full of affection; Sometimes it rolls, the smoke waves are vast, swallowing mountains and rivers. The sea of clouds seen in Lushan Mountain is low clouds and clouds on the ground. Most of these clouds are stratocumulus clouds, and the thickness is about tens to three or four hundred meters. The clouds are even and tidy, which looks spectacular from a distance. The formation of the sea of clouds depends on the topography and climatic conditions of the mountains. Lushan Mountain is located in the subtropical humid climate zone, and the towering peaks block the flow of warm air, raise the suspicious clouds and lead to rainfall, forming a foggy, low-cloud and abundant precipitation climate. Is the sea of clouds in Huangshan divided by geographical location? Qianhai? 、? Houhai Donghai? 、? Xihai? 、? Tianhai? Big five? Sea area? . These sea of clouds areas are surrounded by mountains on three sides, and the deep valleys are wide and steep, which makes the water vapor easy to condense and maintain, and also makes the mountain scenery sea of clouds unique. Different from other mountains, seas and clouds, it is surrounded by strange peaks and dangerous cliffs, cleverly decorating the fleeting dreamland of Lushan Mountain and dyeing the fantastic colors of Huangshan Mountain. The sunrise and sunset of Lushan Mountain are mostly set in the sea of clouds, which is magnificent and spectacular.
The sea of clouds is formed by low clouds and ground fog. Lushan Mountain has a high valley, lush forests, short sunshine time, and water is not easy to evaporate, so it has a high humidity and a lot of water vapor. Therefore, especially after the rain, you can often see wisps of light fog rising in the valley. Lushan Mountain has an average of about 250 foggy days all year round, which is a land of fog and mist. Low clouds are mainly stratocumulus. In winter and spring, the air temperature in the middle and lower layers is low, the condensation height of stratocumulus is low, the cold air activity is frequent, and the process weather activity is obvious. So after the rain and snow, it is easy to see a large sea of clouds.
