Recently, everyone has heard the term "super warm winter", and we are also waiting for this year's super warm winter, many places should have ushered in super warm winter, however, many people feel colder.
Netizens laughed that their city seemed to be frozen, and they were like living in a refrigerator, so what is the situation of the "super warm winter" that experts say?
In the face of netizens' doubts, experts from the Meteorological Bureau also stood up to explain, revealing the hidden meteorological phenomena behind it. All of this seems to be closely related to terms such as the temperature difference between the equator and the poles, westerly jets, cold snaps, etc., so let's dive into the mystery behind this "warm winter".
Why does a "super warm winter" feel colder? The reason for this has to do with the temperature difference between the equator and the poles. The equatorial regions are warm and hot due to direct sunlight, while the polar regions are cold due to weak sunlight. This extreme temperature difference forms the basis of the climate, but it also lays the groundwork for some meteorological phenomena.
Experts point out that this temperature difference forms a strong westerly jet stream in the polar regions, which surrounds the poles all year round and is considered the source of cold snaps. However, due to the warming of the climate in recent years, the temperature difference between the equator and the poles has begun to shrink. This shrinkage has led to a gradual weakening of the otherwise stable westerly jet.
Against the backdrop of the narrowing of the temperature difference, the "restlessness" of the cold snap began to appear. Without the steady limitation of the westerly jet stream, a part of the cold air began to split and move southward, forming a stream of cold currents that frequently hit the mid-latitudes. This phenomenon also explains why unstable short-term sudden cold snaps have become more frequent in recent years, making people feel like "living in the refrigerator!"
El Niño: Periodic cold air harassment
Against the background of El Niño, the temperature on the continent is generally on the warmer side. However, the frequent arrival of cold air is also one of the reasons for people's ambivalent feelings about temperature. Meteorologists point out that the influence of El Niño has caused the continent to be often harassed by periods of cold air, resulting in frequent periods of warm and cold periods.
With the arrival of the beginning of winter, the chill gradually penetrates the earth. The ancients said: "Frost and cold air help autumn farmers", this is their deep understanding of the changes in the season. At this time, it is the autumn farming season, and the farmers begin to carry out their agricultural work, with the help of the cold air, which gradually causes the crops to gradually enter the dormant period and lay the foundation for the next year's harvest.
In the agricultural proverb, it is said: "The winter solstice is born as soon as the yang is born, and the yang energy gradually grows momentum." The winter solstice is the node of the growing yang energy, and it is also the time when cold waves are frequent. At this moment, the sunlight is gradually returning to the northern hemisphere, injecting warmth into the earth. However, it is precisely because of this yang energy that the instability of the westerly jet stream has increased, and the cold snap has hit frequently.
In the interpretation of this "warm winter" mystery, we learned about complex meteorological phenomena such as the temperature difference between the equator and the poles, the formation and contraction of the westerly jet stream, and the "restlessness" of the cold current. At the same time, the wisdom of solar terms and agricultural proverbs also provides us with a richer perspective. In the midst of meteorological changes, we deeply understand the beauty of the rhythm of nature, and we also cherish the magic brought by each season. Hopefully, through the understanding of meteorological knowledge, we can better adapt to and appreciate the wonders of nature.
Whether this winter will be a "super warm winter" or not, let's wait and see. Welcome to leave your understanding at the bottom of the article, and everyone can communicate together.
