Proverbs of Oriental Rainbow Sun and Western Rainbow Rain

Proverbs of Oriental Rainbow Sun and Western Rainbow Rain

I believe everyone is familiar with proverbs, and we have encountered many proverbs in our daily life. Proverbs are similar to idioms, but they are colloquial and easy to understand, and almost all of them are one or two short sentences. Let's share the proverb that the east rainbow sun and the west rainbow rain.

East red sun and west red rain proverb 1 East red sun and west red rain, which means: the rainbow is in the east, and there will be sunny days in the local area; The rainbow is in the west, where it will be rainy.

When the atmosphere is very dry, rainbows don't appear. Only when there are many small water droplets in the atmosphere, the sunlight is reflected and refracted by these small water droplets, and rainbows will appear in the sky.

The rainbow is in the east, indicating that there is rain in the eastern atmosphere, and the atmosphere generally runs regularly from west to east, and the bad weather in the east will only get farther and farther. If the rainbow is in the west, it means there is rain in the atmosphere in the west. With the operation of the atmosphere, rain will easily fall to this place.

Proverbs about the weather

1. It will be sunny when it rains in the morning, and it will rain until dawn at night.

It means that if it rains in the morning, it won't last long, but it will definitely be sunny during the day; But it's just the opposite when it rains at night. It usually rains all night.

2. The ants are moving the snake aisle, and the heavy rain will come soon.

It means that when you see swarms of ants moving on the road in broad daylight and snakes wandering on the road, it may rain soon, because animals have an innate nature.

3. There are clouds hanging in the sky and dripping water underground.

It means that if you see a hook cloud in the sky, it will rain these two days. The appearance of hook clouds indicates that a front or low pressure is coming, which is a sign before rain.

4, spring east wind, rain gurgling.

The east wind blowing in spring is a precursor to bad weather. This is because, on the one hand, the ground will get warmer in spring. On the other hand, the warm air becomes more active, the pressure on the mainland gradually decreases, the anticyclone moves eastward into the sea, and the easterly wind will appear at the tail of the anticyclone. These easterly winds flow to warmer land, leading to the phenomenon that the upper part is warm and the lower part is cold. At this time, the air layer is unstable and prone to upward convection, so it is very likely to produce precipitation.

East Rainbow Sun West Rainbow Rain Proverb 2 Agricultural Proverb "East Rainbow Sun West Rainbow Rain", rural people see the weather not only by animals!

Agricultural proverbs are mostly evolved from rural old sayings, whether about meteorology, farming or other aspects. These rural old sayings are the summary of the life experience of several generations of rural elderly. Although some words look simple, but carefully scrutinize, every sentence has a scientific basis in it. We should know that there was no weather forecast and wireless broadcast in the countryside before, whether to take an umbrella when going out tomorrow, and what crops to plant in the fields next year all depend on the "prediction" of agricultural proverbs.

Although with the constant change of the earth's environment, the precursors of different natural weather are also changing, and some ancient agricultural proverbs are slightly deviated, but in fact, most of them are very clever!

For example, "the stars are thin and the sky is clear." The combination of water vapor and dust in the sky will reflect light. "Sparse stars" means that there is less water vapor and dust in the sky, which is the main component of rain clouds. Without them, it is unlikely to rain the next day, so it is a good weather.

Another example is "the sun in the east rainbow and the rain in the west rainbow", and the scientific basis is also the change of light in physics. Rainbow is formed by sunlight turning into small water droplets in the air. Different colors of light are constantly diverging at different angles, and where the rainbow appears means which side is going to rain.

The place where rainbows appear is generally in contrast to the sun. "East rainbow" is "sunset rainbow" and "West rainbow" is "morning rainbow". However, the weather changes in temperate zone always occur in the west and then spread to the east, so this leads to the appearance of "East Rainbow", which will not rain immediately, while the appearance of "West Rainbow" means that heavy rain is coming.

Finally, I will introduce an animal, "It rains when the chicken enters the cage". The principle of this sentence is actually very simple. Before the rain, the air humidity was high, which caused many insects to fly low, and chickens would go back to their nests very late in order to eat more insects.

In rural areas, there are countless agricultural proverbs like this, all of which are the crystallization of the wisdom of predecessors. If you also want to predict the weather? Might as well learn more!

