Straight to the cloud family

Straight clouds have very strong updrafts, so they can grow all the way from the bottom to the higher. Pen~fun~Ge www.biquge.info Cumulonimbus clouds with a lot of rain and thunderstorms can start from a height close to the ground and then develop all the way to an altitude of 75,000 feet. At the base of the Cumulonimbus cloud, milky clouds that resemble pouches form when the cooler air in the descent meets the warmer air in the rise. Thin clouds form at the top of the Cumulonimbus when they expand.

●Cumulus clouds (cumulus)

Vertically upward, with an arc or arch overlapping convex top, and an almost horizontal cloud mass at the bottom. The clouds are well bounded. If the Cumulus and the Sun are in opposite positions, the middle of the cloud is brighter than the edge of the uplift; Conversely, if on the same side, the middle of the cloud appears dark but the edges are distinctly golden; If the light shines on the cumulus clouds from the side, the light and darkness of the clouds are particularly noticeable. Cumulus clouds are formed by the rise of air masses and the condensation of water vapor. Cumulus clouds can be further divided into 3 categories:

1Cuhum: Flattened cumulus clouds, not flourishing vertically, with a horizontal width greater than the vertical thickness. It is white in sunlight, with a faint shadow in the middle of thick clouds, and is common on sunny days.

2 Fragmentation Cumulus (FC): Fragmented irregular Cumulus clouds (patches), small individuals, variable shapes.

3Cucong: a thick cucumulus cloud with overlapping arc-shaped convex tops, much like cauliflower; When the vertical development is vigorous, the specimen is bloated, towering, and white and bright at the edge in sunlight. Occasionally, showers of precipitation can occur.

●Cumulonimbus (CB) is a thick and large cloud with extremely vertical development, which looks like a towering mountain from a distance. Cloud tops are made up of ice crystals with a white hair-like lustrous silk structure, often anvil-like or horsehair-like. The base of the cloud is dark and chaotic, with obvious undulations, sometimes in a hanging bulb structure. Cumulonimbus clouds often produce thunderstorms, showers (snow), or drooping rain (snow). Sometimes squall or hail falls. Occasional tornadoes occur at the base of clouds. Cumulonimbus clouds also have their own kind, Nimbostratus. The difference between the two is that the cumulonimbus cloud rains for a short time, but it is very violent; Nimbostratus lasts for a long time, but it does not fall as violently as Cumulonimbus.

Cumulonimbus clouds can be further divided into 2 categories:

1 Cumulonimbus baldis (CBCALV): The transition stage from Cumulus dense to Cumulonimbus capillus, the cauliflower-shaped outline gradually becomes blurred, and the top begins to freeze, forming a white hair-like ice crystal structure. Cumulonimbus baldis clouds generally exist for a relatively short period of time.

2-Capped Cumulonimbus: The mature stage of the development of Cumulonimbus clouds, the cloud top has a distinct white hair-like ice crystal structure, mostly horsehair or anvil-shaped.

Contrails are elongated, thin clouds that form when jetjets streak across the sky.

Noctilucent clouds are very rare, they form in the middle layer of the atmosphere and can only be seen at high latitudes.

Long-term observation and practice have shown that the generation and dissipation of clouds, as well as the evolution and transformation between various types of clouds, are carried out under certain conditions of water vapor and atmospheric movement. People can't see water vapor and can't see atmospheric movements, but they can see every move of water vapor and atmospheric movement from the evolution of clouds, and water vapor and atmospheric movement play an extremely important role in weather phenomena such as rain, snow, ice, and hail.

For thousands of years, in the production practice, the working people of China have summed up a wealth of experience in "seeing the clouds and knowing the weather" according to the changes in the shape, direction, speed, thickness and color of the clouds, and compiled these experiences into proverbs. We have put together these proverbs about "looking at the clouds and knowing the weather" here, and those who are interested may wish to pay attention to some observations and comparisons.

"Hooked clouds in the sky, rain on the ground": Hooked clouds refer to cirrus fishing, behind which there are often fronts (especially warm fronts), low pressure or low pressure troughs, indicating that rain is coming;

"Fort clouds, rain": Fort clouds refer to Fort Altocumulus or Fort Stratocumulus clouds, which mostly appear in front of low-pressure troughs, indicating that the air is unstable, and thunderstorms generally fall every 8-10 hours or so.

"Cloud-to-cloud, rain-drenched": Cloud-to-cloud refers to the inconsistency of the direction of movement of the upper and lower clouds, that is to say, the wind direction of the height of the cloud is inconsistent, often occurring near the front or low pressure, so it indicates that there is rain, and sometimes the cloud is opposite to the ground wind direction, then there is a saying that "against the wind and the clouds, the sky will change".

