Little knowledge about snowflakes

1. What is the knowledge about snow?

As we all know, pure water is colorless and transparent, so why are the falling snowflakes white? Transparency means the ability to transmit light.

The reason why water is colorless and transparent is that light of various colors can pass through it when the water is not deep. Snowflakes are mainly composed of small water droplets with a water film on the surface. The small water droplets are like small prisms; when light shines on the water droplets, they will be reflected and refracted on their surfaces.

The light refracted into the water droplets will hit the surface of the surrounding water droplets when it is emitted, and will be reflected and refracted again... Finally, after multiple refractions and reflections, the light is reflected from various directions.

And because the surface of water droplets has almost equal opportunities to reflect light of various colors, rather than selective reflection, the waves appear white under sunlight. Because the crystal structure of the ice that makes up the snow flakes is complex and has many reflective surfaces, it can fully reflect and refract the light. As a result, the snowflakes appear white in color.

2. It’s snowing, let’s popularize your knowledge. Do you know the different types of snowflakes?

The process of snowflake formation: When the condensation nuclei are below zero degrees Celsius, water points will begin to condense. into ice crystals.

Since those water droplets are very small and invisible, many people mistakenly think that this is sublimation. Sublimation is when water vapor turns directly into ice without passing through the liquid state.

When ice crystals form, the water points surrounding the ice crystals will solidify and stick to the ice crystals. The small ice crystals will attract more water points and gradually grow into larger ice crystals, until two to two hundred Ice crystals are connected together, and different and unique snowflakes are formed according to the atmospheric environment. Snow particles fall from the sky to the ground at different speeds. Very small crystals fall at a speed of almost zero. Generally, snowflakes fall at a speed of one meter per second, and melting snow is several times faster.

Whenever snow crystals encounter supercooled water points, they will immediately solidify together, and the soft particles formed are snow pellets, and the whole process is called "frost". In temperate areas, the increase in water molecules causes the growth of ice crystals, forming snowflakes.

Its ingenious hexagonal body has become the secret of the growth of snowflakes. Each snowflake has at least hundreds of millions of water molecules, and the ice crystals grow into larger and thicker crystals from the horizontal and vertical directions. However, the whole process has the characteristics of hexagonal symmetry, which is incredible.

3. Snow beer knowledge

The raw materials of snow beer are barley, brewing water, hops, yeast, starchy auxiliary raw materials (corn, rice, barley, wheat, etc.) and sugars Auxiliary raw materials, etc.

Barley The barley suitable for beer brewing is two-row or six-row barley. Two-row barley has a high leaching rate and good solubility; six-row barley has higher agricultural yields and strong vigor, but has a low leaching rate and unstable malt solubility.

The quality requirements of barley for beer are: low hull component, high starch content, moderate protein content (9~12%); light yellow and shiny; moisture content less than 13%; germination rate in More than 95%. Brewing Water Generally, soft water is suitable for brewing light beers, and hard water with a high carbonate content is suitable for brewing strong beers.

The water requirements for light beer are: colorless, odorless, transparent, no floating matter, pure taste, no biological pollution; low hardness; low iron and manganese content (high content is harmful to the color and taste of beer) , and can cause spewing); does not contain nitrite. Hops are also called hops.

It gives beer a unique bitter taste and aroma and has the ability to preserve and clarify wort. Hops were first used in Germany. Its scientific name is Lupus. It is a perennial creeping herbaceous plant of the family Cannabis and the Humulus genus. It is dioecious and the flowers used for brewing are all female.

China's artificial hop cultivation has a history of half a century, starting in the Northeast. Currently, large hop raw material bases have been established in Xinjiang, Gansu, Inner Mongolia, Heilongjiang, Liaoning and other places. Mature fresh hops are dry-pressed and used as whole hops, or crushed and pressed into particles and then sealed and packaged. They can also be made into hop extract and then stored in a low-temperature warehouse.

Its active ingredients are hop resin and hop oil. The amount of hops per Kl of beer is about 1.4~2.4kg.

Yeast Yeast is a microorganism used for beer fermentation. Beer yeast is divided into top-fermenting yeast and bottom-fermenting yeast.

In order to ensure the purity of yeast, beer factories conduct pure culture starting from single-cell culture methods. In order to avoid contamination by wild yeast and bacteria, the cleaning and sterilization work of the beer factory must be strict.

