Recently, a strong cold wave has swept through most parts of the country, and the northern region has set a record low temperature, while the south has also experienced a reversal of cold and warm. **The Meteorological Observatory has issued a yellow warning for freezing, which was only once a decade ago. The forecast shows that the freezing rain is widespread, and many provinces and regions will face freezing conditions. I also received a text message informing me that the temperature in Changsha will drop by 20 and may be accompanied by sleet or light snow as a cold wave hits. So, with the arrival of the strongest cold wave this time, will this year's winter be a "cold winter"?Let's first take a look at what the ancient agricultural proverb said.
1. The agricultural proverbs of the ancients reveal the signs of a cold winter
According to the long-term practice of agricultural production, through the observation of natural phenomena and the accumulation of experience, the ancestors summed up some agricultural proverbs about the weather and farming. There is a sentence that says: "The winter moon thunders and the winter, and nine out of ten bullpens are empty." The meaning of this phrase is that the presence of thunder in the winter months is a sign that the winter will be very cold. In fact, in many places such as Zhengzhou, Henan Province, there has been recent snow accompanied by thunder, according to the old agricultural proverb, which is often accompanied by snowfall and noticeable cooling.
2. Agricultural proverbs indicate the warmth and coldness of winter
Another agricultural proverb means: at the beginning of the 11th lunar month, if it rains or snows, then the winter will be colder. And this cold wave hits, just starting from the beginning of the eleventh month of the lunar calendar, which further indicates the cold of this winter. There is also a similar proverb that "the snow is cold, and the three nines wear single clothes", which means that if the heavy snow season is already very cold, then the weather will be relatively warm in the following three nines. Generally speaking, three.
September and April 9 is the coldest time of the year, if the heavy snow solar term is already very cold, it means that the cold winter of the year has come early, and it will be relatively warm later. And now it is the heavy snow solar term, the winter solstice is coming, and then it is only 39 days. There is also a proverb related to the winter solstice: "The winter solstice is warm, and the cold is until mid-March."The winter solstice is cold, and the next spring will be warm early. This means that it is warm at the winter solstice, usually warm in winter, but colder after the year, lasting until March. If it is very cold during the winter solstice, it is a sign that the winter will be short and that it will warm up early next spring.
Through the interpretation of these agricultural proverbs, we can conclude that most agricultural proverbs are in **This year will be a cold winter. Especially the recent weather changes, the impact of the cold wave has caused many places to experience significant cooling and even snowfall. However, we can't just rely on agricultural proverbs to judge whether this winter will be cold or not. Although agricultural proverbs have a certain reference value, we also need to comprehensively consider modern science and climate change trends to be more accurate**.
1. Modern science on the winter temperature
The National Climate Center said at the press conference that according to the current monitoring data, the temperature in most parts of China is expected to be close to or higher than normal for the same period of the year this winter. In other words, there is a high probability of a "warm winter" this year. So why is there a cold wave this time?Does it mean that this year is a cold winter?
First of all, we should be clear that the so-called "warm winter" and "cold winter" do not mean that the whole winter is not cold or very warm. Rather, it is judged by the temperature conditions throughout the winter. Therefore, we cannot draw conclusions based solely on a cold spell or a period of warmth.
Secondly, the cold and warm in winter are not exactly the same as the cold and warm. Colder or warmer is simply relative to the long-term average, and warmer or cooler than average temperatures can be referred to as warmer or colder. Whether it is a cold winter or a warm winter has a stricter criterion.
At the same time, El Niño has occurred this year with moderate intensity and is expected to continue until next spring. The occurrence of El Niño will not only lead to a warmer winter in China, but also lead to frequent extreme weather, such as cliff-like cooling or rocket-like warming, and will also have an impact on rainfall and snowfall.
China's climate is complex and diverse, and there are many influencing factors. Even though this year is called a warm winter, it is inevitable that there will be a phased cooling. Although the cold wave may be delayed, it will not be absent, and the scene of heavy snow will definitely appear.
Finally, it should be emphasized that whether this winter is cold or warm, the cold wave weather has already had an impact on many parts of the country. For ordinary people, it is very important to pay close attention to weather forecasts and warnings in order to cope with the possible adverse effects of periodic low temperatures, rain and snow.
Therefore, although agricultural proverbs have a certain reference value in terms of weather, we also need to consider modern scientific methods and climate change trends comprehensively to make more accurate ones. Only by waiting until the end of winter can we determine whether this year will be cold or warm based on actual climate data.
