Winter cold Frost weather revealed, how to see?Here's the answer
Autumn is getting deeper, and people are beginning to pay attention to the weather trends in winter. Winter is the coldest season of the year, and changes in cold and heat have a profound impact on life, agriculture and meteorology. Although modern weather forecasting relies on science and technology and a large amount of data analysis, there are also some methods for observing cold weather, cold winters and warm winters. Below, the author will guide you to learn how to use cold signs to ** the cold degree of winter, and understand the scientific basis of this observation method.
The basic concept of the cold season.
Frost fall is one of the 24 solar terms in China, usually on October 23 or 24 of the Gregorian calendar. There are solar terms in the name"Cold"word, but"Cold"It does not mean that there will be frosts, but rather that the temperature drops sharply, and the large temperature difference between day and night, is a sign of the transition from autumn to winter. In the cold season, the temperature plummets in the morning and evening, and the temperature is relatively high at noon, and the temperature difference between day and night increases. There are some special customs such as eating chrysanthemums, eating persimmons, climbing and other things during this season to celebrate the harvest and welcome the arrival of the cold season.
Three colds. The first wait: jackals are sacrificial beasts.
During the frost season, jackals begin to hunt prey, and sacrifice the first captured prey to the beast, and sacrifice the beast to the heavens in exchange for the original, this is the meaning of the trade and autumn gold sacrifice, just like humans sacrifice to the heavens in exchange for the original, this season also represents the cycle of life in nature.
Stage 2: Plants and trees wither and die.
In late autumn, the autumn wind is blowing, the grass begins to wither, the leaves turn yellow, and the collective falls. This is a true portrayal of autumn, all life has a process of birth, growth, decay, old age, and death, and in the cold season, the vitality of nature enters a state of deep concealment, waiting for the next year's rebirth.
The third condition: bugs and salty bowls.
During the cold season, insects (bugs) also hibernate and stop working. They hide in their burrows, with their heads up, waiting for the cold snap to end in order to come alive again in the spring. This phenomenon symbolizes nature's hibernation, the silence of winter. This is the moment when nature prepares for the long winter, they store energy and wait for new life and new beginnings in the coming year.
Is it cold this winter?
The ancients used to observe the cold weather to determine whether the next winter would be cold or warm. These methods may not have a scientific basis, but they reflect people's sensitivity to changes in meteorology. Here are some folk ways to observe:
Chilly. As the saying goes:"Freezing three feet, not a day's cold"It means that if it is not cold when it freezes three feet, it means that the current temperature is not too low, and the degree of cold is not too severe, which can be said to be a relatively warm winter.
Frost falls without rain. In addition,"No rain and warm winters"This means that if it doesn't rain during the cold snap, there's a good chance that the winter won't be too cold and will be warm.
Frost falls and the sky is clear. And there is"When the weather is clear, winter is not sad"、"The sky is clear, and the night is clear (Chinese New Year's Eve)."As the saying goes, it also says that when the weather is clear, the following days will continue to be sunny. The absence of snow in winter heralds a winter that is not only dry, but also warm.
These traditional methods, while having some charm, have no scientific basis and do not provide accurate weather forecasts. Modern meteorology uses scientific principles, extensive data analysis, and advanced technological tools, including meteorological satellites, weather radars, weather station data, and numerical weather prediction models, to improve the weather. These modern tools can provide more accurate temperature forecasts.
If a cold day is sunny, the winter may not be too cold, but if it is a rainy day, the winter will be cold. While traditional methods of observation may have some value in some cases, it is best to rely on the scientific methods of modern meteorology to know exactly whether this winter will be cold. Modern meteorology uses scientific principles, big data analysis, and advanced technology to provide accurate and reliable weather and seasonal temperature forecasts, rather than relying on traditional observation methods to determine specific dates.