East Red Sun Xihong Rain Rumor 3 "East Red Sun Xihong Rain" _ Decryption of Meteorological Diary

It is observed that the noctilucent clouds in the northern hemisphere and the southern hemisphere are very different. The appearance of the rainbow "east rainbow sunny west rainbow rain" is closely related to the future local weather changes. The weather proverb "It's sunny in the east and rainy in the west" summed up by the working people in China is scientific.

"East Red Sunrises" means that when a rainbow appears in the east in the evening, it indicates that it will be sunny the next day, because East Red means that although there are many water drops in the air in the east and the humidity is very high, the rain area will continue to develop eastward without passing through the local area, so it won't rain there.

How are noctilucent clouds formed?

Mysterious noctilucent clouds

Noctilucent cloud is a rare cloud cluster, and it is one of the meteorological phenomena that the scientific community knows the least so far. It usually only appears in cold high latitudes. However, in recent years, noctilucent clouds appear more and more in low latitudes and become brighter and more frequent. When the sun is 30 ~ 60 minutes after sunset, that is, when the sun is 6 ~ 16 degrees below the horizon and facing the west, if you see white and blue wavy noctilucent clouds in the sky, you are likely to see rare noctilucent clouds.

Noctilucent clouds are also called polar mesospheric clouds. When they are seen from space, they are called "night clouds". Seen from the earth, it is called "noctilucent cloud". It is a cloud formed in the middle layer, about 85 kilometers above the ground, and its position is very high. This rare cloud can only be seen in summer at high latitudes of 50 ~ 70 degrees.

The noctilucent cloud looks a bit like cirrus cloud, but it is much thinner, and its color is bright silvery white or blue, which appears when the angle between the sun and the horizon is between 6 ~ 16 degrees after sunset. There is no doubt about this angle itself, because the noctilucent cloud is too weak to be seen too early and will sink into the shadow of the earth too late.

Moonlight clouds observed by humans

1885, humans first noticed this special cloud that can glow in the dark. In recent years, noctilucent clouds have appeared more frequently. Jim Russell, an atmospheric physicist at Hampton University in Virginia, said that compared with the past, noctilucent clouds appeared more frequently, for a longer time and at a lower latitude ... What is noctilucent clouds?

It is definitely not an ordinary cloud, because ordinary clouds never fly over the troposphere or stratosphere, but stay in the thin middle layer of the air. It's not like unpredictable aurora, because noctilucent clouds have cloud texture ... such clouds are absolutely unusual.

The mystery of the formation of noctilucent clouds

Some people think they are volcanic eruptions or groups of atmospheric dust, because only they can fly that high. Michael Stevens, a scientist at the US Naval Research Laboratory, believes that noctilucent clouds may be related to rocket smoke generated by the space shuttle engine.

At present, the most mainstream theory holds that noctilucent clouds are composed of extremely fine ice crystals. The ice crystals that make up the noctilucent cloud are generally 50 nanometers in diameter, and sunlight is reflected on these particles, so they can only be seen at dawn or dusk when the rest of the sky is dark. This effect is like watching an airplane flying high in the sky reflect sunlight after the sun sets.

It is generally believed that the formation of noctilucent clouds requires three conditions: low temperature, water vapor and dust, so that water vapor can condense into tiny ice crystals. In recent years, the noctilucent cloud can be seen when it spreads to the latitude of 40 degrees, and it appears more and more times and becomes brighter and brighter. This has aroused the strong concern of scientists, and some people worry that this is a precursor to the change of the earth's atmosphere.

It is observed that the noctilucent clouds in the northern hemisphere and the southern hemisphere are very different. The noctilucent clouds over the northern hemisphere look brighter than those over the southern hemisphere and appear at lower latitudes. In the northern hemisphere, there are often noctilucent clouds from May 15 to August 20, and the most frequent is early July. Cora Randall of the University of Colorado said that more and more greenhouse gases, such as carbon dioxide, have warmed the climate in low altitude areas and lowered the temperature in high altitude areas, thus creating conditions for the formation of noctilucent clouds in high altitude areas.

In addition, the high content of greenhouse gases will actually lead to the formation of more water vapor at high altitude. Randall said that low temperature and more water vapor are the reasons why most noctilucent clouds appear more frequently. This shows that the earth's atmosphere is changing.

Unveil the mystery of luminous clouds

On April 25, 2007, NASA launched the "Middle Atmosphere Ice Detection" satellite, trying to explore the mysterious noctilucent cloud lurking above the high latitude of the earth.

