This is a cotton wool cloud. It appears in the summer morning that the air stratification is unstable, and it is prone to thunderstorms in the afternoon. So, the answer is yes. It ’s just not so easy.
Cloud is the phenomenon that water vapor in the atmosphere condenses into water droplets or sublimates into ice crystals suspended in the air. These small water droplets or ice crystals are getting bigger and bigger, and the air buoyancy can not support falling to the ground, which is the phenomenon of rain or snow that we have seen.
What kind of cloud will bring what kind of weather. Of course, to identify what type of clouds these clouds are, it will rain, and what kind of clouds will be rained, is a comprehensive result of various natural environmental factors: temperature, humidity, atmospheric stability, time and season, etc. Etc., so you ca n’t just judge by the shape of the cloud. None of these can be mastered in a day or two, which requires a relatively long time to accumulate, so this is a high-level field survival skill.
For thousands of years, our working people have accumulated rich practical experience through daily countless observations in daily life, so that people can gradually dispel the mysterious veil of nature, gradually recognize the original face of nature, and have become aware of many natural phenomena. Preliminary understanding. Most of these perceptual knowledges are passed down in the form of meteorological proverbs. In the process of proverbs, on the one hand, due to natural elimination, reasonable and correct proverbs can be intermittently spread, and those one-sided and incorrect proverbs are gradually eliminated; On the other hand, as time passes, people's understanding of nature is further deepened, so new content is gradually added. These meteorological proverbs have been handed down to this day in countless elimination and replenishment processes. This is why we can use these proverbs and experiences to judge the reason for the weather changes.
To master these ancient proverbs and correctly judge the weather changes, this is not an easy task, you need to do the following:
1. Know every cloud in the sky
2. Know the reasons and characteristics of each cloud formation
3. Be aware of the development and changes of the cloud in front of you
4. Understand what types of clouds these meteorological proverbs refer to
5. Refer to other environmental factors
1. Know the clouds in the sky
To put it simply, there are three main forms of clouds: cumulus clouds, large layers of stratus clouds, and cirrus clouds. The combination of these forms, plus the height, all clouds are divided into 10 families: Stratus, Rain Stratus, Stratus Cumulus, Cumulus, Cumulonimbus, Tall Cloud, Altocumulus, Cirrus, Cirrus, Cirrocumulus. These clouds can't escape these words: layer, volume, rain, height, volume. The so-called "accumulation" is a clump; the so-called "layer" is a large piece; the so-called "volume" is a thread; the "high" refers to the relative height of the cloud in the sky.
Stratus: a large cloud Cumulus: clouds of clouds Cirrus: a cloud of clouds So the characteristics of these families are already obvious:
Stratus: a large area;
Rain cloud: a thick, dark and rainy patch;
Cumulus: a bunch of clouds;
Cumulonimbus: a thick, dark, rainy mass;
High-level cloud: high and large;
Altocumulus: a piece of height;
Cirrus clouds, filamentous;
Cirrostratus: a large piece of silk;
Cirrocumulus clouds, lumps of filaments.
Although there are observed morphological features, this is not enough to clarify the type of cloud, which requires another indicator for classification: height. According to different heights, people divide 10 cloud genera into three cloud families: those with the word "juan" into the high cloud group; those with "high" into the middle cloud group; others into the low cloud group. Some people also categorized cumulus and cumulonimbus as the fourth cloud group: Zhizhan cloud group. But this does not matter, and does not affect our judgment of the weather.
In this way, the classification of clouds is relatively clear: under the three major cloud groups, there are 10 cloud genus, and under 10 cloud genus, there are various types of clouds. China's classification method refers to international standards, and there are 29 cloud types. So there are not many types of clouds in the sky. There are 29 in total. Observing carefully, it is not difficult to remember.
2. The causes and characteristics of various clouds
The causes of cloud formation are complex, but nothing more than the following: convection, disturbance, forced ascent, radiative cooling, and frontal effects. The ever-changing clouds in the sky are all produced by the combined effect of these factors. Each type of dynamic factor has its own characteristics. For example, the frontal effect generally forms a stratified cloud; the convective effect generally generates a cumulus cloud; the disturbance generates a wavy cloud and so on.
Pod-shaped cloud: a strange cloud created by the air being forced to rise due to the high mountain on the left 3. Clearly understand the development phase of the cloud
Clouds will not be created out of thin air, nor will they dissipate for no reason. There are certain rules to follow for their development and changes. For example, the development and changes of cumulus clouds are generally broken cumulus clouds-pale cumulus clouds-dense cumulus clouds-cumulonimbus clouds. You can understand what stage of development the cloud is in front of you in order to distinguish what kind of changes it will produce. For example, cumulus has reached the stage of cumulonimbus, there is more than 80% probability of thunder and rain, cumulonimbus cloud top I saw a pseudo-cirrus cloud, which is already in the dissipation stage. Even if it rains, the cloud will soon stop raining.
Hook Cirrus: A large area invaded from a certain sky, indicating that there is a stronger front behind moving to the local area, and the weather will deteriorate in a day or two 4. What type of cloud are these meteorological proverbs referring to?
People in ancient times were limited to the social conditions and knowledge of the natural world at that time, but also restricted to inconvenient transportation, and the living environment in which people lived was relatively small, so every weather proverb has its strong locality, one-sidedness and seasonal . If these proverbs use the wrong time and season, place and type, it is likely to produce the opposite result. Therefore, it is necessary to find out when these proverbs refer to, what type of cloud appears.
The so-called "the morning glow does not go out, the evening glow travels thousands of miles" refers to this kind of reflection This transmissive haze is not suitable for the above weather saying 5. Other environmental factors should be consulted:
Whether it is sunny or raining is not entirely determined by the clouds in the sky, but also depends on many other factors, such as atmospheric stability. If the atmosphere is stable, one of the generated clouds may not be able to develop to the stage of rain and will dissipate. If the atmospheric stability is low and the conditions are available, the cloud that may represent fine weather will quickly evolve into a precipitation cloud. .
When you have mastered the above know-how, coupled with long-term observation and accumulation, you can master the magical and practical skill of seeing the weather. "In the morning, the cloud blocks the dam, and it will go down if it is not overcast." In the summer morning, if you see thick cumulus clouds blocking the sun, don't dry the quilt! "The dark clouds catch the sun and you don't have to worry about rain in the middle of the night." When you see the sun falling from the thick cumulus clouds at night, don't wave outside. Hurry home and wash and sleep.
