Is the earliest autumn in the past 40 years will be colder this winter?

Original title: Is the shortest autumn in the past 40 years will be colder this winter? Spring, summer.

This is a ridicule, saying that autumn is very short, "" is gone.

However, Chengdu has made it a reality. Chengdu has been officially entered on November 7, which is more than 22 days in advance. And when positive winter encounters late autumn, this year, Chengdu’s autumn is the shortest in 1982. The shortest autumn encounters the earliest winter, what will be cold in winter? The winter and the earth are 上海419龙凤桑拿网 officially entered on November 7th. This is a Meteorological Officer in November 15. Why is it "over" This is because it is time to determine the change in the season.

According to the definition of meteorology, when the average temperature in 5 consecutive days is less than 10 ° C, the first average temperature is below 10 ° C in the winter day.

  As a representative of Wenjiang National Meteorological Observatory, the average temperature began to be less than 10 ° C (12 days) from November 7th, from November 10th to 14 days of sliding average temperature below 10 At ° C, it is determined that 2021 Chengdu’s winter time is November 7th, that is, the day of life. Many people in autumn in 2000 should remember, Chengdu is in autumn in the last month. Indeed, this year, Chengdu’s autumn is late.

A few days ago in the National Day holiday, Chengdu is still in the summer, until a strong cold air, finally reminded the late autumn debut.

On October 4, Chengdu ushered in autumn since 2000.

  Although the autumn is late 22 days in advance, winter is very active.

  It is also a change season that has brought most of the strong cold air in the country. Starting on November 4th, the strongest cold wave in the second half of this year quickly frozen my country. In the Northern Division, the Sichuan High-altitude Mountain Area also added snowfall.

  Chengdu is in the winter.

  The winter time in Chengdu is November 29th, this year, I have been in advance for 22 days in advance, and I was ahead of 2015 (I went into the winter on December 12 that year). "The shortest" will not welcome "the coldest" winter after autumn? This way, Chengdu is only 34 days this year, which is the shortest fall since 1982. Plus "Lenna" that is talking about recently. Many people are worried, this winter will not be particularly cold.

  The Ranina event can be seen as "cold interpolation" in the context of global warming. From historical data, in most lanna incidents, my country’s cold air activities are frequent than all year round, and most of the central and eastern parties are more than normal. The low probability is large.

  From the perspective of Chengdu Meteorological Observatory "Winter Climate Trend", the average temperature in winter is expected to be ° C, which is less than the same period of time. The low is mainly in January and February 2022.

The average temperature in December this year is flat. The average temperature in January is ° C, which is less than the same period (° C) in the same period of time (° C); in February is ° C, the same period (° C) is low in the same period of the year. C.

  Chengdu Meteorological Observatory is expected to affect the cold air activities in Chengdu in 2021-2022, the strength of Chengdu is frequent, the average temperature is overall, the temperature is low, and the temperature in the season is obvious. In mid-January to mid-January The probability of strong cooling or extreme low temperature 松江哪有kb的地方 event is large, and there is a low-temperature rain and snow freezing weather process in the mountainous area.