Corn Corn starch has roughly the same properties as barley starch. However, corn germ contains more oil, which affects the brewing properties and flavor of beer.

Removing the germ removes most of the corn oil. The fat content of degerminated corn should not exceed 1%.

Beer brewed with corn as auxiliary raw material has a mellow taste. Corn is the most commonly used auxiliary raw material in the world.

Rice has high starch content, high leaching rate, and low oil content. However, the gelatinization temperature of rice starch is higher than that of corn.

Beer brewed with rice as an auxiliary raw material has a light color and a refreshing taste. Rice is the most commonly used auxiliary raw material in China.

Sugar is mostly used in sugar-producing areas, and the general usage amount is 10~20% of the raw materials. The types added mainly include sucrose, glucose, invert sugar, syrup, etc.

Wheat: German white beer uses wheat malt as the main raw material, and Belgian lambic beer uses barley malt with wheat as auxiliary ingredients to brew top-fermented beer with local characteristics. Wheat varieties include hard wheat and soft wheat, and soft wheat is suitable for the beer industry.

Beer production Beer production can be roughly divided into three main processes: malt manufacturing, beer brewing, and beer filling. Malt manufacturing has the following 6 processes.

Barley storage: Freshly harvested barley has a dormant period and has low germination power, so it needs to be stored for post-ripening. Barley selection: use wind power and sieving machine to remove impurities, and sieve the wheat grains into first, second and third grades according to their size.

Soaking the barley: Soak the barley in water for 2 to 3 days in the barley soaking tank, and wash it at the same time to remove the floating wheat so that the moisture (soaking degree) of the barley reaches 42~48%. Germination: The water-soaked barley is germinated under temperature-controlled and ventilated conditions to form various substances that dissolve the contents of the wheat grains.

The suitable temperature for germination is 13~18℃, the germination cycle is 4~6 days, and the elongation of root buds is 1~1.5 times the length of the grain. The grown wet malt is called green malt.

Baking and drying: The purpose is to reduce moisture and stop the growth and decomposition of green malt for long-term storage; to make the malt form substances that give beer color, aroma and taste; to easily remove root buds, and after baking and drying The malt moisture content is 3~5%. Storage: The roasted malt is stored in concrete or metal silos after removal of wheat roots, selection, and cooling.

Beer brewing has the following five processes. There are mainly three processes: saccharification, fermentation, and wine storage and maturation.

Raw material crushing: The malt and rice are crushed separately by a crusher to a crushing degree suitable for the saccharification operation. Saccharification: Mix the crushed malt and starchy auxiliary materials with warm water in the gelatinization pot and the saccharification pot respectively, and adjust the temperature.

The mash pot is first maintained at a temperature (45~52°C) suitable for protein decomposition (protein resting). After the completely liquefied mash in the gelatinization pot is added to the saccharification pot, it is maintained at a temperature (62~70°C) suitable for saccharification (β-starch and α-starch) (saccharification is stopped) to produce wheat mash.

There are two ways to increase the temperature of wheat mash: leaching method and boiling method. The protein, saccharification rest time and temperature rise method are determined according to the nature of the beer, the raw materials used, equipment, etc. After filtering out the wort in a filter tank or filter, boil it in a boiling pot, add hops, and adjust to the appropriate wort concentration. Afterwards, it enters the gyratory sedimentation tank to separate the hot coagulated matter, and the clarified wort enters the cooler and is cooled to 5~8°C.

Fermentation: Add yeast to the cooled wort and send it to the fermentation tank or cylindrical conical bottom fermenter for fermentation. Use a coiled tube or jacket to cool and control the temperature. When carrying out the following fermentation, the maximum temperature is controlled at 8~13℃. The fermentation process is divided into foaming period, high foaming period and low foaming period. Generally, fermentation takes 5 to 10 days.

The fermented beer is called tender beer. It is bitter, rough in taste, has low CO content and is not suitable for drinking. Post-fermentation: In order to post-ripen the tender beer, send it to a wine storage tank or continue to cool it to about 0°C in a cylindrical cone-bottom fermentation tank. Adjust the pressure in the tank to dissolve CO into the beer.

The wine storage period takes 1 to 2 months. During this period, the remaining yeast, cold condensate, etc. gradually precipitate, the beer gradually becomes clear, CO is saturated in the wine, the taste is mellow, and it is suitable for drinking.

