The strongest rain and snow since the beginning of winter has hit many provinces. Why is a snowfall of tens of millimeters considered a blizzard?

The criteria for judging rainfall and snowfall are different. In our impression, tens of millimeters are only a few centimeters. How could it become a blizzard? In fact, this standard has reached blizzard level, and has seriously affected people's production and life, and basically blocked traffic.

First of all, let’s talk about what are Blizzard’s standards? Blizzard is calculated based on the amount of water after the snow melts. Generally, if it is greater than ten millimeters, it can be classified as a blizzard level. We may subconsciously think that only snow with more than a few dozen centimeters can become a blizzard. In fact, this is not a criterion for judging.

This reminds me of the huge blizzard in Shijiazhuang in 2009. According to historical records, it was unprecedented in 54 years. The news once reported that the deepest part of the snow reached 70 centimeters. Many cities across the province were affected by the disaster. During this blizzard disaster, six people died, more than 600,000 people were affected, and economic losses exceeded 400 million yuan.

What impressed me most was walking to work. My classmates and I got up at 5:30 to have breakfast and went out at 6:00. We talked, laughed, and walked around. Watching others fall and falling ourselves seemed to be a kind of fun. After the heavy snowfall, there are actually no buses. Snow plows clear the main roads in the city at three or four o'clock in the afternoon, and buses can only be opened at that time.

When I arrived at the company, I discovered that I was actually the first one. I went to work at 8:15. I arrived at the work unit at 8:00 and walked for a full two hours. When it was almost 9:30, the boss arrived at the company. He said to me: In April, anyone who comes today will not be considered late, and during the snowy period, anyone who arrives before 10 o'clock will not have their salary deducted.

The Prime Minister took the high-speed train to Shijiazhuang in the afternoon. He went to many supermarkets. The Prime Minister said that it is necessary to ensure that people's work and life can proceed in a normal and orderly manner. Prices cannot be raised for basic necessities such as vegetables and steamed buns. However, in the face of a major disaster, not all businesses can maintain noble moral character, and profits still need to be made.

A Chinese cabbage usually costs three to five yuan, but after the snowstorm, it increased to 20 yuan.

So, you must usually store more potatoes, eggs, and onions. No one can be sure whether it will snow tomorrow? Will it affect traffic? Will it affect travel?
