In the early morning of January 28, when many netizens in Nanjing Hefei woke up and looked out of the window excitedly, imagining that the world wrapped in silver had not arrived as promised, many netizens were disappointed. Even in the morning, the sky in Hefei, Anhui Province, began to shine, and the sunlight began to shine through the clouds, which made many netizens call "deceived" directly, saying where did the good blizzard go? In fact, in addition to Hefei, the snow in Nanjing and Shanghai-Nanjing cities today has not arrived as promised.
Of course, it's not that the snow is gone, it's that the snow is off track – just as the changes in the previous forecasts, both the Central Meteorological Observatory and the supercomputer's forecasts have clearly further adjusted the Blizzard Center to the south. For example, the Central Meteorological Observatory believes in the forecast from January 29 to January 30 that the blizzard center will be transferred south to the southern Anhui and western Zhejiang lines, and the snowfall on the Nanjing line of Hefei will be further reduced. However, the obvious reduction in the risk of snow and freezing is actually a good thing.
Then some netizens will ask: How did the said good Blizzard deviate? Weather forecast so inaccurate? Blizzard forecasting is a world problem. In early 2015, the supercomputer model predicted that there would be a "blizzard of the century" of nearly 1 meter in New York, when the entire city of New York was in the face of a great enemy, and the subway was shut down early to cope with it. As a result, because the cyclone ran off, New York turned late in the snow, and it ended up being just an ordinary snow.
Why Blizzard is difficult to predict, because Blizzard is "weather on the tip of the knife" - it requires a very precise combination of water vapor and cold air, and the slightest deviation between water vapor and cold air will lead to very different results. On the mainland, because of the complex terrain and dense population, Blizzard forecasting is far more difficult than in the United States. This is because the impact of the blizzard is too great and must be prevented in advance. Therefore, when the possibility of a blizzard arises, it is necessary to prepare in advance, and some things that seem to be "done in vain" must also be done; of course, if it does not happen, everyone is disappointed and emotional, and some emotional language is also understandable. This is what it means to "listen to scolding rather than crying."
Although the snowfall in Hefei Nanjing has been deviated, it does not mean that the risk of heavy snowfall in the entire south has been completely lifted, in fact, this morning, many places in Hubei, including Wuhan, have been snowflakes, heavy snow has arrived, Hunan, Jiangxi, Guizhou, Zhejiang and other places the risk of snowfall and freezing has not been lifted, still need to remain vigilant.
