On the afternoon of November 5, ye dianxiu, chief of the climate service room of the National Climate Center, said that the probability of cold winter this winter is almost zero.
She said that according to the latest consultation results, the winter temperature in most parts of China this year is close to or higher than that of the whole year, and the probability of cold winter is almost zero, but it does not rule out the fluctuation of temperature during the period.
In addition, it is currently estimated that in the winter of 2019-2020, the general atmospheric circulation in the middle and high latitudes in Europe and Asia is mainly zonal circulation. The East Asian winter monsoon is weaker than that in the same period of the year, and the East Asian trough is weaker and eastward, which means that the cold air affecting China is weak, and the probability of static and stable weather in northern China is high, which is not conducive to the diffusion of pollutants.
What does cold winter mean?
It has the final say that we should not have the final say, but the weather data has the final say. When the average temperature in winter is higher than that in the whole year, it is warm winter. On the contrary, if it is lower than this standard, it is cold winter.
Division standard of cold winter
The temperature standard for dividing warm winter or cold winter is 0.5 ℃: when the average temperature in this winter (December - February of the next year) is 0.5 ℃ higher than that in previous years, this winter is warm winter; On the contrary, if the average temperature is 0.5 ℃ lower than that in previous years, it is a cold winter.
Every year, some people speculate that it is a cold winter, but in fact, it is just some speculation without scientific basis. The beginning of a cold winter is not based on temporary data, but predicted by some climate phenomena that occurred that year, and this is only a prediction for reference. After all, the weather is changing all the time, Who knows what will happen next second.
