Volcanic cloud computing power
A cloud of ash and other fine debris from an eruption. Volcanic ash is formed when volcanic clouds spray down
When a volcano erupts violently, it proces clouds that are very similar to cumulus clouds, because heat and water vapor dissolve into the atmosphere from the ground. However, because the cloud contains a lot of volcanic ash, volcanic debris and st, it is often brown or polychromatic appearance, making it different from ordinary thunderstorms
when the heat from the eruption enters the atmosphere, cumulus and tower clouds will form at the top and around the volcano. When the ash rises very high, and finally reaches the stagnant (stratosphere), where the upward trend stops, then the top begins to flatten and scatter around, much like a cumulonimbus cloud. The extreme chaos, together with the highly saturated material inside, proces a bright flash
when the volcanic eruption is not strong, or the atmosphere is very stable, the volcanic cloud will not rise too high, and it is very similar to the plume of smoke from a big chimney, and it will spread horizontally around after a short rise
in the vicinity of volcanoes, heavy volcanic ash and volcanic debris will proce rainfall from the clouds. For the observer, the curtain like clouds are similar to rain clouds or streamer like clouds, and fine st will form in a very long distance; Blur the sky and distant objects
height
volcanic clouds can reach 60000 feet (18000 meters), depending on the power of the eruption
range
in volcanic active areas, indivial volcanic ash will drift around in high space
season
the whole year. The horizontal drift of volcanic clouds is the most in winter
characteristics
volcanic clouds can stay in the lower stratosphere for several months, resulting in a short-term drop in global temperature. Near the eruption site; Volcanic ash can affect human health, cause respiratory allergies, and also cause damage to machinery, especially for machinery that needs a lot of air, such as air conditioners, harvesters and cars. However, volcanic ash is also rich in nutrients, which can make the soil fertile and concive to the growth of crops
diversity
the actual shape of volcanic cloud depends on the power of volcanic eruption, the material contained in the volcanic ash cloud, and the rising direction of the volcanic cloud in the atmosphere. The most severe volcanic eruption will proce cumulonimbus like clouds, while the weaker volcanic eruption will proce stratus like clouds
In the following hours, the volcano erupted as many as six times, and the hot volcanic cloud swept the whole Pompeii, where people and animals were not spared. People on the verge of death cry, struggle, and beg for the coming of the God of protection. Unfortunately, this time the darkness has really come to the world
Open classification: nature, natural phenomenon, volcano, climate
volcanic clouds
distribution: this effect can affect the world
height: volcanic clouds can diffuse from the surface to 18000m altitude
cause: volcanic clouds are formed ring volcanic eruption. When a volcano erupts, it releases huge energy, which will arouse strong convective activities near the crater, thus forming a "volcanic cloud". According to the release of huge energy and heat, it can be concluded that many volcanic clouds are strong convective snow and rain clouds. When the volcanic cloud appears at night, although the outline of the cloud is not very clear, the lightning is as spectacular as a silver snake
associated weather: volcanic clouds can cause acid rain; The eruption may also be accompanied by lightning
possible danger: immediate danger to the life and property of nearby areas; There is also a threat to aircraft
appearance, change and extinction, volcanic cloud describes the change of color and shape in the process of
from top to bottom.
the author's imagination is really rich. He compares huoshaoyun to a lively horse, a fierce dog... He can also use some words about color to reflect the colorful characteristics of huoshaoyun. As I read, I seem to follow the author's writing to the scene and feel the author's love for nature. What a beautiful article
what a beautiful cloud! The author is enthusiastic (H ā n) Chang gives us a beautiful picture of the fire cloud sunset
in the first natural paragraph, parallelism is used, which not only shows the vivid sunset, but also describes people's happy mood. A word "burn" vividly describes the characteristics of fire cloud: "red, it seems that the sky is on fire." With the metaphor of "fire", how bright and bright it is
the text vividly describes the changes of color and shape in the process of huoshaoyun from top to bottom after dinner. The author is very careful to observe the things around, I also want to learn to observe the strange nature, to appreciate the beauty of the world
fire burns clouds_ In the evening, the fire clouds come up. The big wolf dog in the red glow turned into red sandalwood. The little white pig became golden, and the little white rabbit became yellow. The sun has gone to the west, the earth, the roof and the treetops are all bright. I raised my head to see the cloud burning with fire. It was as brilliant as Nezha's Jingkun circle. After a while, the light faded. In a twinkling of an eye, a big tiger appeared in the sky. The tiger was very fierce, and then ran forward. It seemed that he was chasing his prey. Running, the prey did not know where to go, and the tiger disappeared. Suddenly there are two dragons playing with colorful beads, just like the two dragons playing with pearls in fairy tales. They are flexible and play with each other and become fuzzy. Then came a girl, with a long pink yarn and ribbon, dancing beautifully. But after a while, her Kung Fu changed. It's a pity that she can't see fairies. The sky is like this and that, and my eyes can't cope with it. When I look at it, my eyes become blurred and I can't see anything clearly...