Filtration: In order to make the beer clear and transparent and become a commercial product, the beer is clarified and filtered at -1°C.

The requirements for filtration are: large filtration capacity, good quality, low loss of wine and CO, and no impact on the flavor of the wine. Filtration methods include diatomaceous earth filtration, cardboard filtration, microporous membrane filtration, etc.

4. Meteorological knowledge about snow

Snow is precipitation composed of a large number of white opaque ice crystals (snow crystals) and their polymers (snow masses).

On the earth, water is constantly circulating. Water in the ocean and on the ground is heated and evaporates into the sky. This water vapor moves to other places with the wind. When they encounter cold air, they form Precipitation returns to the Earth's surface. There are two types of precipitation: one is liquid precipitation, which is rain; the other is solid precipitation, which is snow or hail.

Most snow falls from nimbostratus clouds and altostratus clouds, and the precipitation intensity changes slowly. Snowfall in cumulonimbus clouds in cold weather has the characteristics of showers, which are called snow showers.

Snowfall is composed of a large number of snow crystals of different sizes, with generally more small ones. In order to describe the size distribution characteristics of snow crystal groups falling at the same time, the snow crystal spectrum or the solution spectrum after the snow crystals melt is commonly used.

Snow crystals mainly grow by sublimation in clouds. First, ice crystals are generated through the action of ice nuclei in cold clouds. They grow into snow crystals through sublimation (ice crystal process), and can later freeze. Grow up from supercooled water droplets. When the snow crystal hits a lot of frozen supercooled water droplets, its shape will change. Snow crystals have various shapes, which are related to the temperature and humidity of the environment in which they grow.

5. What are some common sense to pay attention to in winter climate?

Winter: Chinese custom refers to the three months from the beginning of winter to the beginning of spring, and also refers to the "10th, 11th, 12th, and 12th" of the lunar calendar. "One *** three months.

From a climatological perspective, winter is defined as when the average temperature is below 10°C for 5 consecutive days. 1. Why is the temperature difference between the north and south of my country large in winter? In the north, in winter, affected by the cold high pressure in Siberia, Mongolia, cold air often moves southward to form cold waves, which greatly reduces the temperature.

In the south, affected by warm and moist air currents from the ocean, winters are mostly mild. This is due to climate.

Mountains running east-west, such as the Qinling Mountains, block cold air masses from moving south, making the temperature in the south relatively high and the temperature in the north very low. The temperature difference is naturally large. This is due to the terrain.

Under the combined effect of multiple geographical factors (solar radiation, climate, terrain), the temperature difference between the north and south of my country is much larger in winter than in summer. 2. What are cold waves and cold snaps? When you watch the news, you may often hear the term "blue warning" for cold waves.

Cold wave is a kind of disastrous weather in winter. According to the regulations of the Meteorological Observatory, the cooling caused by the passage of cold air can drop by an average of 10℃ per day. When the minimum temperature is below 5℃, it is called a cold wave. The air is cold wave. People are accustomed to calling cold waves cold waves. In fact, this is wrong. Cold waves are different from cold waves. Cold waves are a type of ocean current. It refers to the large-scale flow of sea water from high latitude sea areas to low latitude sea areas in the ocean.

There are five famous cold currents in the world: the California Cold Current in the North Pacific, the Peruvian Cold Current in the South Pacific, the Canary Cold Current in the North Atlantic, the Benguela Cold Current in the South Atlantic, and the Western Australia Cold Current in the South Indian Ocean. They flow from high-latitude seas to low-latitude seas in the northern and southern hemispheres respectively.

3. The cold weather is not because we are far away from the sun. People always use the stove or heater after entering the house. Moreover, everyone knows that the closer you are to the stove or heater, the higher the temperature; the further away from the stove or heater, the lower the temperature.

The sun is also a big furnace. Sometimes the earth is closer to the sun and sometimes further away. Does it mean that the temperature is higher when it is closer to the sun and lower when it is farther away? The earth's orbit around the sun is elliptical, and the distance between the sun and the earth is constantly changing. Every January 3rd is the day when the sun and the earth are closest, and July 4th is the day when the sun and the earth are farthest away. Logically speaking, January should be hot and July cold, but the actual situation is exactly the opposite.

In fact, the earth is too far away from the sun. The average distance between the two is 150 million kilometers, while the distance between the sun and the earth at its farthest and closest is only 5 million kilometers. This distance has little impact on the earth's access to solar heat.