"The river pig crosses the river, and the heavy rain is pouring": The river pig refers to the broken rain cloud under the Nimbostratus cloud, and the appearance of this cloud indicates that the water vapor in the Nimbostratus is very sufficient, and the heavy rain is coming. Sometimes the broken rain clouds are blown by strong winds to a cloudless place, and at night, you can see clouds like river pigs drifting over the "Milky Way", which is also a sign of rain.

"Cotton clouds, rain is coming": Cotton clouds refer to flocculent Altocumulus clouds, the appearance of which indicates that the middle atmosphere is very unstable, and if there is sufficient water vapor in the air and there is an upward movement, cumulonimbus clouds will be formed, and thunderstorms will come.

"The gray cloth hangs in the sky, and the rain is continuous": the gray cloth cloud refers to the Nimbostratus cloud, which is mostly formed by the lowering and thickening of the high-level clouds, the range is very large, very thick, the water vapor in the cloud is sufficient, and continuous precipitation is often produced.

"The clouds go east, the carriages and horses pass; The clouds go south, and the water rises to the pool; The clouds go west, clothed in robes; Clouds to the north, good to dry wheat": according to the direction of the cloud's movement to predict cloudy and sunny, the cloud moves to the east and north, indicating that the weather is fine; The clouds move west and south, signaling that rain is coming. The direction in which the cloud is moving, generally indicates the direction of the wind at the height at which it is located. This proverb illustrates the distribution of clouds in different parts of the low pressure. It's suitable for dense all-day, low, fast-moving clouds.

"Ichthy scales, no rain and wind": Ichthy scales refer to cirrocumulus clouds, the appearance of this kind of cloud indicates that the upper atmosphere is unstable, if the clouds continue to lower and thicken, it means that the area is already in front of a trough of low pressure, and it will soon rain or wind.

"Carp spotted in the sky, tomorrow the valley does not need to be turned": carp spotted refers to translucent Altocumulus clouds, which are often under the control of denatured high-pressure air masses that are warmed by cold, and if the clouds do not continue to thicken, they will still be sunny in the short term. -------introduction

The wind was a little touched. From Yin Shan's trembling body, she knew that she was very scared and panicked in her heart, but she didn't run away. If she escaped with the help of the "Star God Praise Father's Power", I believe that Elder Yun would not be able to catch up at all. Worried and afraid, but never abandoned.

"This stupid girl is really kind-hearted." The wind said secretly in his heart, and at the same time, the domineering twisting tornado heart method was quietly transported in the dantian, and a strong aura dissipated......

The wind was protected by Yin Shan, what was the wind doing, Elder Yun couldn't see it at all, he just felt a strong breath, and his heart was shocked, but he didn't take it to heart, the wind was just a waste in his eyes, even if the wind could defeat the track cloud life form in one move, but he was not a track cloud life body, and he would not give the wind any chance to make a move.

"Little beauty, I'm here......" Elder Yun smiled evilly, and the steel broadsword swept up, this knife was not in Yin Shan, but in the wind behind her. He has always been meticulous in his work, he will not leave any hidden dangers for himself, first solve the wind, and snatch all the inheritance in the wind body, this is his goal, as for other things, you can take your time......

"Ah......h......h

Yin Shan squatted down suddenly, Elder Yun laughed wildly, the sword qi inspired by the qigong on the blade was very powerful, and he was about to cut off the head of the wind with one sword, but suddenly found that the wind was gone! Astound.

Suddenly, my mind was in turmoil, and fear arose inexplicably.

"Bump, bump, bump......" three punches in a row, and the wind poured out, hitting Elder Yunda's back. Gorgeous sneak attack, timing grasp, calculation, almost perfect. Elder Yun received three punches on his back, his face turned pale instantly, not because of pain, but because of the speed of the wind, looking at the appearance of the wind and the dragon, he said angrily: "Aren't you seriously injured?" Are your legs ,,, have you been pretending? ”

"Can't think of it, right?" Feng smiled and patted the thigh that was bitten by the little track cloud lifeform, the black blood on the thigh still kept gushing out, the whole leg was full of blood, and the ground flowed, "The blood of the track cloud, don't you see it?" "Just now, when the wind was harvesting the head of the tracking cloud, he deliberately accumulated some blood from the tracking cloud, and even Yin Shan didn't notice all this, how could the great elder Yun who was hiding in the cloud find out?
