Why does it snow when there is sun?

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.

The clouds in the sky condensed and froze into snow and fell, and the sky was naturally clear when the clouds covered the sun.

In fact, as long as it is daytime, there must be the sun, and we can't see the sun because it is obscured by the clouds in the sky, and the sun can't see the ground.

When the outside temperature, water vapor saturation, and condensation nuclei reach the conditions for the formation of snow, it will snow, regardless of whether the sun appears or not.

Three necessary conditions are required for the formation of snow: temperature, water vapor saturation and condensation nuclei, and as long as the three conditions are met, the snow requirements can be satisfied.

1. When there is a sun in the sky, it is a normal natural phenomenon that the outside temperature is below zero in winter, because in winter in China, the sun shines near the Tropic of Capricorn, and the sunshine time in China is short, the temperature is low, and it is often below zero (the crystallization temperature of water) in winter.

2. Affected by the region, wind direction, that is, other special reasons, the relative humidity in the air may be very large at a certain height within a certain time, so that the water vapor saturation in the air will be very high, and ice crystals are more likely to be produced than water droplets in a high-altitude and low-temperature environment.

3. Condensation nuclei in the air are very small solid particles suspended in the air, which are related to local environmental factors.

From the above analysis, there is a high probability of snow in the sun, because the appearance of the sun is not the main direct factor in the formation of snow, as long as the influence of the sun on temperature has a certain limit, snow can be formed.

01 When strong cold air passes over warm water, dry cold air and warm and moist air meet to form snowfall, and at the same time, Altostratus does not cover enough to cover the sun, so that sunlight may shine obliquely through the gaps in the clouds, so that the ground will see sunlight and snow at the same time.

Solar snow is a unique weather phenomenon called cold current snowfall, which is the result of the local convergence of cold and warm air masses.

When strong cold air passes over warm water, cold dry air and warm moist air meet to form snowfall, and at the same time, Altostratus does not cover enough to cover the sun, so that sunlight may shine obliquely through the gaps in the clouds, so that the ground will see sunlight and snow at the same time. Put simply, when the cloud cover is not very large, the temperature is low, and there is enough moisture in the air, solar snow may occur.

In general, solar snow lasts for a short period of time and has little snowfall, which is a localized short-term snowfall and has no special meteorological significance. It has also been discovered that the snowflakes of the sun's snow sometimes seem to fall from the sky instead of falling from the sky, but from the bottom to the top. This phenomenon occurs because the snowflakes are drier, lighter, and more windy, creating the illusion that the snowflakes are floating from the bottom to the top.

Some sun rain is caused by dark clouds in the distance, and it is blown to another place by strong winds. Some of them are formed because two clouds with different charges collide with each other under the action of the solar wind, resulting in excessive water vapor content in the air in some areas. There is also a sudden change in the weather, it starts to rain, and the clouds have disappeared before the rain that falls from the sky has landed, so the weather looks clear, but it is raining.

Solar snow refers to a weather condition in which snow falls 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. Causes of Formation "Sun snow" is actually quite normal, and it is the result of the local convergence of cold and warm air masses. According to experts from the Anhui Provincial Meteorological Observatory, snowing on a sunny day is a weather phenomenon unique to the north, which is called "solar snow" in meteorology, just like the "solar rain" that often occurs in summer, both of which are caused by the form of clouds.

"Solar rain" is caused by high clouds, the sun is at the lower end of the clouds, but there is also the influence of cold air, so there is a natural phenomenon of rain on a sunny day; The "solar snow" is caused by translucent Altostratus clouds, which also appear under the influence of cold air, both of which are short in time and small in quantity.

It rains and snows because of the temperature, if the water vapor rises, it will rain when it encounters cold air, and in winter, it will snow when it encounters cold air due to the rise of water vapor, which is normal, because the earth rotates, so there will be sunrise and sunset.

The reason why it rains in the sky and the sun and snow actually has a lot to do with the rotation of the earth.

Rain and snow are the cycles of water in nature, which is a natural phenomenon.

Why does it rain? Will the sun come out and it will snow? It's all a matter of the clouds, the heat and the like, and then there will be these weather changes.

For the rain out of the sun and snow, this is a natural phenomenon, all of which are very mysterious, waiting for those who have the ability to dig and explore.