What really determines the heat and coldness on the earth is the angle of the sun. Because the Earth is tilted and rotates around the sun, the angle at which the sun shines on a certain location on the Earth will constantly change.

In summer, the sun shines directly on the northern hemisphere; in winter, the sun shines diagonally on the northern hemisphere. The same amount of sunlight hits a smaller area in direct rays than in slanted rays.

So in a place of the same size, when the sun shines directly, it receives more sunlight, and the weather is hot; when the sun shines obliquely, it receives less sunlight, and the weather is naturally cold. 4. Why does it snow? In winter, snowflakes often fall from the gray clouds and fall to the ground, revealing the world covered in silver.

So, why does it snow? Snow is a form of precipitation, which is called solid precipitation in meteorology. Snowflakes grow in a cloud that contains both ice crystals and supercooled water droplets. This type of cloud is called an ice-water mixed cloud.

In this kind of cloud body, supercooled water droplets continue to evaporate into water vapor, and the water vapor continuously flows to the surface of the ice crystals, where it condenses and settles, causing the ice crystals to gradually grow to form snowflakes. After the snowflakes form, they fall downward. During the falling process, when they encounter other snowflakes, they often stick together and slowly grow. When encountering updrafts, small snowflakes rise faster than large snowflakes, and small snowflakes catch up with them. The large snowflakes on the ground adhere to each other, and after repeated adhesion, they gradually become cotton-like and goose-feather-like snow masses with a diameter of several centimeters.

When the updraft in the air can no longer hold these snowflakes, they will fall down from the clouds. If the temperature of the low-level air is below 0℃ at this time, the snowflakes will fall to the ground. This is what people do The white snow you see. 5. Why are there so few thunders in winter? Thunder is a discharge phenomenon of positive and negative electricity produced by the violent collision of convective clouds.

my country’s winter is mainly controlled by northwest airflow, with low temperatures and few opportunities for convective clouds to form. In summer, when the temperature is high, the ground updrafts and high-altitude cold air currents form convective clouds. Electron clouds are easily generated during violent collisions. When the discharge distance is reached, discharges are generated, forming thunder and lightning, so there are more thunder and lightning.

In winter, due to the control of continental cold air masses, the air is cold and dry. In addition, the solar radiation is weak, and the air is not easy to form violent convection, so thunderstorms rarely occur. But sometimes the weather in winter is warm and the warm and humid air is strong. When strong cold air from the north occasionally moves southward, the warm and humid air is forced to rise, and convection intensifies, causing thundershowers, a phenomenon called "thunder winter".

Some experts say that the generation of thunderstorms does not depend on the temperature itself, but on the upper and lower distribution of temperature. In other words, although the temperature is not high in winter, if the temperature difference between the upper and lower reaches a certain value, strong convection can form and thunderstorms can occur.

Winter thunder is rare in China, but it often occurs in winter in Toronto, Canada. 6. The shape of snowflakes Some people think that the shape of snowflakes are all the same, that is, hexagonal. In fact, there are no snowflakes with the same shape in the world.

Some six-pointed star-shaped snowflakes are also called tree shapes, and they continue to condense water vapor as they fall or combine with other snowflakes to form large snowflakes. Moreover, when snowflakes fall, they will be affected by temperature, humidity, and wind and deform.

7. Why is it foggy in winter? When the air holds the maximum amount of water vapor, it is saturated. The higher the temperature, the more water vapor the air can hold.

When the temperature is 4°C, 1 cubic meter of air can hold up to 6.36 grams of water vapor; when the temperature is 20°C, the maximum amount of water vapor that can be contained in 1 cubic meter of air is 17.30 grams. . If the water vapor contained in the air is more than the saturated amount of water vapor at a certain temperature, the excess water vapor will condense out. When enough water vapor is combined with the tiny dust particles in the air, the water molecules themselves will also interact with each other. When bonded, they become small water droplets or ice crystals.

The water vapor in the air exceeds the saturation level and condenses into water droplets. This is mainly caused by the drop in temperature.

6. Little knowledge about rain

The basic process of rain formation is: water vapor in the air condenses into small water droplets or small ice crystals at high altitude. Small ice crystals collide and merge with each other, becoming larger and larger. When they are so big that the air cannot support them, they will fall. When the low-altitude temperature is higher than 0℃, it is rain.

