Guangzhou fell again after five years. Is this weather related to human destruction?

Guangzhou, the capital city of Guangdong, is a densely populated and economically developed city. Surprisingly, it snowed again in Guangzhou, and it wasn't snow. What is this? Ice particles? . According to the meteorological department, from the detection data of Guangzhou phased array radar and the ground temperature at that time, it is not excluded that solid particles cannot melt during the falling process. This phenomenon is defined as? Hey? . ?

In fact, there are few graupel in Guangzhou. It only happens once every five years, and the last time was in 20 16 years. It's really amazing that there are graupel in Guangzhou now. Hey (xi? N), also known as snow pill and soft hail, is solid precipitation with snow-like structure composed of white opaque ice particles. This is different from hail, which is hard and belongs to soft hail. Unlike snow, graupel is generally 0.3-2.5 mm in diameter, which is brittle and easy to crush. ?

The appearance of graupel in Guangzhou this time reminds you to keep warm. After all, it's winter now, and it's been a month since winter. Especially in special times, each of us should protect ourselves from getting sick. It has been five years since this phenomenon last appeared in Guangzhou. Explain how rare this phenomenon is. If you happen to meet it, you are very lucky.

The natural condition of our planet is not optimistic now. There are many natural phenomena that we seldom see. For example, with the development of science and technology, then the number of factories and cars increased, and smog followed, but what really disappeared was the rainbow after the rain. Like today, many things have two sides. Although the times are developing, the resources of the earth are also being excessively consumed by us. Although we are trying to improve the natural environment now, we are still consuming it. Now disposable chopsticks and disposable plastic bags continue to be used, which shows that we can't solve this phenomenon. After all, if you don't use disposable chopsticks, then there will definitely be more people worried about whether these chopsticks will be clean. Is disinfection correct? Of course, we can't avoid this by not eating out. So this is still a dilemma, and there is no good solution. We still need to do more to improve the environment.
