Why does it sometimes snow while the sun rises? What is this phenomenon?

This is really just a natural phenomenon that occurs when the temperature is low, the humidity in the air is high, and the clouds are not large. Low temperature and high humidity are necessary conditions for snowfall, and the small range of clouds allows solar energy to pass through the gaps in the clouds, forming a scene of solar snow, which generally does not last long.

Snow while the sun is out is: Sun snow refers to a weather situation where it snows while the sun is out. It is known as solar snow.

It is a natural phenomenon that the sun rises and snow falls on a sunny day. The main reason for the formation of solar snow is the formation of snowfall due to the influence of cold air, and at the same time, the altostratus clouds are not enough to cover the sun, so the weather phenomenon occurs when the sun rises while it snows.

This is due to the fact that the cloud cover is not wide enough. And then the clouds keep drifting, and then it just snows, and then the sun comes out.

The formation of solar snow is similar to that of solar rain, the difference is only in the temperature level. Meteorological experts say. On the one hand, cold air affects the formation of snowfall; On the other hand, Altostratus clouds are not enough to cover the sun, so the sun rises while it snows, and the sun snow generally does not last long, especially when the weather turns.

It seems that you are from the south, and there have been "solar snow" in northern cities, especially in the northeast, but because snowfall is rare in the southern region, and people in many places have not even seen snow for decades, so the appearance of "solar snow" will be surprising.

"Solar snow" is a type of snowfall that occurs in short bursts. It usually occurs around 9-10 o'clock in the morning or around 15-16 o'clock in the afternoon. During these periods, when the clouds producing snowfall are not thick and do not cover a large area, sunlight may shine obliquely through the gaps in the clouds, so that the ground will see the simultaneous occurrence of sunlight and snow.

If you want to see the snow to the north of the Yellow River, it is best to go to the northeast or northwest, but it is not very easy to see the "sun snow", you need to be in a hurry, just like watching the sunrise, not every time you can see it.

As long as it is daytime, the sun is always "out", but local weather and other meteorological reasons will cause the sun to be invisible. Snow and rain out of the sun are normal weather changes, but compared to rain, snowfall generally covers a larger area, and snow out of the sun is less common.

The snowfall process is generally produced under the action of a strong cold air mass, for our country in winter, the cold death mass in Siberia and other places goes south, and meets the local air mass, because the density of the cold air mass is large, the gas cold sinks and the light one lifts, and the air mass with higher local temperature is lifted to a higher place with the temperature drops, the water vapor carried in the gas will condense into water droplets or ice crystals, and the water droplets fall is rainfall, and the ice crystals fall is snowfall and other processes.

However, the ice crystals can continue to combine with water vapor to develop and grow during the descent process, so the diameter of the snow flakes can reach one or two centimeters, and the surface tension of the water is not enough to sustain large raindrops, and the raindrops are also blown by the updraft when they fall, and the volume is even more difficult to maintain, and the largest diameter of the raindrops recorded by scientists is between centimeters and 1 centimeter. It is also because the cold air mass is mostly a large-scale air mass movement, so the cooling and snowfall weather usually covers a larger area, and the snowfall is accompanied by less sun, but it is not nothing.

To put it bluntly, rain or snowfall is caused by atmospheric flow within a certain range, and the clouds formed in the flowing atmosphere are thin and thick, high and low, dry and wet, and the permeability is different, so some places may be accompanied by the sun when snowfall. The sun is always there, the difference is that the snowfall days are generally cloudy, the power of the sun in winter is relatively low, the sun is difficult to disperse the clouds, there are clouds in the formation of rain or snowfall, and the distance of the snow floating in the air is also affected by the wind, in the edge of the rain and snow weather, there may be a weather phenomenon of the sun while snowing, and the sun at that time is generally not very strong, that is, you can see some.

Some time ago, snow in some places was accompanied by thunder and lightning, which is also a meteorological phenomenon caused by natural causes, but at that time, the atmospheric humidity was higher, the density was greater, and the friction with the ground could produce more electric charges, and the snow was also a more humid type.

There are many kinds of natural weather phenomena, and we generally only notice those that are more special, but they are nothing more than another change in the precipitation process, and there is nothing special about it.

Because the temperature is low and the air humidity reaches a certain requirement, it snows, which has nothing to do with the lack of sun.

This is a natural phenomenon, and the main reason for the formation of solar snow is the formation of snowfall due to the influence of cold air, and at the same time, the thickness and density of the cloud cover cannot block the sun, so there is a weather phenomenon of snow and sun at the same time.

Because the climate and environment have reached the conditions for snow, and the sun is not necessary for snow, it still snows when the sun is out.

As long as the temperature is below zero and there is enough moisture to condense into ice, it will snow when the sun comes out.