Clouds composed of liquid water droplets (including supercooled water droplets) are called aquatic clouds. If the conditions for the cloud droplets to grow into raindrops are met in the water cloud, and the raindrops have a certain falling speed, what falls down will be rain or drizzle.

Clouds composed of ice crystals are called ice clouds, while clouds composed of water droplets (mainly supercooled water droplets) and ice crystals are called mixed clouds. Ice crystals or snowflakes falling from ice clouds or mixed clouds fall into the air layer above 0°C. After melting, they also become raindrops and fall to the ground, forming rainfall.

Large water droplets play an important role in the formation of rain. When the radius of a water droplet increases to 2-3mm, the gravitational force between water molecules is difficult to maintain such a large droplet. During the fall, it is easy to be impacted by the airflow and split through a "chain reaction".

Make the large water droplets fall, and the small water droplets continue to exist, forming new large water droplets. This is an important reason for the formation of rain in aquatic clouds and mixed clouds with strong updrafts.

7. Regarding the knowledge of snow, I will add 50 points, urgent.

Snowflakes are a kind of beautiful crystals that cling together in groups as they fall. It forms snow flakes. The size of individual snowflakes usually ranges from 0.05 to 4.6 mm. Snowflakes are very light, weighing only 0.2-0.5 grams each. No matter how light and small the snowflakes are, or how wonderful they are, their crystals are all regular hexagonal shapes. Therefore, the ancients said that "there are five flowers in the grass and six in the snowflakes." How beautiful and light the snowflakes are! I like snowflakes more and more. It would be a joy to see the snow-covered earth and the green trees covered with silver again.

"Auspicious snow heralds a good harvest" is a widely circulated agricultural proverb in my country. In the north, a thick and loose layer of snow is like covering wheat with a quilt to keep out the cold. The nitrogen trapped in the snow is easily absorbed and utilized by crops. The low temperature of snow water can freeze to death overwintering pests on the surface, which also brings benefits to agricultural production. Therefore, there is another farmer's proverb, "Three layers of wheat quilt are used in winter, and steamed buns are used as pillows to sleep next year."

Snow has a wide range of functions, but snow has great benefits for human beings. First, it is beneficial to the growth and development of crops. Because snow has poor thermal conductivity, covering the soil surface with a layer of snow can reduce the transfer of soil heat and block the intrusion of cold air on the snow surface. Therefore, crops protected by snow can survive the winter safely. Snow also stores moisture for crops. Additionally, snow enhances soil fertility. According to measurements, every liter of snow water contains approximately 7.5 grams of nitrogen compounds. Snow water seeping into the soil is equivalent to applying nitrogen fertilizer. Using snow water to feed livestock and poultry and irrigate crops can yield obvious benefits.

Snow is good and bad for people. In the mid-spring season of March and April, it snows heavily due to a sudden cold wave. It will cause freezing cold. Therefore, the farmer's proverb says: "Snow is a treasure, but spring snow is not good."

In winter, heavy snow falls in the vast sky. When people appreciate Yushu and Qionghua, they often ignore the role of snow. Snow has many benefits for human health. "Compendium of Materia Medica" has long recorded that snow water can detoxify and cure plague. Folks use snow water to treat fire burns and frostbite.

Regular bathing in snow water can not only enhance the resistance of the skin and body, reduce diseases, but also promote blood circulation and enhance physical fitness. If you drink clean snow water for a long time, it will help prolong your life. This is one of the "secrets" for those long-lived old people living in the deep mountains and forests to live long.

Why does snow have such strange functions? Because the amount of heavy water contained in snow water is 1/4 less than that in ordinary water. Heavy water can seriously inhibit biological life processes. Someone has done experiments and found that fish will die quickly in water containing 30 to 50% heavy water. The most basic condition for the formation of rain and snow is the existence of "condensation nuclei" in the atmosphere, and solid impurities such as dust, coal particles, and minerals in the atmosphere are the ideal condensation nuclei. If the water vapor, temperature and other meteorological factors in the air reach certain conditions, the water vapor will condense into snowflakes around these condensation nuclei. Therefore, snowflakes can clean a large amount of pollutants in the air. Therefore, the air seems particularly fresh after a heavy snowfall.

According to measurements, the density of new snow is generally 0.05~0.10 grams per cubic centimeter. Therefore, the reflectivity of snow on the ground to sound waves is extremely low, and it can absorb a large amount of sound waves and contribute to reducing noise.
