Why is it snowing now that it s snow grains and not snowflakes?

Because the snow particles fall before they "grow". ^_

The formation of snow is supposed to be related to many factors (I don't know exactly), I guess such as temperature, humidity, the number of particles in the air, and so on. To form a large enough snow particle that we can see as snowflakes, the requirements are only high, not low.

Maybe it's too high (low), or too low (high), or maybe it's because of air pollution that causes too much particulate matter. When there are more condensation nuclei, the snow becomes small and large, rather than large and small.

Originally, it was a snowflake, but due to the relatively high temperature, its corners were melted, forming this semi-liquid and semi-solid state!

Snow grains (also known as snow sand, snow seeds) are formed by the solidification of raindrops, and snowflakes are formed by the condensation of water vapor.

Because the air is polluted, the snow is not pure, so it's like a lump of...

Maybe it's too much snow, hehe.

It's a standing of dust in itself.

…Inexplicably, it's still a snowflake, are you and I illiterate.

The difference between snow particles and snowflakes is the formation process. Snow particles are formed by melting and then solidifying in the process of snow forming rocks and then landing, with snow first and then snow particles. Snow particles occur in winter, and the moist air flow in the air will instantly crystallize when it encounters a cold current, becoming snowflakes, and the snowflakes will become snow particles when the temperature at high altitude rises and the snow melts slightly.

Snowflake, also known as silver millet, jade dragon, jade dust, is a kind of crystal, is the water vapor in the sky through the condensation of solid precipitation, the structure changes with the change of temperature, mostly hexagonal, like flowers. There are so many shapes of snowflakes that each snowflake is an extremely delicate pattern that even many artists have admired.

Snowflakes are mostly hexagonal in shape, and this is because snowflakes belong to the hexagonal crystal system.

The Xiaoice crystals of snowflake embryos in the clouds are mainly of two shapes. A hexagonal form is long, long and thin, and it is called column crystal split jujube for sale, but sometimes its two ends are pointed, like a needle, called needle crystal. The other is in the form of hexagonal flakes, like the flakes cut from a hexagonal pencil, called flakes.

Summary. About the conditions under which snowflakes and snow particles are formed Why are there sometimes snowflakes and sometimes small snow particles, and how do they form?

Water vapor will condense when it encounters tiny particles, these small particles are called ice crystals, and the ice crystals slowly fall, and in this process, more water will condense on them, and they will slowly grow small branches and forks, so they will become the snowflakes we see, and if they don't encounter more water during the fall, they are just snow particles.

Thank you very much for your consultation, I hope I can help you, if you have any needs in the future, you can consult me, I will definitely answer patiently for you, I wish you a happy life.

It's all the same.

Snow particles are also snowflakes, but they are small, not visible with the naked eye, and must be placed under a microscope to see clearly, snowflakes are mostly hexagonal, and the reason why there are many patterns is because the ice molecules are hexagonal at most, for hexagonal flake ice crystals, because the curvature on the surface and the corner is the same, it has different saturated water vapor pressure.

The saturated water vapor pressure is the highest at the corner, followed by the upper edge, and the smallest on the plane. In the case of the same actual water vapor pressure, the condensation growth of ice crystals is different due to the different saturated water vapor pressures of each part. For example, when the actual water vapor pressure is only greater than the saturated water vapor pressure of the plane, the water vapor only condenses on the surface, forming a columnar snowflake base dispersion.

When the actual water vapor pressure is greater than the saturated water vapor pressure on the edge, condensation will occur on the edge and on the surface. Because the speed of condensation is also related to the curvature, the condensation is faster in places with large curvature, so the condensation on the edge of the ice crystal is faster than on the surface, and more flakes are formed. When the actual water vapor pressure is greater than the saturated water vapor pressure on the corner, although there are water vapor condensation on the surface, edge, and corner, the position at the sharp corner is prominent.

Water vapor ** is the most sufficient, and condensation grows the fastest, so it mostly forms dendritic or star-shaped snowflakes. In addition, the constant movement of ice crystals and the changing temperature and humidity conditions in which they are exposed to them can cause the various parts of the ice crystals to grow at different rates, resulting in a wide variety of snowflakes.

Snow particles are Xiaoice hail.

There are various forms of air movement in the atmosphere, forming different forms of clouds. Clouds formed by convective movements include Cumulus palliensis, Cucumulus congestus, and Cumulonimbus clouds. They are collectively known as cumuliform clouds.

They are all isolated patches of clouds that develop upwards in isolation, because there are ascending and sinking motions in the convective movement, often forming cloud patches in the updraft region, and in the downdraft region it becomes a gap between the clouds, and sometimes blue sky is visible.

When the water on the surface is exposed to the sun and vaporized, and then rises into the air, a lot of water vapor comes together and condenses into clouds, at this time the relative humidity is 100%, and when it encounters cold air, it liquefies, and the dust in the air is the condensation nucleus.

Raindrops (tropical rain) or ice crystals (mid-latitude rain) are formed, which are getting bigger and bigger, and when the temperature drops to a certain level, the air is saturated with water vapor, so it rains, and if it encounters cold air without condensation nuclei, the water vapor condenses into ice or snow, which is snow, and if the temperature drops sharply, it forms a large ice mass.
