There are colorful clouds in Changsha. What wonderful clouds have you seen?

Hole-piercing cloud, also known as hole-piercing cloud, is a great wonder of nature. It refers to a cloud hole with a diameter of several hundred meters, which is shaped like the scene of an alien spaceship invading the earth in the sci-fi blockbuster Independence Day. When propeller planes or jet planes pass through suitable atmospheric conditions, they will condense liquid water droplets and immediately fall like snowflakes, forming circular cracks, forming cloud holes and making them produce rainfall. Together with cirrus clouds, pod cumulus clouds, hat clouds, horseshoe vortex clouds, milky clouds and spray clouds, they are called the top ten strange cloud landscapes. On 20 15 65438+ 10 19, a cloud cave appeared over Fuyong, Shajing and Zhuhai in Baoan, Shenzhen.

Second, cirrus clouds

Turbulent cumulus clouds formed downwind at the top of a large mountain range, in which the airflow rotates around an axis parallel to the mountain range. Cirrus clouds are horizontal tubular clouds, and their appearance usually indicates the arrival of storms, and they rarely appear at the end of storms. When in storm warning, the downward cold air will spread to form cirrus clouds. This rapidly sinking air mass can attack the land surface, and its powerful airflow can reach a very long distance. Cold air will slide under the hot air layer, and then be sucked up by the vertical updraft of the storm, and then cirrus clouds will condense the water vapor in the hot air to form clouds. Eventually, cirrus will separate from the main clouds of the storm. Cirrus clouds are very dangerous. According to the measurement, the velocity of updraft and downdraft generated by cirrus cloud exceeds1500m per minute.

3. Podlike cumulus clouds

Clouds, such as lenses or pods, have obvious boundaries and are often connected by many individuals. Pod-shaped cumulus clouds are stable and moist clouds that are lifted to high altitude, and the water in them condenses to form clouds. If the dry and wet air layers exchange, the cloud will form a vertical structure. Podlike cumulus clouds are usually formed where there is updraft in the lower part and downdraft in the upper part. Once it passes through the obstacle, the lenticular cloud will return to its original state and form a standing wave shape in the air, which is located on one side of the mountain range. As shown in the picture, this is a lenticular cloud in the Rainier Mountains in Washington, USA.

Fourth, the waves turn over the clouds.

Wave cloud is a great wonder of nature, which refers to a kind of cloud that can form a miniature wave peak. When this cloud structure extends down to the island, it is like a ripple left by a ship crossing the water surface, extending for hundreds of kilometers, and finally mixing with the cumulus edge in the north. Together with perforated clouds, cirrus clouds, pod cumulus clouds, hat clouds, horseshoe vortex clouds, milky clouds and jet clouds, they are called the top ten fantasy cloud landscapes.
