It snows in Gansu! Why does it snow in Gansu, which is still in the dog days?

Snow is a natural phenomenon. When the temperature and humidity reach certain conditions, it will appear. We know that it snows all the year round in some places, and it never snows in some places. It all depends on the climatic conditions, it is not static. It is a normal phenomenon in Gansu. If the conditions for snow are met, it will naturally snow. According to past experience, people find it incredible, but it doesn't mean anything. The only bad thing is that it is not good for some crops that are not cold-tolerant, which will affect.

The climate of the earth is not controlled by one place, but determined by the big environment and climate. Any over-interpretation is meaningless. If you know a little about climate geography, this extreme phenomenon was quite common in the past. Now that the network information is developed, people will know it soon if there is a slight sign of trouble. Maybe it's been a long time, and it can't even spread, so people don't know it or have no records. People always think it doesn't snow in the south. In fact, when the altitude reaches a certain height and the temperature and humidity are suitable, it will snow in the south, and we know that there is a broken bridge, one of the ten scenic spots of the West Lake in Hangzhou, where there will be snow, so climate change has existed since ancient times.

Principle of Snow: Snow is a natural phenomenon. The water vapor in the air condenses and then falls to the ground again. Water is the foundation of all kinds of life on the earth, and its changes and movements have created our world today. On the earth, water is constantly circulating. The water in the ocean and on the ground is heated and evaporated into the sky. The water vapor moves to other places with the wind. When they encounter cold air, they form precipitation and return to the earth's surface. There are two kinds of precipitation: one is liquid precipitation, which is rain; The other is solid precipitation, which is snow or hail.

In Gansu, which used to have a dry climate, the humidity of the air rarely reached this condition. Even if the temperature is relatively low, it is impossible to snow, not for other reasons. The humidity is relatively high this year, so it can be said that it is a rare natural landscape to snow at the same temperature. I believe that many people who love traveling and photography have got good films, and those children who have never seen snow will also have fun.

The impact of short-term snowfall on crops is also limited, especially in Gansu, where the temperature difference between day and night is relatively large and the cold resistance of crops is relatively strong. I believe the loss will not be particularly great. In addition, today's agriculture has participated in insurance, all as a guarantee. I hope the peasant brothers will lose less.

In dog days, it may snow anywhere. As long as the temperature and humidity are right, it will snow. There is no other reason. It snows all the year round in some places, which is also the reason.