This is the first time that human beings have devoted themselves to the study of space noctilucent clouds. The "middle atmosphere ice detection" satellite finally entered the polar orbit about 600 kilometers above the earth. This satellite is equipped with three sets of scientific instruments. In the next two years, we will observe the mysterious noctilucent clouds at the poles of the earth to explain how noctilucent clouds are formed, why their frequency has increased in recent years, why their latitude is decreasing, and whether their appearance is related to climate change.

The Mystery of Beautiful Rainbow

The History of Rainbow Research

In summer and autumn, after a heavy rain, a magnificent and colorful Changhong often appears in the sky. It is like a splendid semi-arch colored bridge, flying above the horizon, forming a magnificent illusion in the air, attracting people.

In ancient times, many myths and legends appeared because people didn't understand the reasons for the formation of rainbows. Some people say that "the rainbow is a bridge crossed by the gods in the sky of Tianhe", some people say that "the rainbow is God's wand and whip", Arabs say that "the rainbow is a bow that the light god Gushahe puts on the clouds at rest", some people say that "the rainbow is the smile of the goddess of joy" and "Chang 'e's long sleeves are waved in the moon palace".

1624, Italian scholar Bishop Minnis explained the formation of rainbow with the principles of natural science. However, due to the backwardness and ignorance of the society at that time, the fatuous Pope excommunicated Bishop Minnis, sentenced him to death, and burned his works with his body.

Later, Descartes, a French scientist, saw an artificial rainbow with many water drops in the air by the pool. He did an experiment with a glass ball filled with water, and published an article on rainbow formation in 1637.

He said in the article: "Rainbow is the result of sunlight reflecting and refracting into water droplets in the air." But he still doesn't know how the color of the rainbow is formed. It was not until the 65438+60s that Newton discovered the dispersion phenomenon of sunlight passing through the prism that the secret of the rainbow was uncovered.

What is a rainbow?

Rainbow is a natural weather phenomenon. In the early summer and autumn, before and after the rain, when there are many small water droplets floating in the air, when the sun shines on these small water droplets, the original direction of sunlight is changed due to refraction, and the white sunlight synthesized by seven colors is scattered, making it become seven colors again;

Then through the reflection of the ground, a beautiful and bright arc of light is formed from the outside to the inside, which is arranged in the order of red, orange, yellow, green, cyan, blue and purple. This is the rainbow. The color and width of the rainbow are related to the size of water droplets. The bigger the water drops in the air, the brighter the color of the rainbow and the wider the ribbon. The smaller the water drop, the darker the rainbow and the narrower the ribbon.

"Rainbow in the East, Rainbow Rain in the Sun and the West"

The appearance of rainbow is closely related to the local weather changes in the future. The weather proverb "The sun shines in the east and the rain falls in the west" summarized by the working people in our country is scientific. In the temperate zone where we live, the upper air flow moves regularly from west to east. Therefore, the change of weather in the future is closely related to the nature of airflow in the west.

"East Red Sunrises" means that when a rainbow appears in the east in the evening, it indicates that it will be sunny the next day, because East Red means that although there are many water drops in the air in the east and the humidity is very high, the rain area will continue to develop eastward without passing through the local area, so it won't rain there. The corresponding dry air from the west will move to the local area, so it will be sunny the next day. "Rain on the rainbow in the west" means that a rainbow appeared in the west in the morning and it is going to rain soon.

Because there are a lot of water droplets in the western sky, these water droplets will develop eastward and move to this area. In addition, with the rising of the local sun, evaporation intensifies, and the water vapor at low altitude rises to high altitude and meets the water droplets at high altitude, which makes the water droplets at high altitude expand and increase, which is easy to cause rainy weather.

"When spiders hang their nets for a long time, it will clear up."

In many parts of our country, if you see spiders stretching their webs, the rainy weather will clear up; If the spider closes the net, it will become rainy.

Spiders can predict the weather mainly because they are very sensitive to the humidity changes in the air. There are many small spinnerets on the spider's tail, which are sticky and cold. When rainy weather comes, due to the high humidity in the air and a lot of water vapor, the water vapor is easy to condense into small drops in the spinneret, and the spider finds it difficult to spin silk, so it stops spinning and closes the net.

On the contrary, when the humidity in the air decreases and the weather improves, spiders spin silk smoothly and then set nets to catch insects. According to another study, spiders' legs can sense sounds with a frequency of 20-50 Hz. When the weather turns fine, insects are easy to move, and the buzz from flying will soon be discovered by spiders, so they add screens to prepare to catch them. This is why people observe the weather with the proverb "spiders hang on the net for a long time, after the rain clears".
