The time-lapse footage taken by the reporter in Lijiang shows that the colorful clouds in the sky are elegant and dynamic, like a flowing rainbow.
How did the colorful cloud come into being?
What kind of weather conditions can create the beautiful "Colorful Clouds"
According to experts, what we usually call colorful clouds is called iris in meteorology. It is a natural phenomenon produced by the sun's rays and ice crystals in the cloud, and it is a typical "
sunflower
" phenomenon.
Generally appear in the winter and spring seasons of Yunnan, which is the dry season. Altocumulus and altostratus clouds are easy to appear, the cloud cover is thin, and the sunshine hours are more than summer, and the colorful auspicious clouds have a relatively high probability.
Under suitable weather conditions, the sun's rays form an appropriate angle with the clouds. When the sun's rays pass through the clouds, through refraction and reflection, the water vapor in the clouds above separates the sun's spectrum, thereby scattering the colorful rays of light and forming colorful clouds.
It usually appears in the afternoon or early morning.
Guo Rongfen, Senior Engineer, Yunnan Meteorological Bureau: Mainly
green and light orange-red, soft tones, and visually warm and peaceful.
However, the formation conditions are more demanding. It usually occurs in places with 10 degrees or 40 degrees of vision around the sun. Sunlight forms a suitable angle with the clouds. The sun is shot obliquely or even parallel to the clouds. In addition, the water droplets or ice crystals that make up the clouds are generally It should be of moderate size and relatively uniform.
Yunnan is located in a low-latitude plateau, with large undulations and the easiest to form a colorful cloud landscape.
According to experts, the appearance of various peculiar cloud patterns is inconsistent with local topography and local air currents in the atmosphere, that is, uneven distribution of wind speed and humidity in high and low layers, atmospheric fluctuations, turbulence, dry air and other factors "coincidentally". form.
Guo Rongfen, Senior Engineer, Yunnan Meteorological Bureau: The
reason why it is called Yunnan is the south of
colorful
clouds.
What other strange clouds in nature?
Whenever we look up at the sky, nature always brings surprises, such as colorful clouds with great ornamental value, as well as waterfall clouds, grape clouds, etc. The peculiar cloud shape can always arouse people's beautiful imagination.
Affected by the cold air going southward, at the end of November last year, the first waterfall cloud landscape appeared in Lushan, Jiangxi.
The sea of clouds in Lushan Mountain is known for its "white as snow, light as silver, floating like cotton, soft as cotton, and broad as the sea".
The cascade cloud is pressed by the wind from afar and rushes into the scissors canyon.
The sea of clouds opens and closes, gathers and disperses, and changes suddenly, just like a fairyland in the clouds.
Just before that, in late June 2020, a peculiar "grape cloud" appeared over Iraq. Each cloud raised like a grape and filled the entire sky. According to meteorological experts, this kind of cloud is called "hanging ball cloud" or milky. Clouds, also known as milky cumulus clouds, usually appear below cumulonimbus clouds. This peculiar cloud shape is formed when the colder air in the sinking air meets the warmer air in the updraft, which is a rare wonder in nature .
Guo Rongfen, Senior Engineer, Yunnan Meteorological Bureau:
Because milky clouds are more connected than cumulonimbus clouds, they are prone to thunderstorms, heavy rain or heavy rain
In addition, luminous clouds often appear in high latitudes of the earth.
Clouds look like water waves, like the sea floating in the sky, and some emit light. This kind of celestial phenomenon is more common in summer, and sometimes luminous clouds can be seen in low latitudes.
According to experts, the essence of luminous clouds is that water vapor in the upper atmosphere condenses into ice, which emits color by reflecting the light of the sun.
Which peculiar cloud patterns appear with meteorological disasters?
In addition to providing us with the enjoyment of beauty, nature also warns humans of the arrival of meteorological disasters through peculiar cloud shapes.
In March 2017, a funnel cloud appeared near Edda, Oklahoma, in the central United States. It looked like a small tornado, named after its rapidly rotating funnel-shaped structure.
Severe weather such as storms and hail occurred in Oklahoma and parts of northern Texas that day.
Guo Rongfen, Senior Engineer, Yunnan Meteorological Bureau:
Funnel cloud is an important basis for judging tornado weather, and it will bring a series of severe weather.
How did the "Long Cloud" over Beijing-Tianjin-Hebei come into being?
In addition to the peculiar cloud type that nature brings us, there is another kind of cloud that is artificially created and has a hard core cause.
On December 7, 2019, long strips of dragon-shaped clouds appeared in the sky in Beijing, Tianjin, Hebei and other places, winding endlessly, which was amazing. Netizens took photos of them as auspicious dragons.
However, this "dragon" is not formed naturally. It belongs to the trail cloud. It is the wake left by the fast boat rocket launched that day. After being illuminated by the high-altitude sunlight, it appears as a dragon in the picture, shocking To the netizen.
Due to the extremely high altitude of the rocket, it can be observed in many places in Beijing, Tianjin and Hebei.
